text: Halley's Comet, named after English astronomer Edmund Halley who first demonstrated its periodicity, returns to the vicinity of the Sun and Earth approximately every 76 years. Since comets are believed to be the most primordial objects in the solar system, their study is of great importance to planetary science. At the time of the 1986 return (technically, "apparition") of the comet, astronomical telescopes and related instrumentation were vastly more sensitive than for any previous apparition. Consequently, the International Halley Watch (IHW) was organized to stimulate, standardize, collect, and archive observations of the comet.

text: Pluto has five known moons. Its largest moon Charon is more than half the size of Pluto itself, and large enough to orbit a point outside Pluto's surface. In fact, each orbits the common barycenter between them, with Pluto's orbit entirely enclosed by Charon's; thus they form a binary system informally referred to as a double dwarf planet. Pluto's four other moons, Nix, Hydra, Kerberos, and Styx, are far smaller and orbit the Pluto–Charon system.

text: Because of its unstable nature, astronomers now consider the scattered disc to be the place of origin for most periodic comets in the Solar System, with the centaurs, a population of icy bodies between Jupiter and Neptune, being the intermediate stage in an object's migration from the disc to the inner Solar System. Eventually, perturbations from the giant planets send such objects towards the Sun, transforming them into periodic comets. Many Oort cloud objects are also thought to have originated in the scattered disc. Detached objects are not sharply distinct from scattered disc objects, and some such as Sedna have sometimes been considered to be included in this group.

text: The time frame of the Solar System's formation has been determined using radiometric dating. Scientists estimate that the Solar System is 4.6 billion years old. The oldest known mineral grains on Earth are approximately 4.4 billion years old. Rocks this old are rare, as Earth's surface is constantly being reshaped by erosion, volcanism, and plate tectonics. To estimate the age of the Solar System, scientists use meteorites, which were formed during the early condensation of the solar nebula. Almost all meteorites (see the Canyon Diablo meteorite) are found to have an age of 4.6 billion years, suggesting that the Solar System must be at least this old.

text: In phases of the meteorites Semarkona and Chervony Kut, a correlation between the concentration of Ni, the granddaughter of Fe, and the abundance of the stable iron isotopes provided evidence for the existence of Fe at the time of formation of the Solar System. Possibly the energy released by the decay of Fe, along with that released by Al, contributed to the remelting and differentiation of asteroids after their formation 4.6 billion years ago. The abundance of Ni present in extraterrestrial material may bring further insight into the origin and early history of the Solar System.

text: Jupiter's mass is 2.5 times that of all the other planets in the Solar System combined—this is so massive that its barycenter with the Sun lies above the Sun's surface at 1.068 solar radii from the Sun's center. Jupiter is much larger than Earth and considerably less dense: its volume is that of about 1,321 Earths, but it is only 318 times as massive. Jupiter's radius is about 1/10 the radius of the Sun, and its mass is 0.001 times the mass of the Sun, so the densities of the two bodies are similar. A "Jupiter mass" ( or ) is often used as a unit to describe masses of other objects, particularly extrasolar planets and brown dwarfs. So, for example, the extrasolar planet HD 209458 b has a mass of , while Kappa Andromedae b has a mass of .

text: The Pluto–Charon system is one of the few in the Solar System whose barycenter lies outside the primary body; 617 Patroclus is a smaller example, and the Sun–Jupiter system is the only larger one. The similar sizes of Charon and Pluto has prompted some astronomers to call it a double dwarf planet. The system is also unusual among planetary systems in that each is tidally locked to the other, which means that Pluto and Charon always have the same hemisphere facing each other. From any position on either body, the other is always at the same position in the sky, or always obscured. This also means that the rotation period of each is equal to the time it takes the entire system to rotate around its barycenter.

text: The objects now called "brown dwarfs" were theorized to exist in the 1960s by Shiv S. Kumar. They were originally called black dwarfs, a classification for dark substellar objects floating freely in space that were not massive enough to sustain hydrogen fusion. However: a) the term black dwarf was already in use to refer to a cold white dwarf; b) red dwarfs fuse hydrogen, and c) these objects may be luminous at visible wavelengths early in their lives. Because of this, alternate names for these objects were proposed, including planetar and substar. In 1975, Jill Tarter suggested the term "brown dwarf", using brown as an approximate color; the term was used for this kind of objects  since.

text: Planetesimals from the outer disc are embedded in all parts of the asteroid belt, remaining as P- and D-type asteroids. While Jupiter's resonances sweep across the asteroid belt outer disk planetesimals are captured by its inner resonances, evolve to lower eccentricities via secular resonances with in these resonances, and are released onto stable orbits as Jupiter's resonances move on. Others planetesimals are implanted in the asteroid belt during encounters with the ice giant, either directly leaving them with aphelia higher than that of the ice giant's perihelia, or by removing them from a resonance. Jumps in Jupiter's semi-major axis during its encounters with the ice giant shift the locations of its resonances, releasing some objects and capturing others. Many of those remaining after its final jump, along with others captured by the sweeping resonances as Jupiter migrates to its current location, survive as parts of the resonant populations such as the Hildas, Thule, and those in the 2:1 resonance. Objects originating in the asteroid belt can also be captured in the 2:1 resonance, along with a few among the Hilda population. The excursions the ice giant makes into the asteroid belt allows the icy planetesimals to be implanted farther into the asteroid belt, with a few reaching the inner asteroid belt with semi-major axis less than 2.5 AU. Some objects later drift into unstable resonances due to diffusion or the Yarkovsky effect and enter Earth-crossing orbits, with the Tagish Lake meteorite representing a possible fragment of an object that originated in the outer planetesimal disk. Numerical simulations of this process can roughly reproduce the distribution of P- and D-type asteroids and the size of the largest bodies, with differences such as an excess of objects smaller than 10 km being attributed to losses from collisions or the Yarkovsky effect, and the specific evolution of the planets in the model.

text: This list contains a selection of objects estimated to be between 100 and 200 km in radius (200 and 400 km in diameter). The largest of these may lie above the boundary for hydrostatic equilibrium, but most are irregular. Most of the trans-Neptunian objects listed with a radius smaller than 200 km have "assumed sizes based on a generic albedo of 0.09" since they are too far away to directly measure their sizes with existing instruments. Mass switches from 10 kg to 10 kg (Zg). Main-belt asteroids have orbital elements constrained by (2.0 AU < a < 3.2 AU; q > 1.666 AU) according to JPL Solar System Dynamics (JPLSSD). This list is not complete, missing many poorly known TNOs.

text: Researchers have found that the mineral, which has the same atomic arrangement as a man-made component of some types of concrete, forms under low pressure at a temperature of at least . These conditions of high temperature and low pressure are consistent with a hypothesis that the krotite grains found in the meteorite formed as high-temperature condensates from the solar nebula from which the solar system formed, approximately 4.6 billion years ago. Thus, they are likely to be among the earliest minerals formed in the solar system.

text: Others have tied it to Tyche; the name proposed by John Matese and Daniel Whitmire of the University of Louisiana at Lafayette for an object they believe to be influencing the orbits of comets in the Oort cloud. In February, 2011, Whitmire and his colleagues took their hypothesis to the public in an article in The Independent, in which they named the object "Tyche" and claimed that evidence for its existence would be found once data from the WISE infrared telescope was collated, leading to a spike in calls to astronomers. The name, after the "good sister" of the Greek goddess Nemesis, was chosen to distinguish it from the similar Nemesis hypothesis as, unlike Nemesis, Matese and Whitmire do not believe that their object poses a threat to Earth. Also, this object, if it exists, would, like Nemesis, have an orbit hundreds of times longer than that proposed for Nibiru, and never come near the inner Solar System. In 2014, NASA announced that the WISE survey had ruled out the existence of Tyche as its proponents had defined it.

text: Consequently, the burden of building canals passed to the states. The Erie Canal in New York proved to be an early success after it was completed in 1825. The Ohio House and Senate had worked for two decades to pass legislation authorizing a canal, gaining success with the Act of February 4, 1825, which finally approved the construction of the Ohio canal system. The canal was largely state-funded, using money acquired from selling off land near where the canals were to be dug. The state government planned and built two canals in the state: the Miami and Erie Canal, from Cincinnati to Toledo, connecting the Ohio River and Lake Erie; and the Ohio and Erie Canal, which connected Cleveland, another lake port, to Portsmouth. This system provided the interior of Ohio with new travel routes that effectively extended to the major Atlantic port of New York City, as merchants could ship goods through Lake Erie, the Erie Canal and the Hudson River to New York.

text: When a planet is found by the radial-velocity method, its orbital inclination i is unknown and can range from 0 to 90 degrees. The method is unable to determine the true mass (M) of the planet, but rather gives a lower limit for its mass, M sini. In a few cases an apparent exoplanet may be a more massive object such as a brown dwarf or red dwarf. However, the probability of a small value of i (say less than 30 degrees, which would give a true mass at least double the observed lower limit) is relatively low (1−(√3)/2 ≈ 13%) and hence most planets will have true masses fairly close to the observed lower limit.

text: Following guidelines established by the IAU that classical Kuiper belt objects be given names of mythological beings associated with creation, in September 2006 the Caltech team submitted formal names from Hawaiian mythology to the IAU for both (136108) 2003 EL and its moons, in order "to pay homage to the place where the satellites were discovered". The names were proposed by David Rabinowitz of the Caltech team. Haumea is the tutelary goddess of the island of Hawaii, where the Mauna Kea Observatory is located. In addition, she is identified with Papa, the goddess of the earth and wife of Wākea (space), which is appropriate because 2003 EL is thought to be composed almost entirely of solid rock, without the thick ice mantle over a small rocky core typical of other known Kuiper belt objects. Lastly, Haumea is the goddess of fertility and childbirth, with many children who sprang from different parts of her body; this corresponds to the swarm of icy bodies thought to have broken off the dwarf planet during an ancient collision. The two known moons, also believed to have been born in this manner, were thus named after two of Haumea's daughters, Hiiaka and Nāmaka.

text: One of the main problems when generating hypotheses on the formation and evolution of objects in the Solar System is the lack of samples that can be analysed in the laboratory, where a large suite of tools are available and the full body of knowledge derived from terrestrial geology can be brought to bear. Fortunately, direct samples from the Moon, asteroids and Mars are present on Earth, removed from their parent bodies and delivered as meteorites. Some of these have suffered contamination from the oxidising effect of Earth's atmosphere and the infiltration of the biosphere, but those meteorites collected in the last few decades from Antarctica are almost entirely pristine.

text: When the definition of "dwarf planet" was instated at the IAU General Assembly of 2006, Ceres, Pluto and Eris were identified by name as the initial members of the dwarf planet class. However, precise regulations as to how hydrostatic equilibrium would be measured were left undefined for the time being. Without an official procedure for calculating the lower bound of size to be a "dwarf planet", no further bodies could be formally recognized as either dwarf planets or plutoids.

text: Planetary surfaces are found throughout the Solar System, from the inner terrestrial planets, to the asteroid belt, the natural satellites of the gas giant planets and beyond to the Trans-Neptunian objects.  Surface conditions, temperatures and terrain vary significantly due to a number of factors including Albedo often generated by the surfaces itself.  Measures of surface conditions include surface area, surface gravity, surface temperature and surface pressure. Surface stability may be affected by erosion through Aeolian processes, hydrology, subduction, volcanism, sediment or seismic activity. Some surfaces are dynamic while others remain unchanged for millions of years.

text: ) is the smallest identified dwarf planet in the Solar System, but is significantly the largest object in the asteroid belt. It was discovered on 1 January 1801 by Giuseppe Piazzi, and is named after Ceres, the Roman goddess of growing plants, the harvest, and of motherly love. It was the first asteroid discovered, taking up about one-third of the entire mass of its asteroid belt. The classification of Ceres has changed more than once and has been the subject of some disagreement. Johann Elert Bode believed Ceres to be the "missing planet" he had proposed to exist between Mars and Jupiter, at a distance of 419 million km (2.8 AU) from the Sun. Ceres was assigned a planetary symbol, and remained listed as a planet in astronomy books and tables for about half a century. The 2006 debate surrounding Pluto and what constitutes a planet led to Ceres being considered for reclassification as a planet, but in the end Ceres and Pluto were classified as the first members of the new dwarf planet category.

text: The sudden brightening of comet 17P/Holmes in 2007 showed the importance of the activity of the nucleus in the comet's brightness. On October 23–24, 2007, the comet suffered a sudden outburst which caused it to brighten by factor of about half a million. It unexpectedly brightened from an apparent magnitude of about 17 to about 2.8 in a period of only 42 hours, making it visible to the naked eye. All these temporarily made comet 17P the largest (by radius) object in the Solar System although its nucleus is estimated to be only about 3.4 km in diameter.

text: The age determined from the Canyon Diablo meteorite has been confirmed by hundreds of other age determinations, from both terrestrial samples and other meteorites. The meteorite samples, however, show a spread from 4.53 to 4.58 billion years ago. This is interpreted as the duration of formation of the solar nebula and its collapse into the solar disk to form the Sun and the planets. This 50 million year time span allows for accretion of the planets from the original solar dust and meteorites.

text: The migration of the outer planets is necessary to account for the existence and properties of the Solar System's outermost regions. Beyond Neptune, the Solar System continues into the Kuiper belt, the scattered disc, and the Oort cloud, three sparse populations of small icy bodies thought to be the points of origin for most observed comets. At their distance from the Sun, accretion was too slow to allow planets to form before the solar nebula dispersed, and thus the initial disc lacked enough mass density to consolidate into a planet. The Kuiper belt lies between 30 and 55 AU from the Sun, while the farther scattered disc extends to over 100 AU, and the distant Oort cloud begins at about 50,000 AU.

text: Kridsadaporn is amongst another group of bodies [Mars-crossing (MC) and/or near-Earth object (NEO) populations] that may have originated from the main asteroid belt as fragments injected into a mean-motion resonance or secular resonance, developing increasingly higher orbital eccentricity over time resulting in the perihelion distance becoming smaller than the aphelion distances of the inner planets. At their birth, near-earth asteroids (NEAs) and MC orbits are in resonance, and when their orbital eccentricity becomes large enough, to the point that their orbits cross those of the inner planets, their orbits then become modified in a random-walk fashion. This results in a complex interplay between planetary encounters and resonances which may lead to a range of unexpected outcomes including cometary-type orbits; solar collisions; or, eventual ejection from the Solar System.

text: This list contains all known stars and brown dwarfs at a distance of up to 5 parsecs (16.3 light-years) from the Solar System. In addition to the Solar System, there are another 56 stellar systems currently known lying within this distance. These systems contain a total of 60 hydrogen-fusing stars (of which 50 are red dwarfs), 13 brown dwarfs, and 4 white dwarfs. Despite the relative proximity of these objects to Earth, only nine of them have an apparent magnitude less than 6.5, which means only about 12% of these objects can be observed with the naked eye. Besides the Sun, only three are first-magnitude stars: Alpha Centauri, Sirius, and Procyon. All of these objects are located in the Local Bubble, a region within the Orion–Cygnus Arm of the Milky Way.

text: The Allende meteorite is the largest carbonaceous chondrite ever found on Earth. The fireball was witnessed at 01:05 on February 8, 1969, falling over the Mexican state of Chihuahua. After breaking up in the atmosphere, an extensive search for pieces was conducted and it is often described as "the best-studied meteorite in history". The Allende meteorite is notable for possessing abundant, large calcium-aluminium-rich inclusions, which  are among the oldest objects formed in the Solar System.

text: Haumea has an orbital period of 284 Earth years, a perihelion of 35 AU, and an orbital inclination of 28°. It passed aphelion in early 1992, and is currently more than 50 AU from the Sun. Haumea's orbit has a slightly greater eccentricity than that of the other members of its collisional family. This is thought to be due to Haumea's weak 7:12 orbital resonance with Neptune gradually modifying its initial orbit over the course of a billion years, through the Kozai effect, which allows the exchange of an orbit's inclination for increased eccentricity.

text: In the war's aftermath, a science called psychodynamics is created.  Like Isaac Asimov's psychohistory, psychodynamics can be used to predict and guide the future course of social evolution.  An organization called the Psychotechnic Institute is founded in the 1970s that uses psychodynamics to influence government policy and popular attitudes, with the goal of redirecting society towards greater rationality and internationalism.  The Psychotechnic Institute assists a reborn United Nations based in Rio de Janeiro to become a world government, and also encourages space colonization.  The Order of Planetary Engineers is established on the Moon with the goal of assisting in the terraforming of the Solar System.  Early in the 22nd century, as the settlements on the Moon, Venus, Mars, and the Asteroid Belt grow in importance, the United Nations is succeeded by the Solar Union.

text: Though Pluto is the largest Kuiper belt object discovered, Neptune's moon Triton, which is slightly larger than Pluto, is similar to it both geologically and atmospherically, and is thought to be a captured Kuiper belt object. Eris (see above) is about the same size as Pluto (though more massive) but is not strictly considered a member of the Kuiper belt population. Rather, it is considered a member of a linked population called the scattered disc.

text: Several ellipsoid-model calculations of Haumea's dimensions have been made. The first model produced after Haumea's discovery was calculated from ground-based observations of Haumea's light curve at optical wavelengths: it provided a total length of 1,960 to 2,500 km and a visual albedo (p) greater than 0.6. The most likely shape is a triaxial ellipsoid with approximate dimensions of 2,000 x 1,500 x 1,000 km, with an albedo of 0.71. Observations by the Spitzer Space Telescope give a diameter of  and an albedo of , from photometry at infrared wavelengths of 70 μm. Subsequent light-curve analyses have suggested an equivalent circular diameter of 1,450 km. In 2010 an analysis of measurements taken by Herschel Space Telescope together with the older Spitzer Telescope measurements yielded a new estimate of the equivalent diameter of Haumea—about 1300 km. These independent size estimates overlap at an average geometric mean diameter of roughly 1,400 km. This makes Haumea one of the largest trans-Neptunian objects discovered, smaller than , , probably , and possibly , and larger than , , and .

text: Detached objects have perihelia much larger than Neptune's aphelion. They often have highly elliptical, very large orbits with semi-major axes of up to a few hundred astronomical units (AU, the radius of Earth's orbit). Such orbits cannot have been created by gravitational scattering by the giant planets (in particular, Neptune). Instead, a number of explanations have been put forward, including an encounter with a passing star or a distant planet-sized object, or Neptune itself (which may once have had a much more eccentric orbit, from which it could have tugged the objects to their current orbit) or ejected planets (present in the early Solar System that were ejected).

text: The Collaborative Asteroid Lightcurve Link (CALL) classifies the asteroid as a member of the Eunomia family, a large group of S-type asteroids and the most prominent family in the intermediate main-belt, while, based on its concurring orbital elements, Alvarez-Candal from the Universidad Nacional de Córdoba and others, group the asteroid into the Maria family, which is named after its namesake, the asteroid 170 Maria. It is an old-type asteroid family, about  years old, located near the area of a 3:1 resonances with Jupiter that supplies near-Earth asteroids to the inner Solar System (also see Kirkwood gap). It is estimated that every 100 million years, about 37 to 75 Maria asteroids larger than 1 kilometer become near-Earth objects.

text: A very different Comet was introduced in Supergirl #14 (October 1997). This version was originally introduced as a hero with flight and cold-generation powers. Comet's appearance was unclear, as when using his powers he was surrounded by an aura of cold that made him resemble an actual comet. Comet looked like a man with three fingers, horse-like legs, long white hair, and a star mark on his forehead. There was a lot of speculation about who Comet was, but it was revealed that Comet was Andrea Martinez, a bisexual stand-up comic, who like her friend Linda Danvers (who could turn into Supergirl), could shape-shift between her human and super-powered forms (however, Comet's change also involved changing gender, from the female Andrea to the male Comet).

text: 101 Helena is a rocky main-belt asteroid. It was discovered by Canadian-American astronomer J. C. Watson on August 15, 1868, and was named after Helen of Troy in Greek mythology. Radar observations were made of this object on Oct 7 and 19, 2001 from the Arecibo Observatory. Analysis of the data gave an estimated ellipsoidal diameter of 71×63×63 ± 16% km. The diameter estimated from IRAS infrared measurements is 66 km. It is classified as an S-type asteroid in the Tholen system.

text: From its discovery in 1846 until the subsequent discovery of Pluto in 1930, Neptune was the farthest known planet. When Pluto was discovered it was considered a planet, and Neptune thus became the penultimate known planet, except for a 20-year period between 1979 and 1999 when Pluto's elliptical orbit brought it closer to the Sun than Neptune. The discovery of the Kuiper belt in 1992 led many astronomers to debate whether Pluto should be considered a planet or as part of the Kuiper belt. In 2006, the International Astronomical Union defined the word "planet" for the first time, reclassifying Pluto as a "dwarf planet" and making Neptune once again the outermost known planet in the Solar System.

text: Haumea is the largest member of its collisional family, a group of astronomical objects with similar physical and orbital characteristics thought to have formed when a larger progenitor was shattered by an impact. This family is the first to be identified among TNOs and includes—beside Haumea and its moons— (≈364 km),  (≈174 km),  (≈200 km),  (≈230 km), and  (≈252 km). Brown and colleagues proposed that the family were a direct product of the impact that removed Haumea's ice mantle, but a second proposal suggests a more complicated origin: that the material ejected in the initial collision instead coalesced into a large moon of Haumea, which was later shattered in a second collision, dispersing its shards outwards. This second scenario appears to produce a dispersion of velocities for the fragments that is more closely matched to the measured velocity dispersion of the family members.

text: Samples of iron meteorite from Canyon Diablo (Meteor Crater) Arizona were found to have the least radiogenic composition of any material in the solar system. The U/Pb ratio was so low that no radiogenic decay was detected in the isotopic composition. As illustrated in figure 1, this point defines the lower (left) end of the isochron. Therefore, troilite found in Canyon Diablo represents the primeval lead isotope composition of the solar system, dating back to 4.55 +/- 0.07 Byr.

text: Being distant from the Sun and major planets, Kuiper belt objects are thought to be relatively unaffected by the processes that have shaped and altered other Solar System objects; thus, determining their composition would provide substantial information on the makeup of the earliest Solar System. However, due to their small size and extreme distance from Earth, the chemical makeup of KBOs is very difficult to determine. The principal method by which astronomers determine the composition of a celestial object is spectroscopy. When an object's light is broken into its component colors, an image akin to a rainbow is formed. This image is called a spectrum. Different substances absorb light at different wavelengths, and when the spectrum for a specific object is unravelled, dark lines (called absorption lines) appear where the substances within it have absorbed that particular wavelength of light. Every element or compound has its own unique spectroscopic signature, and by reading an object's full spectral "fingerprint", astronomers can determine what it is made of.

text: Haumea is a plutoid, a dwarf planet beyond Neptune's orbit. Its classification as a dwarf planet means it is presumed to be massive enough to have been rounded by its own gravity into a shape in hydrostatic equilibrium, but not massive enough to have cleared its neighbourhood of similar objects.  Haumea appears to have a triaxial ellipsoid shape resulting its rapid rotation complicated by tidal interactions with its moons.  This contrasts with the simpler oblate shape typically assumed by less rapidly rotating astronomical bodies such as the Earth, Jupiter (or a water balloon tossed with moderate spin).  Like the earth, Haumea is flattened at the poles (indeed much more so), but its equator, instead of being round like the Earth's, is elliptical, with two big bulges 180 degrees apart in longitude, buoyed up, as it were, by the greater centrifugal force they experience by virtue of being farther from the axis of rotation.  In other words, Haumea is spinning so fast that if it spun much faster these bulges would distort into a dumbbell shape and split the planet in two. Haumea was initially listed as a classical Kuiper belt object in 2006 by the Minor Planet Center, but no longer. The nominal trajectory suggests that it is in the weak 7:12 resonance with Neptune (orbiting the Sun 7 times for every 12 orbits of Neptune), because its perihelion distance of 35 AU is near the limit of stability with Neptune. There are precovery images of Haumea dating back to March 22, 1955 from the Palomar Mountain Digitized Sky Survey. Further observations of the orbit will be required to verify its dynamic status.

text: The issue of a clear definition for planet came to a head in January 2005 with the discovery of the trans-Neptunian object Eris, a body more massive than the smallest then-accepted planet, Pluto. In its August 2006 response, the International Astronomical Union (IAU), recognised by astronomers as the world body responsible for resolving issues of nomenclature, released its decision on the matter during a meeting in Prague in the Czech republic. This definition, which applies only to the Solar System, states that a planet is a body that orbits the Sun, is massive enough for its own gravity to make it round, and has "cleared its neighbourhood" of smaller objects around its orbit. Under this new definition, Pluto and the other trans-Neptunian objects do not qualify as planets. The IAU's decision has not resolved all controversies, and while many scientists have accepted the definition, some in the astronomical community have rejected it outright.

text: The asteroid belt formed from the primordial solar nebula as a group of planetesimals. Planetesimals are the smaller precursors of the protoplanets. Between Mars and Jupiter, however, gravitational perturbations from Jupiter imbued the protoplanets with too much orbital energy for them to accrete into a planet. Collisions became too violent, and instead of fusing together, the planetesimals and most of the protoplanets shattered. As a result, 99.9% of the asteroid belt's original mass was lost in the first 100 million years of the Solar System's history. Some fragments eventually found their way into the inner Solar System, leading to meteorite impacts with the inner planets. Asteroid orbits continue to be appreciably perturbed whenever their period of revolution about the Sun forms an orbital resonance with Jupiter. At these orbital distances, a Kirkwood gap occurs as they are swept into other orbits.

A non-satellite body fulfilling only the first criterion is termed a "small Solar System body" (SSSB).  Initial drafts planned to include dwarf planets as a subcategory of planets, but because this could have led to the addition of several dozens of planets into the Solar System, this draft was eventually dropped. The definition was a controversial one,  and has drawn both support and criticism from different astronomers, but has remained in use.

text: Hiʻiaka orbits Haumea nearly circularly every 49 days. Namaka orbits Haumea in 18 days in a moderately elliptical, non-Keplerian orbit, and as of 2008 was inclined 13° with respect to Hiʻiaka, which perturbs its orbit. Because the impact that created the moons of Haumea is thought to have occurred in the early history of the Solar System, over the following billions of years it should have been tidally damped into a more circular orbit. Namaka's orbit has likely been disturbed by orbital resonances with the more-massive Hiʻiaka due to converging orbits as they moved outward from Haumea due to tidal dissipation. They may have been caught in and then escaped from orbital resonance several times; they currently are in or at least close to an 8:3 resonance. This resonance strongly perturbs Namaka's orbit, which has a current precession of its argument of periapsis by about −6.5° per year, a precession period of 55 years.

text: Kamacite sulfurization has been done experimentally in laboratory conditions. Sulfurization resulted in three distinct phases: a mono-sulfide solid solution (Fe,Ni,Co)1-xS, a pentlandite phase (Fe,Ni,Co)9-xS8, as well as a P-rich phase. This was done in a lab to construct conditions concurrent with that of the solar nebula. With this information it would be possible to extract information about the thermodynamic, kinetic, and physical conditions of the early solar system. This still remains speculatory as many of the sulfides in meteorites are unstable and have been destroyed. Kamacite also alters to tochilinite (Fe2+5-6(Mg, Fe2+)5S6(OH)10). This is useful for giving clues as to how much the meteorite as a whole has been altered. Kamacite to tochilinite alteration can be seen in petrologic microscopes, scanning electron microscope, and electron microprobe analysis. This can be used to allow researchers to easily index the amount of alteration that has taken place in the sample. This index can be later referenced when analyzing other areas of the meteorite where alteration is not as clear.

text: Ethan Siegel, who is deeply skeptical of the existence of an undiscovered new planet in the Solar System, nevertheless speculates that at least one super-Earth, which have been commonly discovered in other planetary systems but have not been discovered in the Solar System, might have been ejected from the inner Solar System due to the inward migration of Jupiter in the early Solar System. Hal Levison thinks that the chance of an ejected object ending up in the inner Oort cloud is only about 2%, and speculates that many objects must have been thrown past the Oort cloud if one has entered a stable orbit.

text: The cause of the X-ray emission is thought to be a combination of two mechanisms.  Interactions between energetic solar wind particles and cometary material evaporating from the nucleus is likely to contribute significantly to this effect. Reflection of solar X-rays is seen in other Solar System objects such as the Moon, but a simple calculation assuming even the highest x-ray reflectivity possible per molecule or dust grain is not able to explain the majority of the observed flux from Hyakutake, as the comet's atmosphere is very tenuous and diffuse. Observations of comet C/1999 S4 (LINEAR) with the Chandra satellite in 2000 determined that X-rays observed from that comet were produced predominantly by charge exchange collisions between highly charged carbon, oxygen and nitrogen minor ions in the solar wind, and neutral water, oxygen and hydrogen in the comet's coma.

This position was also very near the galactic equator, making it almost impossible to find such an object within the dense concentration of background stars of the Milky Way.  In the fourteen years of looking for planets, Tombaugh looked for motion in 90 million star images.

text: The initial 1949 Meteor was introduced on June 25, 1948, at the same time the Ford Deluxe and Custom series were introduced across North America, and shared the new postwar full-sized Ford bodies, chassis, and powertrains but with unique trim. It used a Mercury grille and was powered by a , 239 CID flathead V8 similar to that used in 1946-53 U.S. Ford passenger cars. Meteor, as well as the Canadian Ford, kept the flathead V8 engine through 1954. The new OHV V8 which US Fords offered beginning in 1954 was not introduced in Canada until the 1955 model year. The following year, Ford of Canada introduced a six-cylinder engine for Canadian Ford and Meteor cars. Meteor models continued to use the Ford body with unique items such as grilles, taillights, and moldings. The 1952-54 Meteors used Mercury instrument panels and dashboards. In mid-1954, some Niagara and Rideau models began using Ford instrument panels and dashes. These cars were named Niagara Special and Rideau Special and were priced around C$67 less than regular Niagaras or Rideaus.

text: The dynamic method is a procedure for the determination of the masses of asteroids.  The procedure gets its name from its use of the Newtonian laws of the dynamics, or motion, of asteroids as they move around the Solar System.  The procedure works by taking multiple position measurements to determine the gravitational deflection caused when two or more asteroids move past each other.  The method relies on the fact that the large number of known asteroids means they will occasionally move past one another at very close distances.  If at least one of the two interacting bodies is large enough, its gravitational influence on the other can reveal its mass.  The accuracy of the determined mass is limited by the precision and timing of the appropriate astrometric observations being made to determine the gravitational deflection caused by a given interaction.

text: Minor planets that have been given a number but not a name keep their provisional designation, e.g. (29075) 1950 DA. Because modern discovery techniques are finding vast numbers of new asteroids, they are increasingly being left unnamed. The earliest discovered to be left unnamed was for a long time (3360) 1981 VA, now 3360 Syrinx; as of September 2008, this distinction is held by (3708). On rare occasions, a small object's provisional designation may become used as a name in itself: the still unnamed  gave its "name" to a group of objects that became known as Classical Kuiper belt objects ("cubewanos").

text: Formal minor planet designations are number–name combinations overseen by the Minor Planet Center, a branch of the IAU. They are used for dwarf planets and small Solar System bodies such as asteroids, but not comets. They are assigned to a body once its orbit is secured, and are unrelated to provisional designations, which are automatically assigned when an object is discovered.

text: Some mainframe games that did not appear in 101 BASIC Computer Games have still had a lasting impact. One such game was Space Travel, developed by Ken Thompson in 1969, which simulates travel in the Solar System. The player flies their ship around a two-dimensional scale model of the solar system with no objectives other than to attempt to land on various planets and moons. The player can move and turn the ship, and adjust the overall speed by adjusting the scale of the simulation. The ship is affected by the single strongest gravitational pull of the astronomical bodies. The game was developed at Bell Labs, and was ported during 1969 from the Multics operating system to the GECOS operating system on the GE 635 computer, and then to the PDP-7 minicomputer. While porting the game to the PDP-7, Thompson developed ideas for his own operating system, which later formed the core of the Unix operating system. Space Travel never spread beyond Bell Labs or had an effect on future games, leaving its primary legacy as part of the original push for the development of Unix.

text: Tyche was a proposed gas giant to be located in the Solar System's Oort cloud. It was first proposed in 1999 by astrophysicists John Matese, Patrick Whitman and Daniel Whitmire of the University of Louisiana at Lafayette. They argued that evidence of Tyche's existence could be seen in a supposed bias in the points of origin for long-period comets. In 2013, Matese and Whitmire re-evaluated the comet data and noted that Tyche, if it existed, would be detectable in the archive of data that was collected by NASA's Wide-field Infrared Survey Explorer (WISE) telescope. In 2014, NASA announced that the WISE survey had ruled out any object with Tyche's characteristics, indicating that Tyche as hypothesized by Matese, Whitman, and Whitmire does not exist.

text: The Galilean moons are the four largest moons of Jupiter—Io, Europa, Ganymede, and Callisto. They were discovered by Galileo Galilei around January 1610 and were the first group of objects found to orbit another planet. Their names derive from the lovers of Zeus. They are among the largest objects in the Solar System with the exception of the Sun and the eight planets, with radii larger than any of the dwarf planets. Ganymede is the largest moon in the Solar System, and is even bigger than the planet Mercury. The three inner moons—Io, Europa, and Ganymede—are in a 4:2:1 orbital resonance with each other.

text: Even planets in more stable orbits of a binary star system would suffer other kinds of problems according to her such as climatic problems. As an example, a planet in a binary star system orbiting the larger star would be drawn closer to its gravitational field, causing the planet to endure heat of great temperatures during this period. As the planet passes its larger star and reaches the orbit of its smaller star, the gravitational field of that star would give the planet more distance from it. The distance (perhaps along with the smaller solar projection of the star) would send the planet into extreme frigid temperatures.

text: Astrochemistry is the study of the abundance and reactions of chemical elements and molecules in the universe, and their interaction with radiation. The discipline is an overlap of astronomy and chemistry.  The word "astrochemistry" may be applied to both the Solar System and the interstellar medium. The study of the abundance of elements and isotope ratios in Solar System objects, such as meteorites, is also called cosmochemistry, while the study of interstellar atoms and molecules and their interaction with radiation is sometimes called molecular astrophysics. The formation, atomic and chemical composition, evolution and fate of molecular gas clouds is of special interest, because it is from these clouds that solar systems form.

text: Like nearly all extrasolar planets discovered prior to 2008, PSR B1620-26 b was originally detected through the Doppler shifts its orbit induces on radiation from the star it orbits (in this case, changes in the apparent pulsation period of the pulsar). In the early 1990s, a group of astronomers led by Donald Backer, who were studying what they thought was a binary pulsar, determined that a third object was needed to explain the observed Doppler shifts. Within a few years, the gravitational effects of the planet on the orbit of the pulsar and white dwarf had been measured, giving an estimate of the mass of the third object that was too small for it to be a star. The conclusion that the third object was a planet was announced by Stephen Thorsett and his collaborators in 1993.

text: KOI-74b is a hot compact object orbiting KOI-74. It was discovered in 2010 by the Kepler Mission and came to attention because of its small size (its radius is only 4.3% of the solar radius) and high temperature of . The orbit of KOI-74b around the main star takes 5.18875 days to complete. Analysis of relativistic boosting of light in the Kepler data indicates that it is likely to be a low mass white dwarf of approximately 0.22 solar masses, resulting from an earlier phase of mass transfer in a binary system when the object underwent its giant phase.

text: In addition to showing how the inner solar system formed, Wetherill's work provided the basis for a model of a giant-impact origin for the Moon and the core of Mercury. It also led to explanations for the isotopic abundances of present-day planetary atmospheres. Recently, Wetherill has shown that Jupiter plays an important role in the evolution of the Solar System; by ejecting comets from the solar system, it offers a protective presence to the inner planets. Wetherill's theoretical work supports discussions on the origins of the Solar System as well as on extrasolar planets.

text: A series of simulations by Gomes et al. start with a Solar System where the giant planets are in a tight orbital configuration.  This configuration is in itself stable, but assuming a rich trans-Neptunian belt, stray transneptunians interacted with these planets, causing them to migrate slowly during a time of several hundred million years. Jupiter is predicted to migrate inward, whereas the other planets go outwards. By this migration, the Solar System became catastrophically unstable when Jupiter and Saturn reached a 2:1 orbital resonance, causing the outer Solar System to reconfigure rapidly to a wide jovian system. As these planets migrated, resonances would be "swept" through the asteroid belt and Kuiper belt. These resonances would increase the orbital eccentricity of the objects, allowing them to enter the inner Solar System and impact with the terrestrial planets.

text: The Apollo 14 Passive Seismic Experiment (PSE) was placed on the lunar surface as part of the Apollo 14 ALSEP package. The PSE was designed to detect vibrations and tilting of the lunar surface and measure changes in gravity at the instrument location. The vibrations are due to internal seismic sources (moonquakes) and external (meteoroids and impacts from the spent S-IVB and LM ascent stages). The primary objective of the experiment was to use these data to determine the internal structure, physical state, and tectonic activity of the Moon. The secondary objectives were to determine the number and mass of meteoroids that strike the Moon and record tidal deformations of the lunar surface.

text: The Greek writer Lucian (ca. 125–after 180 AD) suggests that Pluto's love for his wife gave the ruler of the underworld a special sympathy or insight into lovers parted by death. In one of Lucian's Dialogues of the Dead, Pluto questions Protesilaus, the first Greek hero killed in the Trojan War, who wishes to return to the world of the living. "You are then in love with life?" Pluto asks. "Such lovers we have here in plenty; but they love an object, which none of them can obtain." Protesilaus explains, like an Orpheus in reverse, that he has left behind a young bride whose memory even the Lethe's waters of forgetting have not erased from him. Pluto assures him that death will reunite them someday, but Protesilaus argues that Pluto himself should understand love and its impatience, and reminds the king of his grant to Orpheus and to Alcestis, who took her husband's place in death and then was permitted at the insistence of Heracles to return to him. When Persephone intercedes for the dead warrior, Pluto grants the request at once, though allowing only one day for the reunion.

text: None of these claims has ever been substantiated after more than forty years of observation. It has been surmised, however, that some of these objects—and other alleged intra-Mercurial objects—may exist, being nothing more than previously unknown comets or small asteroids. Today, the search continues for these so-called vulcanoid asteroids, which are thought to exist in the region where Vulcan was once sought. None have been found yet and searches have ruled out any such asteroids larger than about 6 km. Neither SOHO nor STEREO has detected a planet inside the orbit of Mercury.

text: Asteroids are minor planets, especially those of the inner Solar System. The larger ones have also been called planetoids. These terms have historically been applied to any astronomical object orbiting the Sun that did not show the disc of a planet and was not observed to have the characteristics of an active comet. As minor planets in the outer Solar System were discovered and found to have volatile-based surfaces that resemble those of comets, they were often distinguished from asteroids of the asteroid belt. In this article, the term "asteroid" refers to the minor planets of the inner Solar System including those co-orbital with Jupiter.

text: This makes Eris around the same size as Pluto, which is  across. It also indicates an albedo of 0.96, higher than that of any other large body in the Solar System except Enceladus. It is speculated that the high albedo is due to the surface ices being replenished because of temperature fluctuations as Eris's eccentric orbit takes it closer and farther from the Sun.

text: In the end stages of planet formation, a planet (as so defined) will have "cleared the neighbourhood" of its own orbital zone, meaning it has become gravitationally dominant, and there are no other bodies of comparable size other than its satellites or those otherwise under its gravitational influence. A large body that meets the other criteria for a planet but has not cleared its neighbourhood is classified as a dwarf planet. This includes Pluto, which is constrained in its orbit by the gravity of Neptune and shares its orbital neighbourhood with Kuiper belt objects. The IAU's definition does not attach specific numbers or equations to this term, but all the planets have cleared their neighbourhoods to a much greater extent (by orders of magnitude) than any dwarf planet, or any candidate for dwarf planet.

text: There is no official definition of 'cubewano' or 'classical KBO'. However, the terms are normally used to refer to objects free from significant perturbation from Neptune, thereby excluding KBOs in orbital resonance with Neptune (resonant trans-Neptunian objects). The Minor Planet Center (MPC) and the Deep Ecliptic Survey (DES) do not list cubewanos (classical objects) using the same criteria. Many TNOs classified as cubewanos by the MPC are classified as ScatNear (possibly scattered by Neptune) by the DES. Dwarf planet Makemake is such a borderline classical cubewano/scatnear object.  may be an inner cubewano near the plutinos. Furthermore, there is evidence that the Kuiper belt has an 'edge', in that an apparent lack of low-inclination objects beyond 47–49 AU was suspected as early as 1998 and shown with more data in 2001. Consequently, the traditional usage of the terms is based on the orbit’s semi-major axis, and includes objects situated between the 2:3 and 1:2 resonances, that is between 39.4 and 47.8 AU (with exclusion of these resonances and the minor ones in-between).

text: Himalia (  or  ; ) is the largest irregular satellite of Jupiter, the sixth largest overall in size, and only the four Galilean moons of Jupiter have greater mass. It was discovered by Charles Dillon Perrine at the Lick Observatory on 3 December 1904 and is named after the nymph Himalia, who bore three sons of Zeus (the Greek equivalent of Jupiter). It is one of the largest planetary moons in the Solar System not imaged in detail, and the largest not including the moons of Neptune and several trans-Neptunian objects, particularly that of the second-largest-but-most-massive dwarf planet, Eris.

text: Eris is a trans-Neptunian dwarf planet (plutoid). Its orbital characteristics more specifically categorize it as a scattered-disk object (SDO), or a TNO that has been "scattered" from the Kuiper belt into more-distant and unusual orbits following gravitational interactions with Neptune as the Solar System was forming. Although its high orbital inclination is unusual among the known SDOs, theoretical models suggest that objects that were originally near the inner edge of the Kuiper belt were scattered into orbits with higher inclinations than objects from the outer belt. Inner-belt objects are expected to be generally more massive than outer-belt objects, and so astronomers expect to discover more large objects like Eris in high-inclination orbits, which have traditionally been neglected.

text: The International Astronomical Union (IAU) currently recognizes five dwarf planets: , Pluto, , , and . Brown criticizes this official recognition: "A reasonable person might think that this means that there are five known objects in the solar system which fit the IAU definition of dwarf planet, but this reasonable person would be nowhere close to correct."It is suspected that another hundred or so known objects in the Solar System are dwarf planets. Estimates are that up to 200 dwarf planets may be found when the entire region known as the Kuiper belt is explored, and that the number may exceed 10,000 when objects scattered outside the Kuiper belt are considered. Individual astronomers recognize several of these, and in August 2011 Mike Brown published a list of 390 candidate objects, ranging from "nearly certain" to "possible" dwarf planets. Brown currently identifies eleven known objects—the five accepted by the IAU plus , , , ,  and —as "virtually certain", with another dozen highly likely.

text: The primary objective of Pin Bot is to score points by hitting targets and completing simple objectives.  The rules of the game are for the most part identical to those of the pinball machine: The player starts with a lit marker set on Pluto and advances through the solar system by hitting various lit targets.  Reaching a certain flashing checkpoint planet (Saturn, Jupiter or Mars) awards a Special, which in this version lights an Extra Ball.  Reaching the Sun also awards a Special, lighting another Extra Ball.

text: The Crab Nebula was first identified in 1731 by John Bevis. The nebula was independently rediscovered in 1758 by Charles Messier as he was observing a bright comet. Messier catalogued it as the first entry in his catalogue of comet-like objects; in 1757, Alexis Clairaut reexamined the calculations of Edmund Halley and predicted the return of Halley's Comet in late 1758. The exact time of the comet's return required the consideration of perturbations to its orbit caused by planets in the Solar System such as Jupiter, which Clairaut and his two colleagues Jérôme Lalande and Nicole-Reine Lepaute carried out more precisely than Halley, finding that the comet should appear in the constellation of Taurus. It is in searching in vain for the comet that Charles Messier found the Crab nebula, which he at first thought to be Halley's comet. After some observation, noticing that the object that he was observing was not moving across the sky, Messier concluded that the object was not a comet. Messier then realised the usefulness of compiling a catalogue of celestial objects of a cloudy nature, but fixed in the sky, to avoid incorrectly cataloguing them as comets.

text: The jumping-Jupiter scenario specifies an evolution of giant-planet migration described by the Nice model, in which an ice giant (Uranus, Neptune, or an additional Neptune-mass planet) is scattered inward by Saturn and outward by Jupiter, causing the step-wise separation of their orbits. The jumping-Jupiter scenario was proposed by Ramon Brasser, Alessandro Morbidelli, Rodney Gomes, Kleomenis Tsiganis, and Harold Levison after their studies revealed that the smooth divergent migration of Jupiter and Saturn resulted in an inner Solar System significantly different from the current Solar System. The sweeping of secular resonances through the inner Solar System during the migration excited the eccentricities of the terrestrial planets beyond current values and left an asteroid belt with an excessive ratio of high- to low-inclination objects. The step-wise separation of Jupiter and Saturn described in the jumping-Jupiter scenario can allow these resonances to quickly cross the inner Solar System without altering orbits excessively, although the terrestrial planets remain sensitive to its passage. The jumping-Jupiter scenario also results in a number of other differences with the original Nice model. The fraction of lunar impactors from the core of the asteroid belt during the Late Heavy Bombardment is significantly reduced, most of the Jupiter trojans are captured during Jupiter's encounters with the ice giant, as are Jupiter's irregular satellites. In the jumping-Jupiter scenario, the likelihood of preserving four giant planets on orbits resembling their current ones appears to increase if the early Solar System originally contained an additional ice giant, which was later ejected by Jupiter into interstellar space. However, this remains an atypical result, as is the preservation of the current orbits of the terrestrial planets.

text: Lead researcher Ivan Ramirez explained the significance of finding solar siblings in a press release for the University of Texas at which he works. "We want to know where we were born. If we can figure out in what part of the galaxy the Sun formed, we can constrain conditions on the early solar system. That could help us understand why we are here." He also said there was a "small, but not zero" chance that planets with life might orbit solar sibling stars, because during the frequent collisions during planetary formation material might have travelled from one system to another. He said the siblings might be "key candidates" in the search for extraterrestrial life. A scenario for transfer of life by this means might require life or a precursor molecule to be shielded from radiation for millions of years, dormant within an outgoing chunk of planetary debris one meter or more in diameter that is produced by a meteorite impact, until this new meteorite impacts on a different planet. Such an unlikely event might have transferred life from another planet to Earth or vice versa.

text: Pluto is the largest and most-massive member of the Kuiper belt and the largest and the second-most-massive known TNO, surpassed only by Eris in the scattered disc. Originally considered a planet, Pluto's status as part of the Kuiper belt caused it to be reclassified as a dwarf planet in 2006. It is compositionally similar to many other objects of the Kuiper belt, and its orbital period is characteristic of a class of KBOs, known as "plutinos", that share the same 2:3 resonance with Neptune.

text: In India, eri was mostly used for the preparation of winter shawls for men and women. The thermal property of Eri silk makes it a suitable fabric for shawls, jackets, blankets, bed spreads. Dress materials and baby dresses are also made from Eri silk fabric, because of its soft texture and moisture absorbent quality. Nowadays very fine (up to 210-nm) eri spun yarns are available, which enables weavers to weave very fine clothing, including traditional sari dress materials.

text: A second proposal suggests a more complicated origin for the family: that the material ejected in the initial collision instead coalesced into a large moon of Haumea, which gradually increased its distance from Haumea through tidal evolution, and was then later shattered in a second collision, dispersing its shards outwards. This second scenario produces a velocity dispersion of ~190 m/s, considerably closer to the measured ~140 m/s velocity dispersion of the family members; it also avoids the difficulty of the observed ~140 m/s dispersion being much less than the ~900 m/s escape velocity of Haumea.

text: Heinrich Olbers discovered Pallas in 1802, the year after the discovery of Ceres. He proposed that the two objects were the remnants of a destroyed planet. He sent a letter with his proposal to the English astronomer William Herschel, suggesting that a search near the locations where the orbits of Ceres and Pallas intersected might reveal more fragments. These orbital intersections were located in the constellations of Cetus and Virgo. Olbers commenced his search in 1802, and on 29 March 1807 he discovered Vesta in the constellation Virgo—a coincidence, because Ceres, Pallas, and Vesta are not fragments of a larger body. Because the asteroid Juno had been discovered in 1804, this made Vesta the fourth object to be identified in the region that is now known as the asteroid belt. The discovery was announced in a letter addressed to German astronomer Johann H. Schröter dated 31 March. Because Olbers already had credit for discovering a planet (Pallas; at the time, the asteroids were considered to be planets), he gave the honor of naming his new discovery to German mathematician Carl Friedrich Gauss, whose orbital calculations had enabled astronomers to confirm the existence of Ceres, the first asteroid, and who had computed the orbit of the new planet in the remarkably short time of 10 hours. Gauss decided on the Roman virgin goddess of home and hearth, Vesta.

text: The meteorite was formed from nebular dust and gas during the early formation of the Solar System.  It is a "stone" meteorite, as opposed to an "iron," or "stony iron," the other two general classes of meteorite.  Most Allende stones are covered, in part or in whole, by a black, shiny crust created as the stone descended at great speed through the atmosphere as it was falling towards the earth from space.  This causes the exterior of the stone to become very hot, melting it, and forming a glassy "fusion crust."

text: From the Helium isotope abundance data, the cosmic D/H value is estimated to be around 20 ppm which is much lower than the terrestrial D/H ratio of 150 ppm. The enrichment of D/H from the proto-solar reservoir occurs for most of the planets except for Jupiter and Saturn, the massive gaseous planets. The D/H ratios of the atmospheres of Venus and Mars are ~2 × 10 and ~8 × 10 respectively. The D/H ratios of Uranus and Neptune is larger than that of protosolar reservoir by a factor of around 3 due to their Deuterium-rich icy cores. The D/H ratios for comets are much larger than the values for the planets in the solar system with δD value of around 1000‰.

text: Deuterium is destroyed in the interiors of stars faster than it is produced. Other natural processes are thought to produce only an insignificant amount of deuterium. Nearly all deuterium found in nature was produced in the Big Bang 13.8 billion years ago, as the basic or primordial ratio of hydrogen-1 (protium) to deuterium (about 26 atoms of deuterium per million hydrogen atoms) has its origin from that time. This is the ratio found in the gas giant planets, such as Jupiter (see references 2,3 and 4). However, other astronomical bodies are found to have different ratios of deuterium to hydrogen-1. This is thought to be as a result of natural isotope separation processes that occur from solar heating of ices in comets. Like the water-cycle in Earth's weather, such heating processes may enrich deuterium with respect to protium.  The analysis of deuterium/protium ratios in comets found results very similar to the mean ratio in Earth's oceans (156 atoms of deuterium per million hydrogens). This reinforces theories that much of Earth's ocean water is of cometary origin.  The deuterium/protium ratio of the comet 67P/Churyumov-Gerasimenko, as measured by the Rosetta space probe, is about three times that of earth water. This figure is the highest yet measured in a comet.

text: Big Bang

text: 13.8 billion years ago, as the basic or primordial ratio of hydrogen-1 (protium) to deuterium (about 26 atoms of deuterium per million hydrogen atoms) has its origin from that time. This is the ratio found in the gas giant planets, such as Jupiter (see references 2,3 and 4). However, other astronomical bodies are found to have different ratios of deuterium to hydrogen-1. This is thought to be as a result of natural isotope separation processes that occur from solar heating of ices in comets. Like the water-cycle in Earth's weather, such heating processes may enrich deuterium with respect to protium.  The analysis of deuterium/protium ratios in comets found results very similar to the mean ratio in Earth's oceans (156 atoms of deuterium per million hydrogens). This reinforces theories that much of Earth's ocean water is of cometary origin.  The deuterium/protium ratio of the comet 67P/Churyumov-Gerasimenko, as measured by the

text: PLUTO was a materials testing nuclear reactor housed at the Atomic Energy Research Establishment, a former Royal Air Force airfield at Harwell, Oxfordshire in the United Kingdom. It was one of five reactors on the site. The site was selected as the scientific center for research and development of UK's expanding nuclear programs. Designed by the United Kingdom Atomic Energy Authority (UKAEA), the reactor was built by Head Wrightson Processes Ltd, an industrial firm in Teesside, England. PLUTO was one of two high flux reactors; the first, DIDO, was its prototype. PLUTO was the second of three DIDO class reactors to become operational. PLUTO and DIDO were located at Harwell; the third, Dounreay (DMTR) in Caithness, Scotland.The development of multi-purpose type PLUTO reactors gave rise to many countries building their own materials testing reactors based on DIDO's design. On 27 October 1957, the PLUTO reactor was commissioned and operated for thirty three years before decommissioning in 1990.

text: By the beginning of 1930, Tombaugh's search had reached the constellation of Gemini. On 18 February 1930, after searching for nearly a year and examining nearly 2 million stars, Tombaugh discovered a moving object on photographic plates taken on 23 January and 29 January of that year. A lesser-quality photograph taken on January 21 confirmed the movement. Upon confirmation, Tombaugh walked into Slipher's office and declared, "Doctor Slipher, I have found your Planet X." The object lay just six degrees from one of two locations for Planet X  Lowell had suggested; thus it seemed he had at last been vindicated. After the observatory obtained further confirmatory photographs, news of the discovery was telegraphed to the Harvard College Observatory on March 13, 1930. The new object was later precovered on photographs dating back to 19 March 1915. The decision to name the object Pluto was intended in part to honour Percival Lowell, as his initials made up the word's first two letters. After discovering Pluto, Tombaugh continued to search the ecliptic for other distant objects. He found hundreds of  variable stars and asteroids, as well as two comets, but no further planets.

text: Astrologically speaking, Pluto is called "the great renewer", and is considered to represent the part of a person that destroys in order to renew, through bringing buried, but intense needs and drives to the surface, and expressing them, even at the expense of the existing order. A commonly used keyword for Pluto is "transformation". It is associated with power and personal mastery, and the need to cooperate and share with another, if each is not to be destroyed. Pluto governs big business and wealth, mining, surgery and detective work, and any enterprise that involves digging under the surface to bring the truth to light. Pluto is also associated with Tuesday, alongside Mars.

text: In 1980, in his paper On the existence of a comet belt beyond Neptune, Fernández proposed that periodic comets arrived too frequently into the inner Solar System to be accounted for solely by having arrived from the Oort cloud, and that a trans-Neptunian belt of comets at around 50 AU would be required to explain them.  Subsequent computer models by Martin Duncan, Tom Quinn and Scott Tremaine in Canada supported the view, and led eventually to the discovery of the Kuiper belt. Many astronomers, including David Jewitt, who discovered the belt, believe that Fernández deserves more credit than anyone else, including Gerard Kuiper, for predicting its existence.   He has subsequently published many papers on the trans-Neptunian population.

text: Enceladus, a moon of Saturn, has one of the highest known albedos of any body in the Solar System, with 99% of EM radiation reflected. Another notable high-albedo body is Eris, with an albedo of 0.96. Many small objects in the outer Solar System and asteroid belt have low albedos down to about 0.05. A typical comet nucleus has an albedo of 0.04. Such a dark surface is thought to be indicative of a primitive and heavily space weathered surface containing some organic compounds.

The Sun forms a counterbalance to all of the planets, so it is near the barycenter when Jupiter is on one side and the other three jovian planets are diametrically opposite on the other side, but the Sun moves to 2.17 solar radii away from the barycenter when all jovian planets are in line on other side. The orbital angular momenta of the Sun and all non-jovian planets, moons, and small Solar System bodies, as well as the axial rotation momenta of all bodies, including the Sun, total only about 2%.

text: Hygiea is the main member of the Hygiea family and contains almost all the mass  (well over 90%) in this family. It is the largest of the class of dark C-type asteroids that are dominant in the outer asteroid belt—which lie beyond the Kirkwood gap at 2.82 AU. Hygiea appears to have a noticeably oblate spheroid shape, with an average diameter of 444 ± 35 km and a semimajor axis ratio of 1.11. This is much more than for the other objects in the "big four"—2 Pallas, 4 Vesta and the dwarf planet Ceres. Aside from being the smallest of the four, Hygiea, like Ceres, has a relatively low density, which is more comparable to the icy satellites of Jupiter or Saturn than to the terrestrial planets or the stony asteroids.

text: In this initial model the number of planetesimals that would reach the Moon is consistent with the crater record from the LHB. Impacts onto Jupiter's moons are sufficient to trigger Ganymede's differentiation but not Callisto's. However, significant differences with observations have also been identified. The orbital distribution of the surviving asteroid belt has an excess of high inclination objects due to the secular resonances exciting inclinations and also removing low inclination objects. During Jupiter and Saturn's slow approach to the 2:1 resonance leading up to the LHB Mars's eccentricity can reach a level that results in the destabilization of the inner Solar System. The eccentricities of the other terrestrial planets can also be excited beyond current levels by sweeping secular resonances. In the outer Solar System the impacts of icy planetesimals onto Saturn's inner moons are sufficient to vaporize their ice. These issue provided motivations for modifications to the initial Nice model.

text: In a 2009 interview with the Discovery Channel, Mike Brown noted that, while it is not impossible that the Sun has a distant planetary companion, such an object would have to be lying very far from the observed regions of the Solar System to have no detectable gravitational effect on the other planets. A Mars-sized object could lie undetected at 300 AU (10 times the distance of Neptune); a Jupiter-sized object at 30,000 AU. To travel 1000 AU in two years, an object would need to be moving at 2400 km/s – faster than the galactic escape velocity. At that speed, any object would be shot out of the Solar System, and then out of the Milky Way galaxy into intergalactic space.

text: A comet and its dust allow investigation of the Solar System beyond the main planetary orbits. Comets are distinguished by their orbits; long period comets have long elliptical orbits, randomly inclined to the plane of the Solar System, and with periods greater than 200 years. Short period comets are usually inclined less than 30 degrees to the plane of the Solar System, revolve around the Sun in the same counterclockwise direction as the planets orbit, and have periods less than 200 years.

text: In the early 2000s many new, relatively large planetary bodies were found beyond Pluto, and with orbits extending hundreds of AU out past the heliosheath (90–1000 AU). The NASA probe New Horizons may explore this area now that it has performed its Pluto flyby in 2015 (Pluto's orbit ranges from about 29–49 AU). Some of these large objects past Pluto include 136199 , 136108 , 136472 , and 90377 Sedna. Sedna comes as close as 76 AU, but travels out as far as 961 AU at aphelion, and minor planet  goes out past 1060 AU at aphelion. Bodies like these affect how the Solar System is understood, and traverse an area previously only in the domain of interstellar missions or precursor probes. After the discoveries, the area is also in the domain of interplanetary probes; some of the discovered bodies may become targets for exploration missions, an example of which is preliminary work on a probe to Haumea and its moons (at 35–51 AU). Probe mass, power source, and propulsion systems are key technology areas for this type of mission. In addition, a probe beyond 550 AU could use the Sun itself as a gravitational lens to observe targets outside the Solar System, such as planetary systems around other nearby stars, although many challenges to this mission have been noted.

text: The extra-solar environment is chosen by Leinster in order to convey the feeling of an ever-expanding frontier - Sol's own Asteroid Belt has become "tame", as did the rings of Saturn, and the rough adventurous types move further on. (Leinster's  historical model is obviously the recurring Gold Rush of the Nineteenth Century, drawing adventurers in 1840s from the settled East Coast to wild California, and in 1890s from settled California to the wild Klondike.)

text: Estimating the sizes of asteroids from observations is difficult due to their irregular shapes, varying albedo (reflectivity), and small angular diameter. For example, pure C-type asteroids are much darker than most. Asteroids with only one or two axes measured may have a falsely inflated geometric mean diameter if the unknown second and/or third axis is noticeably smaller than the primary axis. Asteroid 16 Psyche has an IRAS diameter of 253 km, yet has a more recent and accurate geometric mean of only 186 km.

text: During its period of migration, Neptune is thought to have captured a large KBO, Triton, which is the only large moon in the Solar System with a retrograde orbit (it orbits opposite to Neptune's rotation). This suggests that, unlike the large moons of Jupiter, Saturn, and Uranus, which are thought to have coalesced from rotating discs of material around their young parent planets, Triton was a fully formed body that was captured from surrounding space. Gravitational capture of an object is not easy: it requires some mechanism to slow down the object enough to be caught by the larger object's gravity. A possible explanation is that Triton was part of a binary when it encountered Neptune. (Many KBOs are members of binaries. See below.) Ejection of the other member of the binary by Neptune could then explain Triton's capture. Triton is only 14% larger than Pluto, and spectral analysis of both worlds shows that their surfaces are largely composed of similar materials, such as methane and carbon monoxide. All this points to the conclusion that Triton was once a KBO that was captured by Neptune during its outward migration.

text: In October 2010, NASA extended the mission by one month with a program called Near-Earth Object WISE (NEOWISE). Due to its success, the program was extended a further three months. The focus was to look for asteroids and comets close to Earth orbit, using the remaining post-cryogenic detection capability (two of four detectors on WISE work without cryogen). In February 2011, NASA announced that NEOWISE had discovered many new objects in the Solar System, including twenty comets. During its primary and extended missions, the spacecraft delivered characterizations of 158,000 minor planets, including more than 35,000 newly discovered objects.

text: Boötes is home to the Quadrantid meteor shower, the most prolific annual meteor shower. It was discovered in January 1835 and named in 1864 by Alexander Hershell. The radiant is located in northern Boötes near Kappa Boötis, in its namesake former constellation of Quadrans Muralis. Quadrantid meteors are dim, but have a peak visible hourly rate of approximately 100 per hour on January 3–4. The zenithal hourly rate of the Quadrantids is approximately 130 meteors per hour at their peak; it is also a very narrow shower. The Quadrantids are notoriously difficult to observe because of a low radiant and often inclement weather. The parent body of the meteor shower has been disputed for decades; however, Peter Jenniskens has proposed 2003 EH, a minor planet, as the parent. 2003 EH may be linked to C/1490 Y, a comet previously thought to be a potential parent body for the Quadrantids. 2003 EH is a short-period comet of the Jupiter family; 500 years ago, it experienced a catastrophic breakup event. It is now dormant. The Quadrantids had notable displays in 1982, 1985, and 2004. Meteors from this shower often appear to have a blue hue and travel at a moderate speed of 41.5–43 kilometers per second.

text: The dust is thought to be generated by collisions among comets and asteroids. Radiation pressure from the star will push the dust particles away into interstellar space over a relatively short timescale. Therefore, the detection of dust indicates continual replenishment by new collisions, and provides strong indirect evidence of the presence of small bodies like comets and asteroids that orbit the parent star. For example, the dust disk around the star tau Ceti indicates that that star has a population of objects analogous to our own Solar System's Kuiper Belt, but at least ten times thicker.

text: As objects increasingly closer in size to Pluto were discovered in the region, it was argued that Pluto should be reclassified as one of the Kuiper belt objects, just as Ceres, Pallas, Juno and Vesta eventually lost their planet status after the discovery of many other asteroids. On July 29, 2005, astronomers at Caltech announced the discovery of a new trans-Neptunian object, Eris, which was substantially more massive than Pluto and the most massive object discovered in the Solar System since Triton in 1846. Its discoverers and the press initially called it the tenth planet, although there was no official consensus at the time on whether to call it a planet. Others in the astronomical community considered the discovery the strongest argument for reclassifying Pluto as a minor planet.

text: The Alpha Monocerotids is a meteor shower with the international acronym AMO active in November, not to be confused with the December Monocerotids, international acronym MON. The swarm is visible every year from 15 to 25 November; its peak occurs on 21 or 22 November. The speed of its meteors is 65 km/s. Normally it has a low Zenithal Hourly Rate (ZHR), but occasionally it produces remarkable meteor storms that last less than an hour: such outbursts were observed in 1925, 1935, 1985, and 1995. Peter Jenniskens predicted the 1995 return based on the hypothesis that these outbursts were caused by the dust trail of a long period comet occasionally wandering in Earth's path due to planetary perturbations. During observations in southern Spain, assisted by a team of observers of the Dutch Meteor Society, Jenniskens confirmed that the meteoroids were moving in a long-period comet orbit. The outburst of 1995 allowed researchers to determine the exact radiant of the swarm and the solar longitude of its peak as well as to confirm the brevity of Alpha Monocerotids outbursts as less than one hour. The parent body, probably a long-period comet, is unknown.

text: Oort cloud comets are continually perturbed by their environment. A non-negligible fraction leaves the Solar System or finds its way into the inner system. It should therefore have been depleted long ago, but it has not. The Hills cloud theory addresses the longevity of the Oort cloud by postulating a densely populated inner Oort region. Objects ejected from the Hills cloud are likely to end up in the classical Oort cloud region, maintaining the Oort cloud. It is likely that the Hills cloud is the largest concentration of comets in the whole Solar System.

text: Previously, when applying the alternative Pb-Pb ischron diagram, the U/U isotope ratios were assumed to be invariant among meteoritic material. However, it has been shown that U/U ratios are variable among meteoritic material. To accommodate this, U-corrected Pb-Pb dating analysis is used to generate ages for the oldest solid material in the solar system using a revised U/U value of 137.786 ± 0.013 to represent the mean U/U isotope ratio bulk inner solar system materials.

text: From 1992 onward, many bodies were discovered orbiting in the same area as Pluto, showing that Pluto is part of a population of objects called the Kuiper belt. This made its official status as a planet controversial, with many questioning whether Pluto should be considered together with or separately from its surrounding population. Museum and planetarium directors occasionally created controversy by omitting Pluto from planetary models of the Solar System. The Hayden Planetarium reopened—in February 2000, after renovation—with a model of only eight planets, which made headlines almost a year later.

text: While the first telescope has been proposed for use as the basis for WFIRST, NASA currently does not have plans or funding for the usage of the second. Astronomers have begun to study possible additional uses, and NASA is considering dozens of proposals; the only prohibition is Earth observation, a condition of the NRO donation. Possibilities include observing Earth's aurora and ionosphere, or asteroids and other faint objects within the solar system. NASA has also suggested that the telescope could be sent to Mars, photographing the surface with a resolution about four times finer than the current Mars Reconnaissance Orbiter's HiRISE instrument. From Martian orbit the telescope could also view the outer Solar System and the asteroid belt.

text: Acquiring a larger sample of such objects would help in determining which scenario is most likely. "I call Sedna a fossil record of the earliest Solar System", said Brown in 2006. "Eventually, when other fossil records are found, Sedna will help tell us how the Sun formed and the number of stars that were close to the Sun when it formed." A 2007–2008 survey by Brown, Rabinowitz and Megan Schwamb attempted to locate another member of Sedna's hypothetical population. Although the survey was sensitive to movement out to 1,000 AU and discovered the likely dwarf planet , it detected no new sednoid. Subsequent simulations incorporating the new data suggested about 40 Sedna-sized objects probably exist in this region, with the brightest being about Eris's magnitude (−1.0).

text: In a world of fantasy far away, a shower of meteorites called Starfall dominates a time in history. The meteorites lie about everywhere pulsing with radioactive power which the people of the land scramble to exploit. Of the people only three professions had the power to exploit the radioactive stones; Mages, Mageslayers, and Lorethanes. The Mages, in their hungry studies of the meteorites, gained knowledge of the use of the stones and gained terrible power. Consumed by their lust for the power of the stones, they dominated over all.

text: When found, asteroids were seen as a class of objects distinct from comets, and there was no unified term for the two until "small Solar System body" was coined in 2006. The main difference between an asteroid and a comet is that a comet shows a coma due to sublimation of near surface ices by solar radiation. A few objects have ended up being dual-listed because they were first classified as minor planets but later showed evidence of cometary activity. Conversely, some (perhaps all) comets are eventually depleted of their surface volatile ices and become asteroid-like. A further distinction is that comets typically have more eccentric orbits than most asteroids; most "asteroids" with notably eccentric orbits are probably dormant or extinct comets.

text: Oort cloud comets are constantly disturbed by their surroundings and distant objects. A significant number either leave the Solar System or go much closer to the Sun. The Oort cloud should therefore have broken apart long ago, but it still remains intact. The Hills cloud theory could provide an explanation; JG Hills and other scientists suggest that it could replenish the comets in the outer Oort cloud.

text: Conrail began operations on the Erie Lackawanna and other Northeastern rail lines on April 1, 1976. The Erie Lackawanna mainline west of Marion, Ohio, was not conveyed to Conrail because of the Erie Lackawanna's 11th hour entry into the Final System Plan. The ownership of this line remained with the Erie Lackawanna Estate, which was a holding company to which all of the railroad's outstanding debt was  transferred. However, since all locomotives and rolling stock were conveyed to Conrail, Conrail was responsible for continuing freight service to customers along the Erie Lackawanna mainline. The condition of this service was only until a suitable short line could assume operations. Conrail's local freight service lasted from April 1976 until early 1977 when Erie Western was formed and began operations.

text: The GUI builder included a drag-and-drop based system for constructing visual objects. SK8 did not have traditional "screens"; it used an invisible "Stage" object that served as the background for managing events and visual objects. One interesting aspect was that no windows, in the traditional sense, were needed or expected to display anything. In fact, any visual object could have window-like behavior (through its drag-and-drop and other smart properties).  SK8 did, however, include a system for editing and programming complete menu bars, a feature that HyperCard lacked. Another oft-requested feature from HyperCard was a media editor, which allowed Macintosh resources to be moved in and out of the project. SK8 built this functionality into the IDE. Other components of the system included an online documentation system, lists of systemwide objects and commands, and the code editor and debugger windows.

text: Although meteorites fall uniformly across the globe they do not typically remain on the surface in areas with a large amount of yearly rainfall. If a newly fallen meteorite is not recovered within a few months it is likely to be buried with alluvium or covered by plant growth.  Some arctic and desert regions have proven to be well-suited to preserving meteorites, and can provide excellent surfaces for hunting visually.

text: The Belt Community: Being as the asteroid belt is ungovernably large, the Belt community consists of widely spread independent and corporate mining operations, with Ceres at its core as the primary trading post. Although conventional law enforcement throughout the belt is impossible, Ceres itself is governed under the just (if not heavy-handed) watch of the Autocrat. Once plagued by rock wars (vicious skirmishes which typically arose due to disputes over mining rights), the death penalty has been frequently employed to keep the population in check. Although the secrets of the Autocrat are closely guarded, the Belt Community has developed a device called the Core cracker, and quite seriously offered to blow up the planet Mercury both to create a second asteroid belt and assist VISOR in the terraforming of Venus.

text: Contrary to popular imagery, the asteroid belt is mostly empty. The asteroids are spread over such a large volume that it would be improbable to reach an asteroid without aiming carefully. Nonetheless, hundreds of thousands of asteroids are currently known, and the total number ranges in the millions or more, depending on the lower size cutoff. Over 200 asteroids are known to be larger than 100 km, and a survey in the infrared wavelengths has shown that the asteroid belt has 0.7–1.7 million asteroids with a diameter of 1 km or more. The apparent magnitudes of most of the known asteroids are 11–19, with the median at about 16.

Makemake follows an orbit very similar to that of : highly inclined at 29° and a moderate eccentricity of about 0.16. Nevertheless, Makemake's orbit is slightly farther from the Sun in terms of both the semi-major axis and perihelion. Its orbital period is nearly 310 years, more than Pluto's 248 years and Haumea's 283 years. Both Makemake and Haumea are currently far from the ecliptic—the angular distance is almost 29°. Makemake is approaching its 2033 aphelion, whereas Haumea passed its aphelion in early 1992.

text: The dwarf planet Pluto has five moons. Its largest moon Charon, named after the ferryman who took souls across the River Styx, is more than half as large as Pluto itself, and large enough to orbit a point outside Pluto's surface. In effect, each orbits the other, forming a binary system informally referred to as a double-dwarf-planet. Pluto's four  other moons, Nix, Hydra,  Kerberos and Styx are  far smaller and orbit the Pluto–Charon system.

text: Despite its vast extent, the collective mass of the Kuiper belt is relatively low. The total mass is estimated to range between 1/25 and 1/10 the mass of the Earth. Conversely, models of the Solar System's formation predict a collective mass for the Kuiper belt of 30 Earth masses. This missing >99% of the mass can hardly be dismissed, because it is required for the accretion of any KBOs larger than  in diameter. If the Kuiper belt had always had its current low density these large objects simply could not have formed by the collision and mergers of smaller planetesimals. Moreover, the eccentricity and inclination of current orbits makes the encounters quite "violent" resulting in destruction rather than accretion. It appears that either the current residents of the Kuiper belt have been created closer to the Sun or some mechanism dispersed the original mass. Neptune's current influence is too weak to explain such a massive "vacuuming", though the Nice model proposes that it could have been the cause of mass removal in the past. Although the question remains open, the conjectures vary from a passing star scenario to grinding of smaller objects, via collisions, into dust small enough to be affected by solar radiation. The extent of mass loss by collisional grinding, however, is limited by the presence of loosely bound binaries in the cold disk, which are likely to be disrupted in collisions.

text: Recently, Peter Jenniskens has argued that most of our short-period meteor showers are not from the normal water vapor drag of active comets, but the product of infrequent disintegrations, when large chunks break off a mostly dormant comet. Examples are the Quadrantids and Geminids, which originated from a breakup of asteroid-looking objects, 2003 EH1 and 3200 Phaethon, respectively, about 500 and 1000 years ago. The fragments tend to fall apart quickly into dust, sand, and pebbles, and spread out along the orbit of the comet to form a dense meteoroid stream, which subsequently evolves into Earth's path.

text: Planetesimals and larger bodies are traditionally thought to have formed via a hierarchical accretion, the formation of large objects via the collision and mergers of small objects. This process begins with the collision of dust due to Brownian motion producing larger aggregates held together by van der Waals forces. The aggregates settle toward the mid-plane of the disk and collide due to gas turbulence forming pebbles and larger objects. Further collisions and mergers eventually yield planetesimals 1–10 km in diameter held together by self-gravity. The growth of the largest planetesimals then accelerates, as gravitational focusing increases their effective cross-section, resulting in runaway accretion forming the larger asteroids. Later, gravitational scattering by the larger objects excites relative motions, causing a transition to slower oligarchic accretion that ends with the formation of planetary embryos. In the outer Solar System the planetary embryos grow large enough to accrete gas, forming the giant planets. In the inner Solar System the orbits of the planetary embryos become unstable, leading to giant impacts and the formation of the terrestrial planets.

text: In reality asteroids, even in the asteroid belt, are spaced extremely far apart. Proto-planets in the process of formation and planetary rings may look like that, but the Sun's asteroid belt does not. (The asteroid belt in the HD 69830 system may, however.) The asteroids are spread over such a high volume that it would be highly improbable even to pass close to a random asteroid. For example, the numerous space probes sent to the outer solar system, just across the main asteroid belt, have never had any problems, and asteroid rendezvous missions have elaborate targeting procedures. The movie 2001: A Space Odyssey is unusual in that it does portray realistically the ship's "encounter" with a lone asteroid pair.

text: A granular material is a conglomeration of discrete solid, macroscopic particles characterized by a loss of energy whenever the particles interact (the most common example would be friction when grains collide). The constituents that compose granular material must be large enough such that they are not subject to thermal motion fluctuations. Thus, the lower size limit for grains in granular material is about 1 µm. On the upper size limit, the physics of granular materials may be applied to ice floes where the individual grains are icebergs and to asteroid belts of the Solar System with individual grains being asteroids.

text: Zinner's PhD research was in high energy physics. He subsequently studied the effects that the environment within our solar system would have on the moon and the parent bodies of meteors, using nuclear particle tracks, micrometeoid craters, and elements in the solar wind. His later research was focused on the information contained in presolar grains carried by early meteorites. These grains were formed in atmospheres and explosions of stars outside of our solar system, and they can provide information about the history of stellar nucleosynthesis and the formation of the solar system.

text: Pluto is a member of the race of immortals known as the gods of Olympus. Among his race, his superhuman strength is equaled only by Neptune and Ares, and is exceeded only by Zeus and Hercules. Pluto's body is also virtually tireless, granting him almost limitless stamina. Pluto has proven capable of withstanding powerful impact forces, temperature extremes, and powerful energy blasts all without sustaining damage. Like all other members of his race, Pluto is immortal in the sense that he is immune to the effects of aging. He hasn't aged since reaching adulthood and is also immune to all known diseases. It would take damage that severely discorporated his body to cause his physical death. He is able to recover from damage with a greater speed and extent than most other members of his race.

text: Spectral analysis of Makemake's surface revealed that methane must be present in the form of large grains at least one centimetre in size. In addition to methane, large amounts of ethane and tholins as well as smaller amounts of ethylene, acetylene and high-mass alkanes (like propane) may be present, most likely created by photolysis of methane by solar radiation. The tholins are probably responsible for the red color of the visible spectrum. Although evidence exists for the presence of nitrogen ice on its surface, at least mixed with other ices, there is nowhere near the same level of nitrogen as on Pluto and Triton, where it composes more than 98 percent of the crust. The relative lack of nitrogen ice suggests that its supply of nitrogen has somehow been depleted over the age of the Solar System.

text: The main component of the atmosphere of Pluto is nitrogen. Content of methane, according to measurements by New Horizons, is 0.25%. For carbon monoxide, the Earth-based estimates are  (2010) and  (2015). Under influence of high-energy cosmic radiation, these gases react to form more complex compounds (not volatile at Pluto's surface temperatures), including ethane (CH), ethylene (CH), acetylene (CH), heavier hydrocarbons and nitriles and hydrogen cyanide (HCN) (amount of ethylene is about 0.0001%, and amount of acetylene is about 0.0003%). These compounds slowly precipitate on the surface. Probably, they also include tholins, which are responsible for the brown color of Pluto (like some other bodies in the outer solar system).

text: 38628 Huya is a trans-Neptunian object (TNO). It is a plutino, being in a 2:3 mean-motion resonance with Neptune. It has a diameter of 458.0±9.2 km, and it is possibly a dwarf planet (icy trans-Neptunian objects with a diameter above around  are expected to be spherical), although the IAU has never classified it as such. Light-curve-amplitude analysis shows only small deviations, suggesting that Huya is likely a spheroid with small albedo spots. As of 2010, astronomer Gonzalo Tancredi thought that Huya was very probably a dwarf planet.

text: Pluto's true place in the Solar System began to reveal itself only in 1992, when astronomers began to find small icy objects beyond Neptune that were similar to Pluto not only in orbit but also in size and composition. This trans-Neptunian population is thought to be the source of many short-period comets. Pluto is now known to be the largest member of the Kuiper belt, a stable belt of objects located between 30 and 50 AU from the Sun. As of 2011, surveys of the Kuiper belt to magnitude 21 were nearly complete and any remaining Pluto-sized objects are expected to be beyond 100 AU from the Sun. Like other Kuiper-belt objects (KBOs), Pluto shares features with comets; for example, the solar wind is gradually blowing Pluto's surface into space. It has been claimed that if Pluto were placed as near to the Sun as Earth, it would develop a tail, as comets do. This claim has been disputed with the argument that Pluto's escape velocity is too high for this to happen.

text: Mortified that he had previously presented the device and forgotten about it, Farnsworth hastily begins drawing on a napkin. He presents the drawing, which depicts both a Smelloscope, a device that allows people to smell distant cosmic objects, and a doodle of himself as a cowboy. As the audience laughs he sweats and wipes the napkin on his head by accident, blurring the picture. Wernstrom announces that the invention deserves "the worst grade imaginable: an A-minus-minus." Back at Planet Express, Farnsworth invites everybody to see the Smelloscope that he had constructed last year and also forgotten about. Fry begins smelling Jupiter, Saturn, and other objects around the solar system and quickly discovers the smelliest object in the universe. After calculating its trajectory, Farnsworth announces that the object will collide with New New York City in 72 hours, reducing it to a "stinky crater" (Bender immediately starts looting at this news).

answers: Pluto

text: His research interests focus on the chemistry and mineralogy of asteroids and comets as determined by in situ laboratory analyses and spacecraft observations. This work is important for constraining the chemistry of the solar nebula, understanding the origin of complex organic molecules in the early Solar System, and constraining the initial chemical inventories of the terrestrial planets. He is an expert in the analysis of extraterrestrial materials. In particular, he uses inductively coupled plasma mass spectrometry (ICP-MS), scanning electron microscopy (SEM), transmission electron microscopy (TEM), electron microprobe analysis (EPMA), and X-ray diffraction (XRD) to study meteorites, lunar samples, and particles returned by the Stardust mission. Lauretta is known for his experimental work on the formation of iron-bearing sulfides in the solar nebula. He also worked on the cosmochemical behavior of various elements, such as mercury, boron and beryllium in meteorites. Asteroid 5819 Lauretta was named in his honor. He is currently serving as the Principal investigator on NASA's OSIRIS-REx mission to return 60 g of regolith from carbonaceous asteroid 101955 Bennu.

text: By studying observations taken by the Hipparcos astrometric mission, a group of scientists proposed that the planet has an inclination of 179.9° (almost exactly face-on) and a mass of 196 Jupiters. If that was the case, the planet would be a red dwarf instead. However, the data was anything but conclusive, and statistically it is extremely unlikely to lie in such a position. But because the inclination is unknown, so is the true mass of the planet. Still, it is very probable that the object is a true planet.

text: If a comet is traveling fast enough, it may leave the Solar System. Such comets follow the open path of a hyperpola, and as such they are called hyperbolic comets. To date, comets are only known to be ejected by interacting with another object in the Solar System, such as Jupiter. An example of this is thought to be Comet C/1980 E1, which was shifted from a predicted orbit of 7.1 million years around the Sun, to a hyperbolic trajectory, after a 1980 close pass by the planet Jupiter.

text: Comets have very different values of eccentricity. Periodic comets have eccentricities mostly between 0.2 and 0.7, but some of them have highly eccentric elliptical orbits with eccentricities just below 1, for example, Halley's Comet has a value of 0.967. Non-periodic comets follow near-parabolic orbits and thus have eccentricities even closer to 1. Examples include Comet Hale–Bopp with a value of 0.995 and comet C/2006 P1 (McNaught) with a value of . As Hale–Bopp's value is less than 1, its orbit is elliptical and it will in fact return. Comet McNaught has a hyperbolic orbit while within the influence of the planets, but is still bound to the Sun with an orbital period of about 10 years. As of a 2010 Epoch, Comet C/1980 E1 has the largest eccentricity of any known hyperbolic comet with an eccentricity of 1.057, and will leave the Solar System indefinitely.

text: The rotation and amplitude of Haumea's light curve place strong constraints on its composition. If Haumea had a low density like Pluto, with a thick mantle of ice over a small rocky core, its rapid rotation would have elongated it to a greater extent than the fluctuations in its brightness allow. Such considerations constrain its density to a range of 2.6–3.3 g/cm. By comparison, the Moon, which is rocky, has a density of 3.3 g/cm, whereas Pluto, which is typical of icy objects in the Kuiper belt, has a density of 1.86 g/cm. Haumea's possible density covers the values for silicate minerals such as olivine and pyroxene, which make up many of the rocky objects in the Solar System. This suggests that the bulk of Haumea is rock covered with a relatively thin layer of ice. A thick ice mantle more typical of Kuiper belt objects may have been blasted off during the impact that formed the Haumean collisional family.

text: Planetesimal accretion could reproduce the size distribution of the asteroids if it began with 100 meter planetesimals. In this model the collisional dampening and gas drag dynamically cool the disk and the bend in the size distribution is caused by a transition between growth regimes. This however require a low level of turbulence in the gas and some mechanism for the formation of 100 meter planetesimals. Size dependent clearing of planetesimals due to secular resonance sweeping could also remove small bodies creating a break in the size distribution of asteroids. As secular resonances swept inward through the asteroid belt as the gas disk dissipated they would excite the eccentricities of the planetesimals. As their eccentricities were damped due to gas drag and tidal interaction with the disk the largest and smallest objects would be lost as their semi-major axes shrank leaving behind the intermediate sized planetesimals.

text: However, only two of these bodies, Ceres and Pluto, have been observed in enough detail to demonstrate that they actually fit the IAU's definition. The IAU accepted Eris as a dwarf planet because it is more massive than Pluto. They subsequently decided that unnamed trans-Neptunian objects with an absolute magnitude brighter than +1 (and hence a diameter of ≥838 km assuming a geometric albedo of ≤1) are to be named under the assumption that they are dwarf planets. The only two such objects known at the time, Makemake and Haumea, went through this naming procedure and were declared to be dwarf planets. The question of whether other likely objects are dwarf planets has never been addressed by the IAU.

text: The inner Solar System is the region comprising the terrestrial planets and the asteroid belt. Composed mainly of silicates and metals, the objects of the inner Solar System are relatively close to the Sun; the radius of this entire region is less than the distance between the orbits of Jupiter and Saturn. This region is also within the frost line, which is a little less than 5 AU (about 700 million km) from the Sun.

text: By happenstance, one of the asteroid explorers enters a ship and hits a button, activating the vehicle and sending him on a thirty-day journey to another solar system. Upon his return, the Gateway Corporation decides to allow explorers (called Prospectors) to take trips on the mostly still-functioning ships. Prospectors who find valuable materials or make discoveries are rewarded with substantial bonuses. Ships on the asteroids come in three sizes and are defined as a "one", "three", or "five" based upon the number of passengers that they can (for the most part uncomfortably) carry. Not every vehicle returns and there are other great hazards to the explorers.

text: Some sixty years after the discovery of Pluto, a large number of large trans-Neptunian objects began to be discovered. Under the criteria of classifying these Kuiper belt objects (KBOs), it became dubious whether Pluto would have been considered a planet had it been discovered in the 1990s. Its mass is now known to be much smaller than once thought and, with the discovery of Eris, it is simply one of the two largest known trans-Neptunian objects. In 2006, Pluto was therefore reclassified into a different class of astronomical bodies known as dwarf planets, along with Eris and others.

text: 2060 Chiron, also known as 95P/Chiron, is a minor planet in the outer Solar System, orbiting the Sun between Saturn and Uranus. Discovered in 1977 by Charles T. Kowal (precovery images have been found as far back as 1895), it was the first-identified member of a new class of objects now known as centaurs—bodies orbiting between the asteroid belt and the Kuiper belt. Besides the four giant planets, Chiron and 10199 Chariklo, also a centaur, are the only other bodies in the Solar System known to have rings.

text: On December 28, 2004, Mike Brown and his team discovered Haumea on images they had taken with the 1.3 m SMARTS Telescope at the Palomar Observatory in the United States on May 6, 2004, while looking for what he hoped would be the tenth planet. The Caltech discovery team used the nickname "Santa" among themselves, because they had discovered Haumea on December 28, 2004, just after Christmas. However, it was clearly too small to be a planet, because it was significantly smaller than Pluto, and Brown did not announce the discovery. Instead he kept it under wraps, along with several other large trans-Neptunian objects (TNOs), pending additional observation to better determine their natures. When his team discovered Haumea's moons, they realized that Haumea was more rocky than other TNOs, and that its moons were mostly ice. They then discovered a small family of nearby icy TNOs, and concluded that these were remnants of Haumea's icy mantle, which had been blasted off by a collision. On July 7, 2005, while he was finishing the paper describing the discovery, Brown's daughter Lilah was born, which delayed the announcement further. On July 20, the Caltech team published an online abstract of a report intended to announce the discovery at a conference the following September. In this Haumea was given the code K40506A.

text: In 1972, Spacecraft Pioneer 10 took the ID card of mankind into the cosmos. A gold plated aluminum plate that indicates where humankind is located in the Universe, presents the outlook of the man and woman, and contains other information. 18 years later, a plate was found on the shore of the Malaga Island, similar to the one we sent into the cosmos but containing new marks on it. It was carried into a safe place and put under examination. Though hard to believe that we received an answer of any civilization may exist in the cosmos: however, the original illustration of Universe, of solar system, of man  were cancelled on the plate and substituted with abstract new illustrations. Made by anyone, the meaning of these changes was evident: our Universe in the reality is not the Universe, but something else. Solar system is not a solar system, but somewhat else. Man is not man, but instead some sort of other creature. But what does this statement more precisely mean? This is what the author searches in this movie, turning back to the ancient centuries to understand and explain the message.

text: Protostars with masses less than roughly  never reach temperatures high enough for nuclear fusion of hydrogen to begin. These are known as brown dwarfs. The International Astronomical Union defines brown dwarfs as stars massive enough to fuse deuterium at some point in their lives (13 Jupiter masses (), 2.5 × 10 kg, or ). Objects smaller than  are classified as sub-brown dwarfs (but if they orbit around another stellar object they are classified as planets). Both types, deuterium-burning and not, shine dimly and die away slowly, cooling gradually over hundreds of millions of years.

text: Dwarf planets, such as Ceres and Pluto, and large small Solar System bodies are similar to terrestrial planets in the fact that they do have a solid surface, but are, on average, composed of more icy materials (Ceres and Pluto have densities 2.17 and 1.87 g cm, respectively, and Haumea's density is similar to Pallas's 2.8 g cm). The Earth's Moon has a density of 3.4 g cm and Jupiter's satellite, Europa, 3.013 g cm; other satellites typically have densities less than 2 g cm.

text: In the immediate aftermath of the object's discovery, there was much discussion as to whether it could be termed a "tenth planet". NASA even put out a press release describing it as such. However, acceptance of Eris as the tenth planet implicitly demanded a definition of planet that set Pluto as an arbitrary minimum size. Many astronomers, claiming that the definition of planet was of little scientific importance, preferred to recognise Pluto's historical identity as a planet by "grandfathering" it into the planet list.

text: Much of the game takes place in space, with the player flying a ship from a third-person overhead perspective. The player has the option of engaging in both combat and trade. Players are able to fly through hundreds of star systems, which are connected to each other by hyperlinks. Ships travel between star systems along the hyperlinks by engaging their hyperdrive, a form of faster-than-light travel. In Nova, wormholes or hypergates may also be utilized for instantaneous travel. Most systems contain stellar objects such as planets and space stations. Players can land on these objects, where they may be given the option to trade, gain missions, and purchase new spaceships or add-on outfits for their current spaceship. The plot is advanced through missions available from facilities on planets as well as NPCs flying through space. Players can choose which missions to follow and which governments to form a good relationship with or to be entirely neutral. They can choose to be a trader or a mercenary or an asteroid miner among a number of things or a combination of several.

text: After the discovery of Pluto and Charon, no more trans-Neptunian objects (TNOs) were found until  in 1992. Since then, thousands of such objects have been discovered. Most are now recognized as part of the Kuiper belt, a swarm of icy bodies left over from the Solar System's formation that orbit near the ecliptic plane just beyond Neptune. Though none were as large as Pluto, some of these distant trans-Neptunian objects, such as Sedna, were initially described in the media as "new planets".

text: Almost immediately, some astronomers questioned Pluto's status as a planet. Barely a month after its discovery was announced, on 14 April 1930, in an article in the New York Times, Armin O. Leuschner suggested that Pluto's dimness and high orbital eccentricity made it more similar to an asteroid or comet: "The Lowell result confirms the possible high eccentricity announced by us on April 5. Among the possibilities are a large asteroid greatly disturbed in its orbit by close approach to a major planet such as Jupiter, or it may be one of many long-period planetary objects yet to be discovered, or a bright cometary object." In that same article, Harvard Observatory director Harlow Shapley wrote that Pluto was a "member of the Solar System not comparable with known asteroids and comets, and perhaps of greater importance to cosmogony than would be another major planet beyond Neptune." In 1931, using a mathematical formula, Ernest W. Brown asserted (in agreement with E. C. Bower), that the presumed irregularities in the orbit of Uranus could not be due to the gravitational effect of a more distant planet, and thus that Lowell's supposed prediction was "purely accidental".

text: However, following the discovery of asteroids below 10 meters in size, Rubin and Grossman in a 2010 paper revised the previous definition of meteoroid to objects between 10 µm and 1 meter in size in order to maintain the distinction between asteroids and meteoroids. The smallest asteroids discovered (based on absolute magnitude H) are  with H = 33.2 and  with H = 32.1 both with an estimated size of about 1 meter.

text: As meteoroids are heated during atmospheric entry, their surfaces melt and experience ablation. They can be sculpted into various shapes during this process, sometimes resulting in shallow thumbprint-like indentations on their surfaces called regmaglypts. If the meteoroid maintains a fixed orientation for some time, without tumbling, it may develop a conical "nose cone" or "heat shield" shape. As it decelerates, eventually the molten surface layer solidifies into a thin fusion crust, which on most meteorites is black (on some achondrites, the fusion crust may be very light colored). On stony meteorites, the heat-affected zone is at most a few mm deep; in iron meteorites, which are more thermally conductive, the structure of the metal may be affected by heat up to  below the surface. Reports vary; some meteorites are reported to be "burning hot to the touch" upon landing, while others are alleged to have been cold enough to condense water and form a frost. Meteorites from multiple falls, such as Bjurbole, Tagish Lake, and Buzzard Coulee, have been found having fallen on lake and sea ice, perhaps suggesting that they were not hot when they fell.

text: An interstellar comet is a comet (or exocomet) located in interstellar space, and not gravitationally bound to a star. Besides known comets within the Solar System, or known extrasolar comets, no interstellar comet, not gravitationally bound to a star, has been conclusively identified. Nonetheless, such comets are conjectured to exist: gravitational scattering by planets and passing stars has ejected many Oort cloud comets from the Solar System, and the likelihood of similar processes in extrasolar planetary systems suggests the existence of a large population of unbound cometary bodies. At present, an interstellar comet can only be detected if it passes through the Solar System, and could be distinguished from an Oort cloud comet by its strongly hyperbolic trajectory (indicating that it is not gravitationally bound to the Sun). Comets with weakly hyperbolic trajectories have been observed, but the trajectories of these comets are consistent with having been knocked loose from the Oort cloud and do not indicate an origin in interstellar space. The most eccentric known comet, C/1980 E1, only has an eccentricity of 1.057, far less eccentric than an interstellar comet would be expected to be.

text: The asteroid belt, which lies between the orbits of Mars and Jupiter, mostly contains objects composed, like the terrestrial planets, of rock and metal. Beyond Neptune's orbit lie the Kuiper belt and scattered disc, which are populations of trans-Neptunian objects composed mostly of ices, and beyond them a newly discovered population of sednoids. Within these populations are several dozen to possibly tens of thousands of objects large enough that they have been rounded by their own gravity. Such objects are categorized as dwarf planets. Identified dwarf planets include the asteroid Ceres and the trans-Neptunian objects Pluto and Eris. In addition to these two regions, various other small-body populations, including comets, centaurs and interplanetary dust clouds, freely travel between regions. Six of the planets, at least four of the dwarf planets, and many of the smaller bodies are orbited by natural satellites, usually termed "moons" after the Moon. Each of the outer planets is encircled by planetary rings of dust and other small objects.

text: Their search was undertaken because hitherto there was no known radioactive isotope of Al that might be useful as a tracer. Theoretical considerations suggested that a state of Al should exist. The life time of Al (  ) was not then known (10-10 yr.) The search for Al took place over many years, long after the discovery of extinct  I (  by Reynolds (1960, Phys. Rev. letters v 4, p 8) which showed that contribution from stellar sources formed ~10 years before the Sun had contributed to the solar system mix. The asteroidal materials that provide meteorite samples were long known to be from the early solar system. Analysis of Ne in some meteorites showed that they had a widely variable isotopic composition. Then Black found that essentially pure Ne was one of the Ne components present which pointed to an extra solar origin of dust from red giant stars. Eberhardt  found that the material obtained by essentially chemically destroying the meteorite matrix resulted in a colloidal sludge residue which contained almost pure Ne. This supported the idea that presolar dust grains were present in the sludge from the meteorite.

text: A planetary system is a set of gravitationally bound non-stellar objects in orbit around a star or star system. Generally speaking, systems with one or more planets constitute a planetary system, although such systems may also consist of bodies such as dwarf planets, asteroids, natural satellites, meteoroids, comets, planetesimals and circumstellar disks. The Sun together with its planetary system, which includes Earth, is known as the Solar System. The term exoplanetary system is sometimes used in reference to other planetary systems.

text: An impact event is a  collision between astronomical objects causing measurable effects. Impact events have physical consequences and have been found to regularly occur in planetary systems, though the most frequent involve asteroids, comets or meteoroids and have minimal impact. When large objects impact terrestrial planets like the Earth, there can be significant physical and biospheric consequences, though atmospheres mitigate many surface impacts through atmospheric entry. Impact craters and structures are dominant landforms on many of the Solar System's solid objects and present the strongest empirical evidence for their frequency and scale.

text: forms a binary system with another object with the IAU provisional designation : the first trans-Neptunian binary to be discovered since Pluto, and one of the most symmetrical binaries known in the Solar System. The two bodies are very close in size, with a diameter ratio of 1.2 and a mass ratio of 1.74, assuming similar surfaces and densities. Their orbital period is approximately 570 days, and they orbit at a distance of approximately 4000 km (closest approach) to 40,000 km, with a semi-major axis of about 22,000 km. Their diameters are likely to be in the 100–150 km range, assuming a density of 1–2 g/cm³. Their combined mass is 1/6000th that of the Pluto–Charon system.

text: The smaller inner moon of the dwarf planet Haumea, Namaka, is one tenth the mass of the larger outer moon, Hiiaka. Namaka revolves around Haumea in 18 days in an eccentric, non-Keplerian orbit, and as of 2008 is inclined 13° from Hiiaka. Over the timescale of the system, it should have been tidally damped into a more circular orbit. It appears that it has been disturbed by resonances with the more massive Hiiaka, due to converging orbits as it moved outward from Haumea because of tidal dissipation. The moons may have been caught in and then escaped from orbital resonance several times. They probably passed through the 3:1 resonance relatively recently, and currently are in or at least close to an 8:3 resonance.  Namaka's orbit is strongly perturbed, with a current precession of about -6.5° per year.

text: The Montshire Museum of Science is a hands-on, self-guided science museum located in Norwich, Vermont, in the United States.  It has roughly 150,000 visitors annually .  The museum, including the building and nature trails, is located on over 110 acres (445,000 m²) of land.  It has over 140 exhibits on anatomy, math, astronomy, mechanics, and natural history, among others.  Its live animal exhibits include a hive of honeybees that is connected to the outdoors and a colony of leafcutter ants.  Outside the museum building, there is a two-acre (8,000 m²) Science Park including a scaled model of the solar system (Pluto is located a two-mile (3 km) walk away), and exhibits on light, sound, and motion; among the sound exhibits there are "Whisper dishes" (parabolic dishes  apart) and a musical fence built by Paul Matisse, grandson of painter Henri Matisse.

text: The Lincoln Laboratory's Experimental Test Site (ETS) is an electro-optical test facility located on the grounds of the White Sands Missile Range in Socorro, New Mexico. The ETS is operated by the laboratory for the Air Force; its principal mission is the development, evaluation, and transfer of advanced electro-optical space surveillance technologies. The ETS has been a contributing sensor to the U.S. Air Force Space Command. A spin-off program for NASA, Lincoln Near-Earth Asteroid Research (LINEAR), uses the ground-based electro-optical deep-space surveillance telescopes at White Sands to discover comets and asteroids, in particular near-Earth objects. A large percentage share of all known minor planets in the Solar System have been discovered through this program. As of 2016, the Minor Planet Center credits LINEAR with the discovery of 147,183 numbered minor planets from 1997 to 2015. In terms of the total number of discoveries, LINEAR is the most successful asteroid survey program ever conducted.

text: In 1961, the International Astronomical Union defined a meteoroid as "a solid object moving in interplanetary space, of a size considerably smaller than an asteroid and considerably larger than an atom". In 1995, Beech and Steel, writing in the Quarterly Journal of the Royal Astronomical Society, proposed a new definition where a meteoroid would be between 100 µm and 10 meters across. In 2010, following the discovery of asteroids below 10 m in size, Rubin and Grossman revised the previous definition of meteoroid to objects between 10 µm and 1 m in diameter in order to maintain the distinction. According to Rubin and Grossman, the minimum size of an asteroid is given by what can be discovered from Earth-bound telescopes, so the distinction between meteoroid and asteroid is fuzzy. Some of the smallest asteroids discovered (based on absolute magnitude H) are  with H = 33.2 and  with H = 32.1 both with an estimated size of 1 meter. Objects smaller than meteoroids are classified as micrometeoroids and cosmic dust. The Minor Planet Center does not use the term "meteoroid".

text: Allende contains chondrules and CAIs that are estimated to be 4.567 billion years old, the oldest known matter (other carbonaceous chondrites also contain these).  This material is 30 million years older than the Earth and 287 million years older than the oldest rock known on Earth, Thus, the Allende meteorite  has revealed information about conditions prevailing during the early formation of the Solar System.  Carbonaceous chondrites, including Allende, are the most primitive meteorites, and contain the most primitive known matter.  They have undergone the least mixing and remelting since the early stages of Solar System formation. Because of this, their age is frequently taken as the "age of the Solar System."

They have undergone the least mixing and remelting since the early stages of Solar System formation. Because of this, their age is frequently taken as the "age of the Solar System."

text: In our Solar System, all of the planets and most of the other objects that orbit the Sun, with the exception of many comets, do so in the "prograde" direction, i.e. the same sense as the rotation of the Sun. Also the rotations of most planets are prograde, with the exceptions of Venus and Uranus, which have retrograde rotations. Most satellites of planets revolve around their planets in the prograde sense. (In the case of the satellites of Uranus, this means they revolve in the same sense as Uranus's rotation, which is retrograde relative to the Sun.) There are some satellites which orbit in the retrograde sense, but these are generally small and distant from their planets, except for Neptune's satellite Triton, which is large and close. It is thought that these retrograde satellites, including Triton, are bodies which have been captured into orbit around their planets, having been formed elsewhere.

text: The presence of Neptune has a profound effect on the Kuiper belt's structure due to orbital resonances. Over a timescale comparable to the age of the Solar System, Neptune's gravity destabilises the orbits of any objects that happen to lie in certain regions, and either sends them into the inner Solar System or out into the scattered disc or interstellar space. This causes the Kuiper belt to have pronounced gaps in its current layout, similar to the Kirkwood gaps in the asteroid belt. In the region between 40 and 42 AU, for instance, no objects can retain a stable orbit over such times, and any observed in that region must have migrated there relatively recently.

text: Pluto is the Olympian god of the Underworld, death, and the dead, and is the Monarch of Hades. Much of the character's story parallels that of traditional Greek Myth. To wit, after defeating their father Cronus, Pluto and his brothers Zeus and Neptune as well as his sisters Hera, Hestia and Demeter drew lots to divide Cronus' empire among them. Pluto gained control of the Underworld as the judge of the dead. However, in the Marvel Universe, Pluto is a scheming god that plans to overthrow Zeus, which no Greek Myth supports.

text: The first public transportation system in Erie was established on March 1, 1897 as the Erie City Passenger Railway Company. On October 8, 1888, the Erie Electric Motor Company took control of the Erie City Passenger Railway. The Conneaut and Erie Railway Traction Company was formed in 1903 and ran trolleys to east of the city. On December 24, 1906, the Buffalo and Lake Erie Traction Company took control of the Erie Electric Motor Company and completed its  line to Buffalo, New York in 1909. When the Conneaut and Erie was abandoned on September 16, 1922, the West Ridge Transportation Company was started the next year to run buses along the abandoned trolley route. The Buffalo and Lake Erie was reorganized into the Buffalo and Erie Railway Company on September 5, 1924 and the streetcar system in Erie was split from the Buffalo and Erie to form the Erie Railways Company. Unable to expanded to invest in an expansion of the streetcar system, four Yellow Coach "Z"'s were acquired and were operated by the Erie Coach Company, a newly formed subsidiary of the Erie Railways Company in 1925. The last of its trolleys ran between Erie and New York on December 1, 1932. The streetcars were put out of service in 1935. The city and county took over the Erie Coach Company and formed the Erie Metropolitan Transit Authority on September 20, 1966.

text: Initial results were surprising as the material excavated by the impact contained more dust and less ice than had been expected. The only models of cometary structure astronomers could positively rule out were the very porous ones which had comets as loose aggregates of material. In addition, the material was finer than expected; scientists compared it to talcum powder rather than sand. Other materials found while studying the impact included clays, carbonates, sodium, and crystalline silicates which were found by studying the spectroscopy of the impact. Clays and carbonates usually require liquid water to form and sodium is rare in space. Observations also revealed that the comet was about 75% empty space, and one astronomer compared the outer layers of the comet to the same makeup of a snow bank. Astronomers have expressed interest in more missions to different comets to determine if they share similar compositions or if there are different materials found deeper within comets that were produced at the time of the Solar System's formation.

text: The name of Eris's moon Dysnomia was suggested by its discoverer Michael E. Brown, who also suggested the name of the dwarf planet. The name has two meanings: in mythology Dysnomia (lawlessness) is the daughter of Eris (chaos). However, the name is also an intentional reference to the actor Lucy Lawless who plays the character Xena. The background for this is that during the long period when Eris had no formal name, the name 'Xena' – originally Brown's nickname for his discovery – spread and became popular. When the name 'Eris' was chosen, Brown suggested Dysnomia (which until then had been referred to as Gabrielle) as a reference to this. Hence, Dysnomia is the only moon which could be said to be named after an actor. The names Eris and Dysnomia were accepted by the IAU on 14 September 2006.

text: Pluto has five known natural satellites: Charon, first identified in 1978 by astronomer James Christy; Nix and Hydra, both discovered in 2005; Kerberos, discovered in 2011; and Styx, discovered in 2012. The satellites' orbits are circular (eccentricity < 0.006) and coplanar with Pluto's equator (inclination < 1°), and therefore tilted approximately 120° relative to Pluto's orbit. The Plutonian system is highly compact: the five known satellites orbit within the inner 3% of the region where prograde orbits would be stable. Closest to Pluto is Charon, which is large enough to be in hydrostatic equilibrium and to cause the barycenter of the Pluto–Charon system to be outside Pluto. Beyond Charon there are four much smaller circumbinary moons, Styx, Nix, Kerberos, and Hydra.

text: Subsequent explorations of the Solar System by space probes made it possible to obtain precise measurements of the relative positions of the inner planets and other objects by means of radar and telemetry. As with all radar measurements, these rely on measuring the time taken for photons to be reflected from an object. Because all photons move at the speed of light in vacuum, a fundamental constant of the universe, the distance of an object from the probe is basically the product of the speed of light and the measured time. However, for precision the calculations require adjustment for things such as the motions of the probe and object while the photons are transiting. In addition, the measurement of the time itself must be translated to a standard scale that accounts for relativistic time dilation. Comparison of the ephemeris positions with time measurements expressed in the TDB scale leads to a value for the speed of light in astronomical units per day (of ). By 2009, the IAU had updated its standard measures to reflect improvements, and calculated the speed of light at  (TDB).

text: Makemake is a classical Kuiper belt object, which means its orbit lies far enough from Neptune to remain stable over the age of the Solar System. Unlike plutinos, which can cross Neptune's orbit due to their 2:3 resonance with the planet, the classical objects have perihelia further from the Sun, free from Neptune's perturbation. Such objects have relatively low eccentricities (e below 0.2) and orbit the Sun in much the same way the planets do. Makemake, however, is a member of the "dynamically hot" class of classical KBOs, meaning that it has a high inclination compared to others in its population. Makemake is, probably coincidentally, near the 11:6 resonance with Neptune.

text: The overall structure of the charted regions of the Solar System consists of the Sun, four relatively small inner planets surrounded by a belt of mostly rocky asteroids, and four giant planets surrounded by the Kuiper belt of mostly icy objects. Astronomers sometimes informally divide this structure into separate regions. The inner Solar System includes the four terrestrial planets and the asteroid belt. The outer Solar System is beyond the asteroids, including the four giant planets. Since the discovery of the Kuiper belt, the outermost parts of the Solar System are considered a distinct region consisting of the objects beyond Neptune.

text: The collection The Solar System Beyond Neptune (2008) defines objects with a semi-major axis between those of Jupiter and Neptune and a Jupiter – Tisserand's parameter above 3.05 – as centaurs, classifying the objects with a Jupiter Tisserand's parameter below this and, to exclude Kuiper belt objects, an arbitrary perihelion cut-off half-way to Saturn (q < 7.35) as Jupiter-family comets and classifying those objects on unstable orbits with a semi-major axis larger than Neptune's as members of the scattered disc. Other astronomers prefer to define centaurs as objects that are non-resonant with a perihelion inside the orbit of Neptune that can be shown to likely cross the Hill sphere of a gas giant within the next 10 million years, so that centaurs can be thought of as objects scattered inwards and that interact more strongly and scatter more quickly than typical scattered-disc objects.

text: It is suspected that Pluto's satellite system was created by a massive collision, similar to the "big whack" thought to have created the Moon. In both cases, the high angular momenta of the moons can only be explained by such a scenario. The nearly circular orbits of the smaller moons suggests that they were also formed in this collision, rather than being captured Kuiper Belt objects. This and their near orbital resonances with Charon (see below) suggest that they formed closer to Pluto than they are at present and migrated outward as Charon reached its current orbit. Their grey color is different from that of Pluto, one of the reddest bodies in the Solar System. This is thought to be due to a loss of volatiles during the impact or subsequent coalescence, leaving the surfaces of the moons dominated by water ice. However, such an impact should have created additional debris (more moons), yet no moons or rings were discovered by New Horizons, ruling out any more moons of significant size orbiting Pluto.

text: The oldest inclusions found in meteorites, thought to trace the first solid material to form in the pre-solar nebula, are 4568.2 million years old, which is one definition of the age of the Solar System. Studies of ancient meteorites reveal traces of stable daughter nuclei of short-lived isotopes, such as iron-60, that only form in exploding, short-lived stars. This indicates that one or more supernovae occurred near the Sun while it was forming. A shock wave from a supernova may have triggered the formation of the Sun by creating relatively dense regions within the cloud, causing these regions to collapse. Because only massive, short-lived stars produce supernovae, the Sun must have formed in a large star-forming region that produced massive stars, possibly similar to the Orion Nebula. Studies of the structure of the Kuiper belt and of anomalous materials within it suggest that the Sun formed within a cluster of between 1,000 and 10,000 stars with a diameter of between 6.5 and 19.5 light years and a collective mass of . This cluster began to break apart between 135 million and 535 million years after formation. Several simulations of our young Sun interacting with close-passing stars over the first 100 million years of its life produce anomalous orbits observed in the outer Solar System, such as detached objects.

text: Leonid Ksanfomaliti of the Space Research Institute of Russia's Academy of Sciences (a contributor to the Venera mission) and Stan Karaszewski of Karas, in Solar System Research, suggests signs of life in the Venera images. According to Ksanfomaliti, certain objects  resembled a "disk", a "black flap" and a "scorpion" which "emerge, fluctuate and disappear", referring to their changing location on different photographs and traces on the ground. The article was titled "Venus as a natural laboratory for search of life in high temperature conditions: Events on the planet on March 1, 1982", L. V. Ksanfomality, Solar System Research, February 2012, Volume 46, Issue 1, pp 41–5. Engineers familiar with the probe have identified the moving "disk" as actually being the two lens caps ejected from the lander. Rather than a single object that had moved between two different places, they are simply two inanimate similar-looking objects in different places. The other "objects" are ascribed to image processing artifacts and do not appear in the original photography.

text: Unlike most other chondrites, the minerals in enstatite chondrites contain almost no iron oxide; they are the most oxygen-poor silicate rocks known. They are also the driest objects in the solar system, consisting of only 0.01% water. Metallic Fe-Ni (iron-nickel) and Fe-bearing sulfide minerals contain nearly all of the iron in this type of meteorite. Enstatite chondrites contain a variety of unusual minerals that can only form in extremely reducing conditions, including oldhamite (CaS), niningerite (MgS), perryite (Fe-Ni silicide), and alkali sulfides (e.g., djerfisherite and caswellsilverite). All enstatite chondrites are dominantly composed of enstatite-rich chondrules plus abundant grains of metal and sulfide minerals. Dusty matrix material is uncommon and refractory inclusions are very rare. Chemically, enstatite chondrites are very low in refractory lithophile elements. Their oxygen isotopic compositions are intermediate between ordinary and carbonaceous chondrites, and are similar to rocks found on the Earth and Moon. Their lack of oxygen content may mean that they were originally formed near the center of the solar nebula that created the solar system, possibly within the orbit of Mercury. Most enstatite chondrites have experienced thermal metamorphism on the parent asteroids. They are divided into two groups:

text: In addition, since 2002 there is also an International Max Planck Research School.Subjects of research at the Institute are the various objects within the solar system.

text: The definition would have considered a pair of objects to be a double planet system if each component independently satisfied the planetary criteria and the common center of gravity of the system (known as the barycenter) was located outside of both bodies. Pluto and Charon would have been the only known double planet in the Solar System. Other planetary satellites (like Earth and its moon) might be in hydrostatic equilibrium, but would still not have been defined as a component of a double planet, since the barycenter of the system lies within the more massive celestial body (the Earth).

text: Although Interamnia is the largest asteroid after the "big four", it is a very little-studied body. It is easily the largest of the F-type asteroids, but there exist very few details of its internal composition or shape, and no light curve analysis has yet been done to determine the ecliptic coordinates of Interamnia's poles (and hence its axial tilt). Its apparently high bulk density (though subject to much error) suggests an extremely solid body entirely without internal porosity or traces of water. This also strongly suggests that Interamnia is large enough to have fully withstood all the collisions that have occurred in the asteroid belt since the Solar System was formed.

text: Nineteen moons are known to be massive enough to have relaxed into a rounded shape under their own gravity, and seven of them are more massive than either Eris or Pluto. They are not physically distinct from the dwarf planets, but are not dwarf planets because they do not directly orbit the Sun. The seven that are more massive than Eris are the Moon, the four Galilean moons of Jupiter (Io, Europa, Ganymede, and Callisto), one moon of Saturn (Titan), and one moon of Neptune (Triton). The others are six moons of Saturn (Mimas, Enceladus, Tethys, Dione, Rhea, and Iapetus), five moons of Uranus (Miranda, Ariel, Umbriel, Titania, and Oberon), and one moon of Pluto (Charon). There are additional possibilities among TNOs, including Dysnomia orbiting Eris. Alan Stern calls these moons "satellite planets", one of three categories of planet together with dwarf planets and classical planets. The term planemo ("planetary-mass object") covers all three.

text: Crater counts give an important estimate for the age of the surface of a planet. Over time, bodies in the Solar System are randomly impacted, so the more craters a surface has, the older it is. Compared to Mercury, the Moon and other such bodies, Venus has very few craters. In part, this is because Venus's dense atmosphere burns up smaller meteorites before they hit the surface. The Venera and Magellan data agree: there are very few impact craters with a diameter less than , and data from Magellan show an absence of any craters less than  in diameter. However, there are also fewer of the large craters, and those appear relatively young; they are rarely filled with lava, showing that they happened after volcanic activity in the area, and radar shows that they are rough and have not had time to be eroded down.

text: The expression "asteroid belt" came into use in the very early 1850s, although it is hard to pinpoint who coined the term. The first English use seems to be in the 1850 translation (by E. C. Otté) of Alexander von Humboldt's Cosmos: "[...] and the regular appearance, about the 13th of November and the 11th of August, of shooting stars, which probably form part of a belt of asteroids intersecting the Earth's orbit and moving with planetary velocity". Other early appearances occur in Robert James Mann's A Guide to the Knowledge of the Heavens, "The orbits of the asteroids are placed in a wide belt of space, extending between the extremes of [...]". The American astronomer Benjamin Peirce seems to have adopted that terminology and to have been one of its promoters. One hundred asteroids had been located by mid-1868, and in 1891 the introduction of astrophotography by Max Wolf accelerated the rate of discovery still further. A total of 1,000 asteroids had been found by 1921, 10,000 by 1981, and 100,000 by 2000. Modern asteroid survey systems now use automated means to locate new minor planets in ever-increasing quantities.

A small, largely symbolic quantity of "sky-iron" might be added, or it might be included as a significant part of the alloy-recipe.

text: There is, however, another comet population, known as short-period or periodic comets, consisting of those comets that, like Halley's Comet, have orbital periods of less than 200 years. By the 1970s, the rate at which short-period comets were being discovered was becoming increasingly inconsistent with their having emerged solely from the Oort cloud. For an Oort cloud object to become a short-period comet, it would first have to be captured by the giant planets. In 1980, in the Monthly Notices of the Royal Astronomical Society, Uruguayan astronomer Julio Fernández stated that for every short-period comet to be sent into the inner Solar System from the Oort cloud, 600 would have to be ejected into interstellar space. He speculated that a comet belt from between 35 and 50 AU would be required to account for the observed number of comets. Following up on Fernández's work, in 1988 the Canadian team of Martin Duncan, Tom Quinn and Scott Tremaine ran a number of computer simulations to determine if all observed comets could have arrived from the Oort cloud. They found that the Oort cloud could not account for all short-period comets, particularly as short-period comets are clustered near the plane of the Solar System, whereas Oort-cloud comets tend to arrive from any point in the sky. With a "belt", as Fernández described it, added to the formulations, the simulations matched observations. Reportedly because the words "Kuiper" and "comet belt" appeared in the opening sentence of Fernández's paper, Tremaine named this hypothetical region the "Kuiper belt".

text: Like other members of the Kuiper belt, Pluto is thought to be a residual planetesimal; a component of the original protoplanetary disc around the Sun that failed to fully coalesce into a full-fledged planet. Most astronomers agree that Pluto owes its current position to a sudden migration undergone by Neptune early in the Solar System's formation. As Neptune migrated outward, it approached the objects in the proto-Kuiper belt, setting one in orbit around itself (Triton), locking others into resonances, and knocking others into chaotic orbits. The objects in the scattered disc, a dynamically unstable region overlapping the Kuiper belt, are thought to have been placed in their current positions by interactions with Neptune's migrating resonances. A computer model created in 2004 by Alessandro Morbidelli of the Observatoire de la Côte d'Azur in Nice suggested that the migration of Neptune into the Kuiper belt may have been triggered by the formation of a 1:2 resonance between Jupiter and Saturn, which created a gravitational push that propelled both Uranus and Neptune into higher orbits and caused them to switch places, ultimately doubling Neptune's distance from the Sun. The resultant expulsion of objects from the proto-Kuiper belt could also explain the Late Heavy Bombardment 600 million years after the Solar System's formation and the origin of the Jupiter trojans. It is possible that Pluto had a near-circular orbit about 33 AU from the Sun before Neptune's migration perturbed it into a resonant capture. The Nice model requires that there were about a thousand Pluto-sized bodies in the original planetesimal disk, which included Triton and Eris.

text: In the outer Solar System, comets remain frozen and inactive and are extremely difficult or impossible to detect from Earth due to their small size. Statistical detections of inactive comet nuclei in the Kuiper belt have been reported from observations by the Hubble Space Telescope but these detections have been questioned. As a comet approaches the inner Solar System, solar radiation causes the volatile materials within the comet to vaporize and stream out of the nucleus, carrying dust away with them.

text: An example of an extinct radionuclide is xenon-129, a stable isotope of xenon which appears as a relative excess against other xenon isotopes. It is found in meteorites that condensed from the primordial solar system dust cloud and trapped promordial iodine-129 (half life 15.7 million years) some time in a relative short period (probably less than 20 million years) between the iodine-129's creation in a supernova, and the formation of the solar system by condensation of this dust. The trapped iodine-129 now appears as a relative excess of xenon-129. Iodine-129 was the first extinct radionuclide to be inferred, in 1960. Others are aluminium-26 (also inferred from extra magnesium-26 found in meteorites), and iron-60.

text: Wallis and Wickramasinghe argued in 2004 that the transport of individual bacteria or clumps of bacteria, is overwhelmingly more important than lithopanspermia in terms of numbers of microbes transferred, even accounting for the death rate of unprotected bacteria in transit. Then it was found that isolated spores of B. subtilis were killed by several orders of magnitude if exposed to the full space environment for a mere few seconds. These results clearly negate the original panspermia hypothesis, which requires single spores as space travelers accelerated by the radiation pressure of the Sun, requiring many years to travel between the planets. However, if shielded against solar UV, spores of Bacillus subtilis were capable of surviving in space for up to 6 years, especially if embedded in clay or meteorite powder (artificial meteorites). The data support the likelihood of interplanetary transfer of microorganisms within meteorites, the so-called lithopanspermia hypothesis.<ref name='Gerda Horneck' />

text: The term "minor planet" would have been abandoned, replaced by the categories "small Solar System body" (SSSB) and a new classification of "pluton". The former would have described those objects underneath the "spherical" threshold. The latter would have been applied to those planets with highly inclined orbits, large eccentricities and an orbital period of more than 200 earth years (that is, those orbiting beyond Neptune). Pluto would have been the prototype for this class. The term "dwarf planet" would have been available to describe all planets smaller than the eight "classical planets" in orbit around the Sun, though would not have been an official IAU classification. The IAU did not make recommendations in the draft resolution on what separated a planet from a brown dwarf. A vote on the proposal was scheduled for August 24, 2006.

text: There are types of planets that do not exist in the Solar System: super-Earths and mini-Neptunes, which could be rocky like Earth or a mixture of volatiles and gas like Neptune—a radius of 1.75 times that of Earth is a possible dividing line between the two types of planet. There are hot Jupiters that orbit very close to their star and may evaporate to become chthonian planets, which are the leftover cores. Another possible type of planet is carbon planets, which form in systems with a higher proportion of carbon than in the Solar System.

text: The center of mass (barycenter) of the Pluto–Charon system lies outside either body. Because neither object truly orbits the other, and Charon has 12.2% the mass of Pluto, it has been argued that Charon should be considered to be part of a binary system with Pluto. The International Astronomical Union (IAU) states that Charon is considered to be just a satellite of Pluto, but the idea that Charon might be classified a dwarf planet in its own right may be considered at a later date.

text: Beyond the orbit of Neptune lies the area of the "trans-Neptunian region", with the doughnut-shaped Kuiper belt, home of Pluto and several other dwarf planets, and an overlapping disc of scattered objects, which is tilted toward the plane of the Solar System and reaches much further out than the Kuiper belt. The entire region is still largely unexplored. It appears to consist overwhelmingly of many thousands of small worlds—the largest having a diameter only a fifth that of Earth and a mass far smaller than that of the Moon—composed mainly of rock and ice. This region is sometimes described as the "third zone of the Solar System", enclosing the inner and the outer Solar System.

Due to their greater distance from the Sun, the solid objects in the outer Solar System contain a higher proportion of volatiles, such as water, ammonia, and methane than those of the inner Solar System because the lower temperatures allow these compounds to remain solid.

text: Given that Toutatis makes many close approaches to Earth, such as in 1992, 1996, 2000, 2004, 2008, and 2012, it is listed as a potentially hazardous object. With an uncertainty parameter of 0, the orbit of Toutatis is very well determined for the next few hundred years. The probability of the orbit intersecting Earth is essentially zero for at least the next six centuries. The likelihood of collision in the distant future is considered to be very small. As a planet-crossing asteroid, Toutatis is likely to be ejected from the inner Solar System within a time scale of a few million years or less, giving it a limited number of opportunities to hit Earth. In 2004 a chain e-mail falsely claimed that Toutatis had a 63 percent chance of impacting Earth that year. In fact, Toutatis passed by at 1.5 million kilometres, or about four Earth–Moon distances, as predicted.

text: Unlike a natural ecosystem which is regulated by the interaction of many different species; an artificially closed ecosystem has a reduced number of steps and it is sized and controlled to reach the desired objectives. It is akin to  industrial processes, transforming raw materials into useful substances. However, one key difference is the targeted objective to recycle near 100% of wastes (limiting feed stock), essentially operating MELiSSA in a closed loop. Achieving near 100% for the major elements is of course theoretical. When compared to natural ecosystems, even Earth isn’t a truly closed system: every year thousands of tons of meteoric matter come from space. Further, an artificial ecosystem is inherently dynamic, MELiSSA has to respond very quickly to changes in human behaviour. This requires a dynamic control system which is developed for each step of the process and the system as a whole.

text: "Our newly discovered object is the coldest most distant place known in the Solar System", said Mike Brown on his website, "so we feel it is appropriate to name it in honor of Sedna, the Inuit goddess of the sea, who is thought to live at the bottom of the frigid Arctic Ocean." Brown also suggested to the International Astronomical Union's (IAU) Minor Planet Center that any future objects discovered in Sedna's orbital region should also be named after entities in arctic mythologies. The team made the name "Sedna" public before the object had been officially numbered. Brian Marsden, the head of the Minor Planet Center, said that such an action was a violation of protocol, and that some members of the IAU might vote against it. However, no objection was raised to the name, and no competing names were suggested. The IAU's Committee on Small Body Nomenclature formally accepted the name in September 2004, and also considered that, in similar cases of extraordinary interest, it might in the future allow names to be announced before they were officially numbered.

text: Although the sizes of comets are difficult to determine without close observation, Comet Elenin is likely to be less than 10 km in diameter. Elenin himself estimates that the comet nucleus is roughly 3–4 km in diameter. This would make it millions of times smaller than the supposed Nibiru. Comet hysteria is not uncommon. Attempts have been made to correlate Elenin's alignments with the 2011 Japan earthquake, the 2010 Canterbury earthquake, and 2010 Chile earthquake; however, even discounting Elenin's tiny size, earthquakes are driven by forces within the earth, and cannot be triggered by the passage of nearby objects. In 2011, Leonid Elenin ran a simulation on his blog in which he increased the mass of the comet to that of a brown dwarf (0.05 solar masses). He demonstrated that its gravity would have caused noticeable changes in the orbit of Saturn years before its arrival in the inner Solar System.

text: The following is a list of parabolic and hyperbolic comets in the Solar System. Many of these comets may come from the Oort cloud, or perhaps even have interstellar origin. Due to the Oort Cloud not being gravitationally attracted enough to the Sun to form into a fairly thin disk, like the inner Solar System, comets originating from it can come from roughly any orientation, and many even orbit retrograde. By definition, a hyperbolic orbit means that the comet will only travel through the Solar System once, with the Sun acting as a gravitational slingshot, sending the comet hurtling out of the Solar System entirely unless its eccentricity is otherwise changed. Comets orbiting in this way still originate from the Solar System, however. Typically comets in the Oort Cloud are thought to have roughly circular orbits around the Sun, but their orbital velocity is so slow that they are easily perturbed by passing stars and the galactic tide.

Because the Sun contains 99.86% of the mass of the Solar System, they are considered to have the same composition as the solar nebula with the exception of volatile loss and are therefore representative of the material from which the terrestrial planets, including the Earth, were formed.

text: Haumea displays large fluctuations in brightness over a period of 3.9 hours, which can only be explained by a rotational period of this length. This is faster than any other known equilibrium body in the Solar System, and indeed faster than any other known body larger than 100 km in diameter. This rapid rotation is thought to have been caused by the impact that created its satellites and collisional family.

text: Following guidelines established by the IAU that classical Kuiper belt objects be given names of mythological beings associated with creation, in September 2006 the Caltech team submitted formal names from Hawaiian mythology to the IAU for both (136108) 2003 EL and its moons, in order "to pay homage to the place where the satellites were discovered". The names were proposed by David Rabinowitz of the Caltech team. Haumea is the matron goddess of the island of Hawaii, where the Mauna Kea Observatory is located. In addition, she is identified with Papa, the goddess of the earth and wife of Wākea (space), which is appropriate because Haumea is thought to be composed almost entirely of solid rock, without the thick ice mantle over a small rocky core typical of other known Kuiper belt objects. Lastly, Haumea is the goddess of fertility and childbirth, with many children who sprang from different parts of her body; this corresponds to the swarm of icy bodies thought to have broken off the dwarf planet during an ancient collision. The two known moons, also believed to have formed in this manner, are thus named after two of Haumea's daughters, Hiʻiaka and Nāmaka.

text: Shortly after Voyager 2s flyby of Neptune and its findings at Triton in August 1989, scientists sought interest in a mission to Pluto and further studies for the existence of a Kuiper belt and Kuiper belt objects, potentially similar to Triton. All four outer planets were explored by Voyager 2, launched in 1977, with close approaches to Jupiter, Saturn, Uranus, and Neptune. After a Neptune encounter, the alignment of Pluto made it impossible for Voyager 2 to continue there, leaving it on a trajectory out of the Solar System.

text: The Solar System began forming about 4.6 billion years ago, or about 9 billion years after the Big Bang. A fragment of a molecular cloud made mostly of hydrogen and traces of other elements began to collapse, forming a large sphere in the center which would become the Sun, as well as a surrounding disk. The surrounding accretion disk would coalesce into a multitude of smaller objects that would become planets, asteroids, and comets.

text: For example, in paper industry when designing a paper mill, one can seek to decrease the amount of capital invested in a paper mill and enhance the quality of paper simultaneously. If the design of a paper mill is defined by large storage volumes and paper quality is defined by quality parameters, then the problem of optimal design of a paper mill can include objectives such as: i) minimization of expected variation of those quality parameter from their nominal values, ii) minimization of expected time of breaks and iii) minimization of investment cost of storage volumes. Here, maximum volume of towers are design variables. This example of optimal design of a paper mill is a simplification of the model used in.  Multi-objective design optimization have also been implemented in engineering systems - e.g. design of nano-CMOS semiconductors, design of solar-powered irrigation systems, optimization of sand mould systems, engine design, optimal sensor deployment and optimal controller design.

text: In November 2010, Eris was the subject of one of the most distant stellar occultations yet from Earth. Preliminary data from this event cast doubt on previous size estimates. The teams announced their final results from the occultation in October 2011, with an estimated diameter of . The mass of Eris can be calculated with much greater precision. Based on the currently accepted value for Dysnomia's period—15.774 days— Eris is 27 percent more massive than Pluto. If the 2011 occultation results are used, then Eris has a density of , substantially denser than Pluto, and thus must be composed largely of rocky materials.

text: Pluto's surface is composed of more than 98 percent nitrogen ice, with traces of methane and carbon monoxide. Nitrogen and carbon monoxide are most abundant on the anti-Charon face of Pluto (around 180° longitude, where Tombaugh Regio's western lobe, Sputnik Planitia, is located), whereas methane is most abundant near 300° east. Pluto's surface is quite varied, with large differences in both brightness and color. Pluto is one of the most contrastive bodies in the Solar System, with as much contrast as Saturn's moon Iapetus. The color varies between charcoal black, dark orange and white. Pluto's color is more similar to that of Io with slightly more orange, significantly less red than Mars. Notable geographical features include Tombaugh Regio, or the "Heart" (a large bright area on the side opposite Charon), Cthulhu Regio, or the "Whale" (a large dark area on the trailing hemisphere), and the "Brass Knuckles" (a series of equatorial dark areas on the leading hemisphere). Sputnik Planitia, the western lobe of the "Heart", is a 1000 km-wide basin of frozen nitrogen and carbon monoxide ices, divided into polygonal cells which are interpreted as convection cells that carry floating blocks of water ice crust and sublimation pits towards their margins; there are obvious signs of glacial flows both into and out of the basin. It has no craters that were visible to New Horizons, indicating that its surface is less than 10 million years old. The New Horizons science team summarized initial findings as "Pluto displays a surprisingly wide variety of geological landforms, including those resulting from glaciological and surface–atmosphere interactions as well as impact, tectonic, possible cryovolcanic, and mass-wasting processes."

text: The concept of hydrostatic equilibrium has also become important in determining whether an astronomical object is a planet, dwarf planet, or small Solar System body. According to the definition of planet adopted by the International Astronomical Union in 2006, one defining characteristic of planets and dwarf planets is that they are objects that have sufficient gravity to overcome their own rigidity and assume hydrostatic equilibrium. Such a body will normally have the differentiated interior and geology of a world (a planemo), though near-hydrostatic bodies such as the proto-planet 4 Vesta may also be differentiated. Sometimes the equilibrium shape is an oblate spheroid, as is the case with Earth. However, in the cases of moons in synchronous orbit, nearly unidirectional tidal forces create a scalene ellipsoid. Also, the dwarf planet  is scalene due to its rapid rotation.

text: The high population of the asteroid belt makes for a very active environment, where collisions between asteroids occur frequently (on astronomical time scales). Collisions between main-belt bodies with a mean radius of 10 km are expected to occur about once every 10 million years. A collision may fragment an asteroid into numerous smaller pieces (leading to the formation of a new asteroid family). Conversely, collisions that occur at low relative speeds may also join two asteroids. After more than 4 billion years of such processes, the members of the asteroid belt now bear little resemblance to the original population.

text: The comet is thought to be a member of a relatively new class of objects called "centaurs", of which at least 80 are known. These are small icy bodies with orbits between those of Jupiter and Neptune. Astronomers believe that centaurs are recent escapees from the Kuiper belt, a zone of small bodies orbiting in a cloud at the distant reaches of the Solar System. Frequent perturbations by Jupiter will likely accumulate and cause the comet to migrate either inward or outward by the year 4000.

text: A meteor, known colloquially as a "shooting star" or "falling star", is the visible passage of a glowing meteoroid, micrometeoroid, comet or asteroid through Earth's atmosphere, after being heated to incandescence by collisions with air molecules in the upper atmosphere, creating a streak of light via its rapid motion and sometimes also by shedding glowing material in its wake. Meteors typically occur in the mesosphere at altitudes from . The root word meteor comes from the Greek meteōros, meaning "high in the air".

text: In 2008, the IAU modified its naming procedures such that objects considered most likely to be dwarf planets receive differing treatment than others. Objects that have an absolute magnitude (H) less than +1 (and hence a minimum diameter of  if the albedo is below 100%) are overseen by two naming committees, one for minor planets and one for planets. Once named, the objects are declared to be dwarf planets. Makemake and Haumea are the only objects to have proceeded through the naming process as presumed dwarf planets; currently there are no other bodies that meet this criterion. All other bodies are named by the minor-planet naming committee alone, and the IAU has not stated how or if they will be accepted as dwarf planets.

text: Several major variants of the Meteor incorporated technological advances during the 1940s and 1950s. Thousands of Meteors were built to fly with the RAF and other air forces and remained in use for several decades. The Meteor saw limited action in the Second World War. Meteors of the Royal Australian Air Force (RAAF) fought in the Korean War. Several other operators such as Argentina, Egypt and Israel flew Meteors in later regional conflicts. Specialised variants of the Meteor were developed for use in photographic aerial reconnaissance and as night fighters.

text: At the time of planning, it was estimated that WISE would detect about 300,000 main-belt asteroids, of which approximately 100,000 will be new, and some 700 near-Earth objects (NEO) including about 300 undiscovered. That translates to about 1000 new main-belt asteroids per day, and 1–3 NEOs per day. The peak of magnitude distribution for NEOs will be about 21–22 V. WISE would detect each typical Solar System object 10–12 times over about 36 hours in intervals of 3 hours.

text: The first spacecraft to traverse the asteroid belt was Pioneer 10, which entered the region on 16 July 1972. At the time there was some concern that the debris in the belt would pose a hazard to the spacecraft, but it has since been safely traversed by 12 spacecraft without incident. Pioneer 11, Voyagers 1 and 2 and Ulysses passed through the belt without imaging any asteroids. Galileo imaged 951 Gaspra in 1991 and 243 Ida in 1993, NEAR imaged 253 Mathilde in 1997, Cassini imaged 2685 Masursky in 2000, Stardust imaged 5535 Annefrank in 2002, New Horizons imaged 132524 APL in 2006, Rosetta imaged 2867 Šteins in September 2008 and 21 Lutetia in July 2010, and Dawn orbited Vesta between July 2011 and September 2012 and has orbited Ceres since March 2015. On its way to Jupiter, Juno traversed the asteroid belt without collecting science data. Due to the low density of materials within the belt, the odds of a probe running into an asteroid are now estimated at less than one in a billion.

text: Saturn's rings could give a further hint to identifying the Solar System. Rings around the planets Jupiter, Uranus and Neptune were unknown when the plaque was designed; however, unlike Saturn the ring systems on these planets are not as easily visible and apparent as Saturn's. Pluto was considered to be a planet when the plaque was designed; in 2006 the IAU reclassified Pluto as a dwarf planet and then in 2008 as a plutoid. Other large bodies classed as dwarf planets, such as Eris, are not depicted, as they were unknown at the time the plaque was made.

text: Closer investigation using a simpler model with one planet and a planetesimal disk indicated that the energy transfer was due to a coupling between the eccentricity of the planetesimals in the outer belt and the semi-major axis of the planet. As a result of this coupling an increase in the average eccentricity of the planetesimal belt driven via the gravitational stirring by Pluto-sized objects yields a decrease in the semi-major axis of the planet. The coupling was found to be proportional to the eccentricity of the planet and in a multiple planet system would have its greatest effect on the most eccentric planet.

text: A number of solar system objects that are mostly to completely invisible to the human eye are reasonably detectable with medium-size binoculars, including larger craters on the Moon; the dim outer planets Uranus and Neptune; the inner "minor planets" Ceres, Vesta and Pallas; Saturn's largest moon Titan; and the Galilean moons of Jupiter. Although visible unaided in pollution-free skies, Uranus and Vesta require binoculars for easy detection. 10×50 binoculars are limited to an apparent magnitude of +9.5 to +11 depending on sky conditions and observer experience. Asteroids like Interamnia, Davida, Europa and, unless under exceptional conditions Hygiea, are too faint to be seen with commonly sold binoculars. Likewise too faint to be seen with most binoculars are the planetary moons except the Galileans and Titan, and the dwarf planets Pluto and Eris. Other difficult binocular targets include the phases of Venus and the rings of Saturn. Only binoculars with very high magnification, 20x or higher, are capable of discerning Saturn's rings to a recognizable extent.  High-power binoculars can sometimes show one or two cloud belts on the disk of Jupiter if optics and observing conditions are sufficiently good.

text: The orbits of the vast majority of small Solar System bodies are located in two distinct areas, namely the asteroid belt and the Kuiper belt. These two belts possess some internal structure related to perturbations by the major planets (particularly Jupiter and Neptune, respectively), and have fairly loosely defined boundaries. Other areas of the Solar System also encompass small bodies in smaller concentrations. These include the near-Earth asteroids, centaurs, comets, and scattered disc objects.

text: When natural satellites are first discovered, they are given provisional designations such as "S/2010 J 2" (the 2nd new satellite of Jupiter discovered in 2010) or "S/2003 S 1" (the 1st new satellite of Saturn discovered in 2003). The initial "S/" stands for "satellite", and distinguishes from such prefixes as "D/", "C/", and "P/", used for comets. The designation "R/" is used for planetary rings. These designations are sometimes written like "S/2003 S1", dropping the second space. The letter following the category and year identifies the planet (Jupiter, Saturn, Uranus, Neptune; although no occurrence of the other planets is expected, Mars and Mercury are disambiguated through the use of Hermes for the latter). Pluto was designated by P prior to its recategorization as a dwarf planet. When the object is found around a minor planet, the identifier used is the latter's number in parentheses. Thus, Dactyl, the moon of 243 Ida, was at first designated "S/1993 (243) 1". Once confirmed and named, it became (243) Ida I Dactyl. Similarly, the fourth satellite of Pluto, Kerberos, discovered after Pluto was categorized as a dwarf planet and assigned a minor planet number, was designated S/2011 (134340) 1 rather than S/2011 P 1, though the New Horizons team, who disagreed with the dwarf planet classification, used the latter.

text: A close encounter with Earth is predicted for the comet's return to the inner Solar System in the year 4479, around Sept. 15; the closest approach is estimated to be 0.03–0.05 AU, with a probability of impact of 1, or 0.0001%. Subsequent to 4479, the orbital evolution of the comet is more difficult to predict; the probability of Earth impact per orbit is estimated as 2 (0.000002%). It is the largest Solar System object that makes repeated close approaches to Earth with a relative velocity of 60 km/s. An Earth impact would have an estimated energy of ≈27 times that of the Cretaceous–Paleogene impactor. Comet Swift–Tuttle has been described as "the single most dangerous object known to humanity".

text: Michael E. Brown (born June 5, 1965) is an American astronomer, who has been professor of planetary astronomy at the California Institute of Technology (Caltech) since 2003. His team has discovered many trans-Neptunian objects (TNOs), notably the dwarf planet Eris, the only known TNO more massive than Pluto.

text: When a meteoroid, comet, or asteroid enters Earth's atmosphere at a speed typically in excess of , aerodynamic heating of that object produces a streak of light, both from the glowing object and the trail of glowing particles that it leaves in its wake. This phenomenon is called a meteor or "shooting star". A series of many meteors appearing seconds or minutes apart and appearing to originate from the same fixed point in the sky is called a meteor shower. If that object withstands ablation from its passage through the atmosphere as a meteor and impacts with the ground, it is then called a meteorite.

text: If interstellar comets exist, they must occasionally pass through the inner Solar System. They would approach the Solar System with random velocities, mostly from the region of the constellation Hercules because the Solar System is moving in that direction. The fact that no comet with a speed greater than the Sun's escape velocity has yet been seen places upper limits to their density in interstellar space. A paper by Torbett indicates that the density is no more than 10 (10 trillion) comets per cubic parsec. Other analyses, of data from LINEAR, set the upper limit at 4.5/AU, or 10 (1 trillion) comets per cubic parsec.

text: Another way in which asteroids could be considered a source of danger is by depicting them as a hazard to navigation, especially threatening to ships traveling from Earth to the outer parts of the Solar System and thus needing to pass the Asteroid Belt (or make a time- and fuel-consuming detour around it). In this context, asteroids serve the same role in space travel stories as reefs and underwater rocks in the older genre of seafaring adventure stories. And like such hazards, asteroids could also be used by bold outlaws to avoid pursuit. Representations of the Asteroid Belt in film tend to make it unrealistically cluttered with dangerous rocks, so dense that adventurous measures must be taken to avoid an impact, giving dramatic visual images which the true nearly empty space would not provide. One of the best-known examples of this is the Hoth system in The Empire Strikes Back.

text: If a reference direction from one side of the plane of reference to the other is defined, the two nodes can be distinguished. For geocentric and heliocentric orbits, the ascending node (or north node) is where the orbiting object moves north through the plane of reference, and the descending node (or south node) is where it moves south through the plane. In the case of objects outside the Solar System, the ascending node is the node where the orbiting secondary passes away from the observer, and the descending node is the node where it moves towards the observer.

text: Photometric observations of this asteroid gave a light curve with a period of 13.623 hours. The data was used to construct a model for the asteroid, revealing it to be a regular-shaped object, spinning about a pole with ecliptic coordinates (β, λ) = (+20°, 356°), although this is with an accuracy of only ±10°. The ratio of the major to minor axes lengths is roughly equal to 1.2. It is classified as an S-type asteroid and has an estimated size of 154.34 km. The spectrum of 354 Eleonora reveals the strong presence of the mineral Olivine, a relatively rarity in the asteroid belt.

text: With a visual magnitude of 17.3, Haumea is the third-brightest object in the Kuiper belt after Pluto and , and easily observable with a large amateur telescope. However, because the planets and most small Solar System bodies share a common orbital alignment from their formation in the primordial disk of the Solar System, most early surveys for distant objects focused on the projection on the sky of this common plane, called the ecliptic. As the region of sky close to the ecliptic became well explored, later sky surveys began looking for objects that had been dynamically excited into orbits with higher inclinations, as well as more distant objects, with slower mean motions across the sky. These surveys eventually covered the location of Haumea, with its high orbital inclination and current position far from the ecliptic.

text: Massive astrophysical compact halo object (MACHO) is any kind of astronomical body that might explain the apparent presence of dark matter in galaxy halos. A MACHO is a body composed of normal baryonic matter that emits little or no radiation and drifts through interstellar space unassociated with any planetary system. Since MACHOs are not luminous, they are hard to detect. MACHOs include black holes or neutron stars as well as brown dwarfs and unassociated planets. White dwarfs and very faint red dwarfs have also been proposed as candidate MACHOs.  The term was coined by astrophysicist Kim Griest.

text: This is a list of all confirmed gravitationally rounded objects in the Solar System. These objects all have a rounded, ellipsoidal shape due to the forces of their own gravity (hydrostatic equilibrium) and their sizes range from dwarf planets and moons to the planets and the sun. This list does not include any small Solar System bodies, but it does a sample of planetary-mass objects whose shape has yet to be accurately determined. The Sun's orbital characteristics are listed in relation to the Galactic Center, while all other objects are listed in order of their distance from the Sun.

text: The most primitive meteorites also contain a small amount of material (< 0.1%) which is now recognized to be presolar grains that are older than the Solar System itself, and which are derived directly from the remnants of the individual supernovae that supplied the dust from which the Solar System formed. These grains are recognizable from their exotic chemistry which is alien to the Solar System (such as matrixes of graphite, diamond, or silicon carbide). They also often have isotope ratios which are not those of the rest of the Solar System (in particular, the Sun), and which differ from each other, indicating sources in a number of different explosive supernova events. Meteorites also may contain interstellar dust grains, which have collected from non-gaseous elements in the interstellar medium, as one type of composite cosmic dust ("stardust")

text: Brown and his team also had been observing the dwarf planet  for approximately six months before its announced discovery by José Luis Ortiz Moreno and colleagues from the Sierra Nevada Observatory in Spain. Brown originally indicated his support for Ortiz's team being given credit for the discovery of Haumea. However, further investigation showed that a website containing archives of where Brown's team's telescopes had been pointed while tracking Haumea had been accessed eight times in the three days preceding Ortiz's announcement, by computers with IP addresses that were traced back to the website of the Instituto de Astrofísica de Andalucía (CSIC, Institute of Astrophysics of Andalusia), where Ortiz works, and to e-mail messages sent by Ortiz and his student. These website accesses came a week after Brown had published an abstract for an upcoming conference talk at which he had planned to announce the discovery of Haumea; the abstract referred to Haumea by a code that was the same code used in the online telescope logs; and the Andalusia computers had accessed the logs containing that code directly, as would be the case after an internet search, without going through the home page or other pages of the archives. When asked about this online activity, Ortiz responded with an email to Brown that suggested Brown was at fault for "hiding objects", and said that "the only reason why we are now exchanging e-mail is because you did not report your object." Brown says that this statement by Ortiz contradicts the accepted scientific practice of analyzing one's research until one is satisfied that it is accurate, then submitting it to peer review prior to any public announcement. However, the Minor Planet Center only needs precise enough orbit determination on the object in order to provide discovery credit, which Ortiz provided.

text: In her legend, Haumea's many children came from different parts of her body. The dwarf planet Haumea appears to be almost entirely made of rock, with only a superficial layer of ice; most of the original icy mantle is thought to have been blasted off by the impact that spun Haumea into its current high speed of rotation, where the material formed into the small Kuiper belt objects in Haumea's collisional family. There could therefore be additional outer moons, smaller than Namaka, that have not yet been detected. However, HST observations have confirmed that no other moons brighter than 0.25% of the brightness of Haumea exist within the closest tenth of the distance (0.1% of the volume) where they could be held by Haumea's gravitational influence (its Hill sphere). This makes it unlikely that any more exist.

text: Fictional planets in our Solar System beyond the orbit of Neptune have been employed many times as settings or references in science fiction. Following the general reception of Pluto as the ninth planet of the Solar System in 1930, a hypothetical additional planet was sometimes called a "tenth planet".  Since 1992, a very large number of objects have been found beyond Neptune; all the objects in the following list, however, are purely fictional. Common names for trans-Neptunian planets in fiction include Planet X, after a planet once believed to lie beyond Neptune, and Persephone (or Proserpina), after the wife of Pluto.

text: In October 2015, astronomer Jean-Luc Margot of the University of California Los Angeles proposed a metric for orbital zone clearance derived from whether an object can clear an orbital zone of extent 2√3 of its Hill radius in a specific time scale. This metric places a clear dividing line between the dwarf planets and the planets of the solar system. The calculation is based on the mass of the host star, the mass of the body, and the orbital period of the body. An Earth-mass body orbiting a solar-mass star clears its orbit at distances of up to 400 astronomical units from the star.  A Mars-mass body at the orbit of Pluto clears its orbit. This metric, which leaves Pluto as a dwarf planet, applies to both the Solar System and to extrasolar systems.

text: As a Death God, Pluto has a pact with Death that allows him to claim the souls of any worshipper of the Greco-Roman Gods, and order those under his command. He is capable of draining the energy and life-force from those that he touches, even other gods. The various Death Gods can either act as allies or competitors depending on the situation.  Pluto is more powerful within Hades than in other realms, due to his ability to commune with and manipulate the energies of the Underworld. On Earth, he can command armies of undead.

text: Initially, Ford used the Meteor nameplate in 1949 when it created a stand-alone marque of vehicles that used Ford bodies trimmed using unique parts for sale specifically in the Canadian marketplace. Meteors were produced and sold in Canada until 1961, and then reintroduced again from 1964 to 1976, after the US model using the name was discontinued.

text: In nearly all cases, comets are named after their discoverer(s), but in a few cases such as 2P/Encke and 27P/Crommelin they were named for a person who calculated their orbits (the orbit computers). The long-term orbits of comets are difficult to calculate because of errors in the known trajectory that accumulate with perturbations from the planets, and in the days before electronic computers some people dedicated their entire careers to this. Even so, quite a few comets were lost because their orbits are also affected by non-gravitational effects such as the release of gas and other material that forms the comet's coma and tail. Unlike a long-period comet, the next perihelion passage of a numbered periodic comet can be predicted with a high degree of accuracy.

text: Rojansky's original 1940 hypothesis was that perhaps the only bodies within the Solar System that could be antimatter were comets and meteoroids, all others being almost certainly normal matter. Experimental evidence gathered since then has not only borne out this restriction but has made the existence of actual antimatter comets and meteoroids themselves seem ever more unlikely. Gary Steigman, assistant professor of Astronomy at Yale University, observed in 1976 that space probes had proven — by the fact that they were not annihilated upon impact — that bodies such as Mars, Venus, and the Moon were not antimatter. He also noted that had any of the planets or similar bodies been antimatter, their interaction with the terrene solar wind and the sheer strength of the gamma ray emissions that would have resulted would have made them readily noticeable long since. He noted that not even antimatter cosmic rays had been found, with all of the nuclei found in studies having been uniformly terrene, the experimental data in several studies made from 1961 onwards by various people excluding the presence of a fractional antimatter composition of cosmic rays any larger than 10 of the total. Further, the uniformly terrene nature of the cosmic ray flux indicates that nowhere in the Milky Way are there any sources of heavier antimatter elements (such as carbon), since (although it is not proven) it is a likely assumption that they represent the overall composition of the entire galaxy. They are representative of the galaxy as a whole — goes the logic — and since they do contain terrene carbon and other atoms, but have not been observed to contain any antimatter atoms, therefore there is no reasonable source for extrasolar antimatter comets, meteoroids, or any other large scale heavy element objects to originate from, within this galaxy.

text: Comet Kohoutek is a long-period comet; its previous apparition was about 150,000 years ago, and its next apparition will be in about 75,000 years. At its apparition in 1973 it had a hyperbolic trajectory (e > 1) due to gravitational perturbations from giant planets. Due to its path, scientists theorized that Kohoutek was an Oort-cloud object. As such, it was believed that this was the comet's first visit to the inner Solar System, which would result in a spectacular display of outgassing. Infrared and visual telescopic study have led many scientists to conclude, in retrospect, that Kohoutek is actually an Edgeworth/Kuiper-belt object, which would account for its apparent rocky makeup and lack of outgassing.

text: After he causes Scratlantis to be sucked down the plughole, Scrat wanders through the landscape with a new acorn in hand. Inadvertently, he falls through into a cave and spots a place to stick his acorn in. Upon placing it, the whole cave melts, revealing that he is inside a spaceship (resembling the one inside the ice cave's walls in the first film). Scrat pulls the leaver that the acorn is on only for the ship to suddenly take off, the ship zooms into space and crashes into the Moon, causing it to hit several other planets causing them to bounce around and bump into each other as if they were billiard balls (the Moon is the cue ball) which ends up forming the Solar System which incidentally gives two planets new appearances (Jupiter's Great Red Spot is formed when Mars bumps into it, leaving a red splotch-like bruise on its surface; while Saturn is bumped into its rings as if it were a billiard ball falling into a pocket), as well as causing a green planet to be shot off into space and toward some constellations and two more extra planets to collide with each other, shattering both worlds and forming the Asteroid Belt.

text: After stealing a student's one month of allowance, Eros Magdayo meets a girl named Eris Jane Trinidad, who claims that she is his guardian angel. Disbelieving her, Eros tries hard to get away from her, with no success. Eris tries to convince him further, stating that she is already dead and it is her mission to change Eros' bad ways within a month. She further states that if they are able to complete the mission, Eros will be granted a wish, and Eris will be given the chance to live again. Still not convinced by her, Eros returns to his family's home, a place he rarely visits because of his being an adopted child. Much to his dismay, Eris tries to come to his home, having no place to settle in, with his older step-sister Risa letting her stay inside. While lamenting about Risa's inevitable death due to her illness, he thinks about Eris' claim of being able to grant him a wish, and wanting to wish for his sister to be healed. Thus Eros goes along with Eris to try to finish her mission within a month so that he could be granted his wish while giving Eris a chance to live again.

text: Pluto's orbit lay within this band and thus its planetary status was thrown into question.  Many scientists concluded that tiny Pluto should be reclassified as a minor planet, just as Ceres had been a century earlier. Mike Brown of the California Institute of Technology suggested that a "planet" should be redefined as "any body in the Solar System that is more massive than the total mass of all of the other bodies in a similar orbit." Those objects under that mass limit would become minor planets. In 1999, Brian G. Marsden of Harvard University's Minor Planet Center suggested that Pluto be given the minor planet number 10000 while still retaining its official position as a planet. The prospect of Pluto's "demotion" created a public outcry, and in response the International Astronomical Union clarified that it was not at that time proposing to remove Pluto from the planet list.

text: Pluto has five known moons: Charon (the largest, with a diameter just over half that of Pluto), Styx, Nix, Kerberos, and Hydra. Pluto and Charon are sometimes considered a binary system because the barycenter of their orbits does not lie within either body. The IAU has not formalized a definition for binary dwarf planets, and Charon is officially classified as a moon of Pluto. In September 2016, astronomers announced that the reddish-brown cap of the north pole of Charon is composed of tholins, organic macromolecules that may be ingredients for the emergence of life, and produced from methane, nitrogen and related gases released from the atmosphere of Pluto and transferred over about  distance to the orbiting moon.

text: His most notable contribution to Esperanto and its cause was when he was serving as the Australian Ambassador to the United Nations in 1977. NASA, the US space agency, had programmed the launch in that year of two space probes, Voyagers 1 and 2, which were designed to take and send back to earth images of the outer planets, then continue beyond the solar system after escaping the sun’s gravitational pull to become the first man-made objects to leave it.  NASA and the cosmologist Carl Sagan decided to create identical golden records to attach to each probe that were designed to tell the story of the Solar System, and mankind, should one of them ever come into contact with extraterritorial intelligent life. Engraved on each record was, among other things, a soundtrack containing a compilation of 54 peace greetings to the universe recorded in different languages by various UN delegates. Ralph succeeded in persuading the UN and NASA to accept a message in Esperanto. It is located third-last on track 3 of the golden records and says (translated):

text: Observations in 2004 revealed the presence of an inner belt containing silicate material at a distance of 6.4 AU from the star. Silicate material was also detected at 16 and 30 AU from the star, with a lack of dust between 6.4 and 16 AU providing evidence that a massive planet may be orbiting in this region. Magnesium-rich olivine has also been detected, strikingly similar to that found in the Solar System comets and different from the olivine found in Solar System asteroids. Olivine crystals can only form closer than 10 AU from the star; therefore they have been transported to the belt after formation, probably by radial mixing.

text: The Meteors are an English psychobilly band formed in 1980. Originally from London, England, they are often credited with giving the psychobilly subgenre—which fuses punk rock with rockabilly—its distinctive sound and style. Though the origins of psychobilly are debated, The Meteors are the first band to self-identify as psychobilly, and are often credited with the distinction of being the only "pure" psychobilly band among fans of the subgenre.

text: One problem that many of the Northeastern railroads faced was the fact that the railroad market was saturated for the dwindling rail traffic that remained. The NYC had to compete with its two biggest rivals: the Pennsylvania Railroad (PRR), and the Baltimore and Ohio Railroad (B&O), in addition to more moderate-size railroads such as the Delaware, Lackawanna, and Western Railroad (DLW), the Erie Railroad, the Reading Company, the Central Railroad of New Jersey, and the Lehigh Valley Railroad. Mergers of these railroads seemed a promising way for these companies to streamline operations and reduce the competition. The DL&W and Erie railroads had showed some success when they began merging their operations in 1956, finally leading to the formation of the Erie Lackawanna Railroad in 1960. Other mergers combined the Virginian Railway, Wabash Railroad, Nickel Plate Road and several others into the Norfolk and Western Railway (N&W) system, and the Baltimore and Ohio Railroad (B&O), Western Maryland Railroad (WM), and Chesapeake and Ohio Railway (C&O) combined with others to form the Chessie System. Heavy streamlining and reduction in passenger services led to the success of many of these mergers.

text: The current orbits of the members of the family cannot be accounted for by the formational collision alone. To explain the spread of the orbital elements, an initial velocity dispersion of ~400 m/s is required, but such a velocity spread should have dispersed the fragments much further. This problem applies only to Haumea itself; the orbital elements of all the other objects in the family require an initial velocity dispersion of ~140 m/s. To explain this mismatch in the required velocity dispersion, Brown and colleagues suggest that Haumea initially had orbital elements closer to those of the other members of the family and its orbit (especially the orbital eccentricity), changed after the collision. Unlike the other members of the family, Haumea is in a chaotic orbit, near the 7:12 resonance with Neptune, which would increase Haumea's eccentricity to its current value.

text: In Warframe, players control members of the Tenno, a race of ancient warriors who have awoken from centuries of cryosleep to find themselves at war with the Grineer, a race of militarized and deteriorated human clones, the Corpus, a mega-corporation with advanced robotics and laser technology, the Infested, disfigured victims of the Technocyte infection, and later the Sentients, an alien force of mechanical beings returning from the Tau system after being driven back centuries ago. To fight back, the Tenno use psionically controlled, biomechanical biosuits to channel their unique abilities — the eponymous Warframes. Later missions reveal that the Warframes are actually biomechanical shells which are connected the conscience of the actual Tenno, human children who were given unpredictable powers by the Void. Those powers led to them being demonized and they were exiled into stasis pods on the Moon. The Tenno and their Warframes were used by the Orokin Empire in a desperate fight against the Sentients and stopped their invasion. However, for unknown reasons, the former turned on the latter and caused the Empire to collapse. The Empire shattered with the remnants becoming the Grineer and the Corpus while the Tenno were placed in stasis until centuries later. Available missions are scattered across the planets of the solar system, the moons Phobos, Europa, Luna, and dwarf planets Pluto, Ceres, Eris and Sedna. Players can also access missions set in a pocket dimension known as The Void through completing junctions on other planets or through Void Fissures, small volatile rifts which react with acquirable Void Relics.

text: The seven largest natural satellites in the Solar System (those bigger than 2,500 km across) are Jupiter's Galilean moons (Ganymede, Callisto, Io, and Europa), Saturn's moon Titan, Earth's moon, and Neptune's captured natural satellite Triton. Triton, the smallest of these, has more mass than all smaller natural satellites together. Similarly in the next size group of nine natural satellites, between 1,000 km and 1,600 km across, Titania, Oberon, Rhea, Iapetus, Charon, Ariel, Umbriel, Dione, and Tethys, the smallest, Tethys, has more mass than all smaller natural satellites together. As well as the natural satellites of the various planets, there are also over 80 known natural satellites of the dwarf planets, minor planets and other small Solar System bodies. Some studies estimate that up to 15% of all trans-Neptunian objects could have satellites.

text: In May 2003 Popular Mechanics reported that Komerath had found a way to crush the rocks in the asteroid belts using electromagnetic waves and assemble them into radiation shields and structures where humans could live, among other purposes.The idea came to Komerath by analogy with the technique of "acoustic shaping", where sound waves can accurately position small objects such as beads into larger solid objects within a weightless environment.  In space, radio waves would take the place of sound waves. Although huge amounts of energy would be needed, solar power could be used and the approach would avoid the requirement to transport material from Earth.Komerath said "You don't go to investors and say 'I want to build a giant spinning cyclinder in space that would house 10,000 people'. You go and say 'I want to build a space-based economy'. It's a business model that will work only if there are a lot of people who will go broke at the same time if it fails".

text: The Kuiper belt, sometimes called the Edgeworth–Kuiper belt, is a region of the Solar System beyond the planets extending from the orbit of Neptune (at 30 AU) to approximately 55 AU from the Sun. It is similar to the asteroid belt, although it is far larger; 20 times as wide and 20–200 times as massive. Like the asteroid belt, it consists mainly of small bodies (remnants from the Solar System's formation) and at least one dwarf planet—Pluto, wchich may be geologically active. But while the asteroid belt is composed primarily of rock and metal, the Kuiper belt is composed largely of ices, such as methane, ammonia, and water. The objects within the Kuiper belt, together with the members of the scattered disc and any potential Hills cloud or Oort cloud objects, are collectively referred to as trans-Neptunian objects (TNOs).

text: Korolev received word about von Braun's 1956 Jupiter-C test, but thinking it was a satellite mission that failed, he expedited plans to get his own satellite in orbit. Since his R-7 was substantially more powerful than any of the American boosters, he made sure to take full advantage of this capability by designing Object D as his primary satellite. It was given the designation 'D', to distinguish it from other R-7 payload designations 'A', 'B', 'V', and 'G' which were nuclear weapon payloads. Object D dwarfed the proposed American satellites, by having a weight of , of which  would be composed of scientific instruments that would photograph the Earth, take readings on radiation levels, and check on the planet's magnetic field. However, things were not going along well with the design and manufacturing of the satellite, so in February 1957, Korolev sought and received permission from the Council of Ministers to create a prosteishy sputnik (PS-1), or simple satellite. The Council also decreed that Object D be postponed until April 1958. The new sputnik was a shiny sphere that would be a much lighter craft, weighing  and having a  diameter. The satellite would not contain the complex instrumentation that Object D had, but had two radio transmitters operating on different short wave radio frequencies, the ability to detect if a meteoroid were to penetrate its pressure hull, and the ability to detect the density of the Earth's thermosphere.

text: Some aspects of the definition are as yet difficult to apply outside the Solar System.  Techniques for identifying extrasolar objects generally cannot determine whether an object has "cleared its orbit", except indirectly via an orbit-clearing criterion.  The wording of the 2006 definition is heliocentric in its use of the word Sun instead of star or stars, and is thus not applicable to the numerous objects which have been identified in orbit around other stars. A separate "working" definition for extrasolar planets was, however, recommended by a working group of the IAU in 2003 and includes the criterion: "The minimum mass/size required for an extrasolar object to be considered a planet should be the same as that used in the Solar System."

It has changed my life." (The idea is mistaken—meteoroids are in space; meteorites have fallen to the ground.) The album's front cover, designed by Luke Insect, uses a thin-slice image of the Zagami meteorite from Mars. Pictures of other thin-sliced meteorites decorate the LP back cover and CD booklet.

text: Allendeite, ScZrO, is an oxide mineral. Allendeite was discovered in a small ultrarefractory inclusion within the Allende meteorite. This inclusion has been named ACM-1.  It is one of several scandium rich minerals that have been found in meteorites. Allendeite is trigonal, with a calculated density of 4.84 g/cm. The new mineral was found along with hexamolybdenum. These minerals, are believed to demonstrate conditions during the early stages of the Solar System, as is the case with many CV3 carbonaceous chondrites such as the Allende meteorite.  It is named after the Allende meteorite that fell in 1969 near Pueblito de Allende, Chihuahua, Mexico.

Its orbit is extremely eccentric, with an aphelion estimated at 937 AU and a perihelion at about 76 AU. This perihelion was the largest of that of any known Solar System object until the discovery of . When Sedna was discovered it was 89.6 AU from the Sun approaching perihelion, and was the most distant object in the Solar System observed. Eris was later detected by the same survey near aphelion at 97 AU. Only the orbits of some long-period comets extend farther than that of Sedna; they are too dim to be discovered except when approaching perihelion in the inner Solar System. Even as Sedna nears its perihelion in mid 2076, the Sun would appear merely as an extremely bright star-like pinpoint in its sky, 100 times brighter than a full moon on Earth (for comparison, the Sun appears from Earth to be roughly 400,000 times brighter than the full Moon), and too far away to be visible as a disc to the naked eye.

text: At the low altitudes at which Mir orbited there is a variety of space debris, consisting of everything from entire spent rocket stages and defunct satellites, to explosion fragments, paint flakes, slag from solid rocket motors, coolant released by RORSAT nuclear powered satellites, small needles, and many other objects. These objects, in addition to natural micrometeoroids, posed a threat to the station as they could puncture pressurised modules and cause damage to other parts of the station, such as the solar arrays. Micrometeoroids also posed a risk to spacewalking cosmonauts, as such objects could puncture their spacesuits, causing them to depressurise. Meteor showers in particular posed a risk, and, during such storms, the crews slept in their Soyuz ferries to facilitate an emergency evacuation should Mir be damaged.

text: Chondrules and calcium–aluminium-rich inclusions (CAIs) are spherical particles that make up chondritic meteorites and are believed to be the oldest objects in the solar system. Hence precise dating of these objects is important to constrain the early evolution of the solar system and the age of the earth. The U-Pb dating method can yield the most precise ages for early solar-system objects due to the optimal half-life of U. However, the absence of zircon or other uranium-rich minerals in chondrites, and the presence of initial non-radiogenic Pb (common Pb), rules out direct use of the U-Pb concordia method. Therefore, the most precise dating method for these meteorites is the Pb-Pb method, which allows a correction for common Pb.

text: At the time of the discovery of the then-planet Pluto in 1930 Lovecraft himself very casually suggested, in a letter to a friend, that Yuggoth might "probably" be the same as Pluto . Other writers have since claimed that it is actually an enormous trans-Neptunian world that orbits perpendicular to the ecliptic of the solar system.  The Italian astronomer Albino Carbognani has suggested that any planet discovered beyond Pluto might be named Yuggoth.

text: Beta Pictoris shows an excess of infrared emission compared to normal stars of its type, which is caused by large quantities of dust and gas (including carbon monoxide) near the star. Detailed observations reveal a large disk of dust and gas orbiting the star, which was the first debris disk to be imaged around another star. In addition to the presence of several planetesimal belts and cometary activity, there are indications that planets have formed within this disk and that the processes of planet formation may still be ongoing. Material from the Beta Pictoris debris disk is thought to be the dominant source of interstellar meteoroids in the Solar System.

text: The palladium isotope Pd decays by beta emission to Ag with a half-life of 6.5 million years. Iron meteorites are the only objects with a high-enough palladium-to-silver ratio to yield measurable variations in Ag abundance. Radiogenic Ag was first discovered in the Santa Clara meteorite in 1978. The discoverers suggest the coalescence and differentiation of iron-cored small planets may have occurred 10 million years after a nucleosynthetic event. Pd–Ag correlations observed in bodies that have clearly been melted since the accretion of the solar system must reflect the presence of unstable nuclides in the early solar system.

text: Erie is well connected to the Interstate Highway System. There are six "Erie exits" along Interstate 90, a major cross-country thoroughfare running from Boston to Seattle.  Erie is the northern terminus of Interstate 79, which travels south to Pittsburgh and, ultimately, West Virginia. The western terminus for Interstate 86, also called the "Southern Tier Expressway," is at Interstate 90 between Erie and North East, Pennsylvania. Interstate 86 continues east through New York to Binghamton. The Bayfront Connector runs from Interstate 90 in Harborcreek to the Bayfront Parkway and downtown Erie, along the east side of the city, then connects to Interstate 79 on the west side of the city. Major thoroughfares in the city include 12th Street, 26th Street, 38th Street and Peach Street. Peach is also a part of U.S. Route 19, whose northern terminus is in Erie and continues south eventually reaching the Gulf of Mexico. Other major routes running through Erie are Pennsylvania Route 5, known as the Seaway Trail and is made up of parts of 6th Street, 8th Street, 12th Street, and East Lake Road in the city, U.S. Route 20, which is 26th Street in the city. The city is divided between east and west by State Street.

text: The cause of the explosion is controversial, and still much disputed to this day. Although the cause of the explosion is the subject of debate, it is commonly believed to have been caused by the air burst of a large meteoroid or comet fragment at an altitude of 5–10 kilometres (3–6 miles) above the Earth's surface. Different studies have yielded varying estimates of the object's size, with general agreement that it was a few tens of metres across.

text: The rotation period of Makemake is estimated at 7.77 hours. Its lightcurve amplitude is small, only 0.03 mag. This was thought to be due to Makemake currently being viewed pole on from Earth; however, S/2015 (136472) 1's orbital plane (which is probably orbiting with little inclination relative to Makemake's equator due to tides resulting from its rapid rotation) is edge-on from Earth, implying that Makemake is really being viewed equator-on.

text: Of the many exoplanets discovered, most exoplanets have a higher orbital eccentricity than our solar system.  Exoplanets found with low orbital eccentricity, near circular orbits, are very close to its star and are tidal locked to the star, like planet Mercury. All eight planets in the Solar System have near-circular orbits.  The exoplanets discovered show that the solar system, with its unusually low eccentricity, is rare and unique. One theory attributes this low eccentricity to the high number of planets in the Solar System; another suggests it arose because of its unique asteroid belts. A few other multiplanetary systems have been found, but none resemble the solar system. The solar system has unique planetesimal systems, which led the planets to have near-circular orbits. Solar planetesimal systems include the asteroid belt, Hilda family, Kuiper belt, Hills cloud, and the Oort cloud. The exoplanet solar systems discovered have either no planetesimal systems or one very large planetesimal system. Low eccentricity is needed for habitability, especially advanced life. High multiplicity planet systems are much more likely to have habitable exoplanets.  The Grand tack hypothesis of the solar system also helps understand the near-circular orbits of the solar system and the other unique features of the solar system.

text: The Allende meteorite, which fell in 1969, contained abundant calcium–aluminium-rich inclusions (CAIs). These are very refractory materials and were interpreted as being condensates from a hot solar nebula. then discovered that the oxygen in these objects was enhanced in O by ~5% while the O/O was the same as terrestrial. This clearly showed a large effect in an abundant element that might be nuclear, possibly from a stellar source. These objects were then found to contain strontium with very low Sr/Sr indicating that they were a few million years older than previously analyzed meteoritic material and that this type of material would merit a search for Al.  Al is only present today in solar system materials as the result of cosmic reactions on unshielded materials at an extremely low level. Thus, any original Al in the early Solar system is now extinct.

text: With a density of 0.82 g/cm, assuming that the primary and satellite have the same density,  is one of the largest known solid objects in the Solar System that is less dense than water. Why this should be is not well understood, because objects of its size in the Kuiper belt often contain a fair amount of rock and are hence pretty dense. To have a similar composition to others large KBOs, it would have to be exceptionally porous, which is unlikely given the compactability of water ice. Hence, its density astonished astronomers.

text: Mike Brown counters these claims by saying that, far from not having cleared their orbits, the major planets completely control the orbits of the other bodies within their orbital zone. Jupiter may coexist with a large number of small bodies in its orbit (the Trojan asteroids), but these bodies only exist in Jupiter's orbit because they are in the sway of the planet's huge gravity. Similarly, Pluto may cross the orbit of Neptune, but Neptune long ago locked Pluto and its attendant Kuiper belt objects, called plutinos, into a 3:2 resonance, i.e., they orbit the Sun twice for every three Neptune orbits. The orbits of these objects are entirely dictated by Neptune's gravity, and thus, Neptune is gravitationally dominant.

text: The Minor Planet Center, which officially catalogs the objects in the Solar System, classifies Sedna as a scattered object. However, this grouping is heavily questioned, and many astronomers have suggested that it, together with a few other objects (e.g. ), be placed in a new category of distant objects named extended scattered disc objects (E-SDO), detached objects, distant detached objects (DDO), or scattered-extended in the formal classification by the Deep Ecliptic Survey.

text: There are two main classes of comet, short-period comets (also called ecliptic comets) and long-period comets (also called nearly isotropic comets). Ecliptic comets have relatively small orbits, below 10 AU, and follow the ecliptic plane, the same plane in which the planets lie. All long-period comets have very large orbits, on the order of thousands of AU, and appear from every direction in the sky. Oort noted that there was a peak in numbers of long-period comets with aphelia (their farthest distance from the Sun) of roughly 20,000 AU, which suggested a reservoir at that distance with a spherical, isotropic distribution. Those relatively rare comets with orbits of about 10,000 AU have probably gone through one or more orbits through the Solar System and have had their orbits drawn inward by the gravity of the planets.

text: The railroads themselves began to decline after the Great Depression, accelerating after World War II with the building of the Interstate Highway System and increased competition from trucking companies.  One of the first Class I railroads to shut down was the O&W, in 1957, leaving Port Jervis totally reliant on the Erie.  Only a few years later, in 1960, the Erie, also on a shaky financial footing, merged with Delaware, Lackawanna and Western Railroad to become the Erie Lackawanna.  In 1976, along with a number of other struggling railroads, such as the Penn Central, the Erie Lackawana became part of Conrail.  Since the breakup of Conrail, the trackage around Port Jervis has been controlled by Norfolk Southern. The decline of the railroads was an economic blow to Port Jervis, one it is still, as of 2011, recovering from.

text: The game's background story is only explained through the user manual. In the game's universe, humanity has colonized most planets in our galaxy, the Milky Way, and they now look towards expanding their reach by using an experimental travel technology called "Hyperzone Drive". However, a race of aliens who have already mastered that technology are currently invading planets at a quick pace, closing in on the Solar System. The invaders attack humanity's colony on Pluto and conquer it with little resistance, since human civilization doesn't have the technology to defend itself.

text: Planetary aberration is the combination of the aberration of light (due to Earth's velocity) and light-time correction (due to the object's motion and distance), as calculated in the rest frame of the Solar System. Both are determined at the instant when the moving object's light reaches the moving observer on Earth. It is so called because it is usually applied to planets and other objects in the Solar System whose motion and distance are accurately known.

text: Growing the star will increase its gravitational force, which increases the number of planets the solar system can have. They will also be able to attract solar systems composed of stars with lower mass than that of the player, or being attracted to stars with bigger mass. If both stars collide, they will be reduced to a lesser size within the same type of object. For example, if the player controls a small star and collides against a medium star, the player will be disintegrated while the AI-controlled star will be reduced to a small star. Being reduced from small star to life planet is not possible, as well as being reduced from small planet to asteroid. In these cases, the player is respawned, with random mass, close to the place where they collided.

text: Asteroids are differentiated from comets and meteoroids. In the case of comets, the difference is one of composition: while asteroids are mainly composed of mineral and rock, comets are composed of dust and ice. In addition, asteroids formed closer to the sun, preventing the development of the aforementioned cometary ice. The difference between asteroids and meteoroids is mainly one of size: meteoroids have a diameter of less than one meter, whereas asteroids have a diameter of greater than one meter. Finally, meteoroids can be composed of either cometary or asteroidal materials.

text: As other objects were discovered in the neighborhood of Ceres, it was realized that Ceres represented the first of a new class of objects. In 1802, with the discovery of 2 Pallas, William Herschel coined the term asteroid ("star-like") for these bodies, writing that "they resemble small stars so much as hardly to be distinguished from them, even by very good telescopes". As the first such body to be discovered, Ceres was given the designation 1 Ceres under the modern system of minor-planet designations. By the 1860s, the existence of a fundamental difference between asteroids such as Ceres and the major planets was widely accepted, though a precise definition of "planet" was never formulated.The 2006 debate surrounding Pluto and what constitutes a planet led to Ceres being considered for reclassification as a planet. A proposal before the International Astronomical Union for the definition of a planet would have defined a planet as "a celestial body that (a) has sufficient mass for its self-gravity to overcome rigid-body forces so that it assumes a hydrostatic equilibrium (nearly round) shape, and (b) is in orbit around a star, and is neither a star nor a satellite of a planet". Had this resolution been adopted, it would have made Ceres the fifth planet in order from the Sun. This never happened, however, and on 24 August 2006 a modified definition was adopted, carrying the additional requirement that a planet must have "cleared the neighborhood around its orbit". By this definition, Ceres is not a planet because it does not dominate its orbit, sharing it as it does with the thousands of other asteroids in the asteroid belt and constituting only about a third of the mass of the belt. Bodies that met the first proposed definition but not the second, such as Ceres, were instead classified as dwarf planets.

text: NEAs survive in their orbits for just a few million years. They are eventually eliminated by planetary perturbations, causing ejection from the Solar System or a collision with the Sun or a planet. With orbital lifetimes short compared to the age of the Solar System, new asteroids must be constantly moved into near-Earth orbits to explain the observed asteroids. The accepted origin of these asteroids is that asteroid-belt asteroids are moved into the inner Solar System through orbital resonances with Jupiter. The interaction with Jupiter through the resonance perturbs the asteroid's orbit and it comes into the inner Solar System. The asteroid belt has gaps, known as Kirkwood gaps, where these resonances occur as the asteroids in these resonances have been moved onto other orbits. New asteroids migrate into these resonances, due to the Yarkovsky effect that provides a continuing supply of near-Earth asteroids. The known asteroid with the greatest known chance of impacting Earth is  with a 1 in 16 chance of impacting Earth on 5 September 2095. Its 7-meter estimated diameter ensures that an impact would cause little damage.

text: "Meteorite" is a song by American singer and songwriter Mariah Carey from her fourteenth studio album, Me. I Am Mariah... The Elusive Chanteuse (2014). It was composed by Carey and Q-Tip. A disco track, it contains a sample of the recording "Goin' Up in Smoke" written by Allan Felder, Norman Harris, and Ron Tyson, all of whom received songwriting credits for "Meteorite" as a result. It also quotes an observation by Andy Warhol that everyone will achieve fame for 15 minutes. "Meteorite" garnered mostly positive reviews from music critics, many of whom praised the disco influence and highlighted it as one of the album's best tracks. The song peaked at number 70 on the international download chart in South Korea. Carey performed "Meteorite" at the 2014 World Music Awards, for which she was criticized for arriving over an hour late, and included it on the set list of her 2014 tour, The Elusive Chanteuse Show.

text: Besides Pluto, Makemake is the only other dwarf planet that was bright enough for Clyde Tombaugh to have possibly detected during his search for trans-Neptunian planets around 1930. At the time of Tombaugh's survey, Makemake was only a few degrees from the ecliptic, near the border of Taurus and Auriga, at an apparent magnitude of 16.0. This position, however, was also very near the Milky Way, and Makemake would have been almost impossible to find against the dense background of stars. Tombaugh continued searching for some years after the discovery of Pluto, but he did not find Makemake or any other trans-Neptunian objects.

text: The Hungaria asteroids are thought to be the remains of the hypothetical E-belt asteroid population.  The dispersal of most of that hypothetical E-belt might have been caused by the outwards migration of the giant planets of the Solar System according to simulations done under the Nice model—and these dispersed E-Belt asteroids might in turn have been the impactors of the Late Heavy Bombardment.

text: Solar conjunction occurs when a planet or other solar system object is on the opposite side of the sun from the Earth.  From an Earth reference, the sun will pass between the Earth and the object.

text: In the partial lists, numbered minor planets (MPs) are categorized into one of 8 distinct orbital groups. These are the near-Earth asteroids, the Mars-crossing asteroids, the inner-, middle- and outer main-belt asteroids (MBA), the Jupiter trojans, the centaurs and the trans-Neptunian objects. A minor planet's orbital group is represented by the background color of the table row . This classification is exclusively based on the body's relevant orbital elements, that is, its semi-major axis (a) and eccentricity (e). From these elements its perihelion (q) and aphelion (Q) can be derived.

text: Once again, the player is stranded on a planet, Eris, with an inoperable spacecraft. Unlike the first game, however, the scope of Damocles is considerably widened, offering the player an entire solar system to explore (the Gamma System; the player's original destination before the Interlude on Targ). There is also a race-against-time element to the game as a comet, the eponymous Damocles (a reference the Sword of Damocles), is hurtling towards Eris. The player is encouraged to both escape Eris and find a means to prevent Damocles from destroying the planet, if possible without destroying the comet. Although an obvious, but destructive, solution exists, Damocles has no fewer than five distinct solutions.

text: The term dwarf planet was adopted in 2006 as part of a three-way categorization of bodies orbiting the Sun, brought about by an increase in discoveries of objects farther away from the Sun than Neptune that rivaled Pluto in size, and finally precipitated by the discovery of an even more massive object, Eris. The exclusion of dwarf planets from the roster of planets by the IAU has been both praised and criticized; it was said to be the "right decision" by astronomer Mike Brown, who discovered  and other new dwarf planets, but has been rejected by Alan Stern, who had coined the term dwarf planet in April 1991.

text: "The symbols in the patch refer to the three major areas of investigation in the mission. The tree represents man's natural environment and refers to the objective of advancing the study of earth resources. The hydrogen atom, as the basic building block of the universe, represents man's exploration of the physical world, his application of knowledge, and his development of technology. Since the sun is composed primarily of hydrogen, the hydrogen symbol also refers to the Solar Physics mission objectives. The human silhouette represents mankind and the human capacity to direct technology with a wisdom tempered by his regard for his natural environment. It also relates to the Skylab medical studies of man himself. The rainbow, adopted from the Biblical story of the Flood, symbolizes the promise that is offered to man. It embraces man and extends to the tree and hydrogen atom, emphasizing man's pivotal role in the conciliation of technology with nature by a humanistic application of our scientific knowledge." Some versions of the patch included a comet in the top curve because of studies made of the comet Kohoutek.

text: There are also forces external to Earth itself that affect Earth’s climate. Two examples of these external forces are meteors/asteroids becoming meteorites and striking the surface of the earth, and geomagnetic storms from the sun affecting the earth. Asteroids only about two kilometers in diameter, according to Young’s paper referencing original author Michael Paine, can cause craters in Earth’s surface about 40 kilometers in diameter. Such an impact could throw enormous quantities of dust into the sky, blocking out the sun and causing significant climate changes, somewhat similar in effect to a gigantic volcanic eruption. Among other things, meteorites striking Earth also “affect sea level, rainfall, temperature, ocean currents, and atmospheric circulation”. Asteroids and meteors are not, however, the only external forces to affect Earth climate change. Variations in solar output can also bring about climate change on the Earth. More specifically, varying amounts of sun activity, including sunspots, solar flares, solar wind, and massive solar radiation, can all be grouped together as geomagnetic storms, which together, act to affect Earth’s climate. Our sun has a solar activity cycle of about 11 years. During which time, the sun gets sunspots, shoots off solar flares, and blasts earth with solar wind and geomagnetic activity. Despite the appearance that these events seem random, they do overall follow a fairly steady cycle of approximately 11 years. The difference in average solar irradiation received by the earth due to these ‘random’ events, though, is only about 0.1 percent. Overall, the total irradiation generated by the sun, and received by the earth is a major factor affecting Earth climate. The total solar irradiation received by Earth’s surface can be calculated mathematically. This can be done through the following equation:

text: During his public speech about the appearance of the comet, Augustus specified that he himself, the new ruler of the world, was born politically at the very time his father Julius Caesar appeared as a comet in the sky of Rome. His father was announcing the political birth of his adoptive son; he was the one  born under the comet and whom the appearance of the comet was announcing. Other messianic prophecies about Augustus are related by Suetonius, including the story of the massacre of the innocents conceived in order to kill the young Octavius soon after his own birth. Augustus wanted to be considered the real subject of any kind of Messianic prophecies and accounts. Later during his reign, he ordered that all other books of prophecies and Messianic accounts be gathered and destroyed. The temple therefore ended up as representing both Julius Caesar as a deified being and Augustus himself as the newborn under the comet. The comet star itself was an object of public worship.

text: NWA 7034 is the first Martian meteorite that is a breccia and does not fall in any of the known Martian meteorite groups (shergottite, nakhlite, chassignite and ALH 84001). NWA 7034 was classified as an ungrouped planetary achondrite until the Meteoritical Society approved the new designation "Martian (basaltic breccia)" in January 2013. The iron/manganese ratio is consistent with that of other Martian meteorites, but the oxygen isotopes do not correlate with a Martian origin. The change in oxygen isotope ratios could be explained by removal or addition of heavier or lighter isotopes, or by mixing with a mass with a different isotopic ratio. This could happen during aqueous alteration of the Martian crust. Another explanation would be an isotopic contamination of the Martian crust during impact brecciation.

text: Meteoroid collisions with solid Solar System objects, including the Moon, Mercury, Callisto, Ganymede and most small moons and asteroids, create impact craters, which are the dominant geographic features of many of those objects. On other planets and moons with active surface geological processes, such as Earth, Venus, Mars, Europa, Io and Titan, visible impact craters may become eroded, buried or transformed by tectonics over time. In early literature, before the significance of impact cratering was widely recognised, the terms cryptoexplosion or cryptovolcanic structure were often used to describe what are now recognised as impact-related features on Earth. Molten terrestrial material ejected from a meteorite impact crater can cool and solidify into an object known as a tektite. These are often mistaken for meteorites.

Opportunity had been sent to examine the heat shield after exiting the crater Endurance. This was the first meteorite found on another planet and the third found on another Solar System body — two others, the millimeter-sized Bench Crater and Hadley Rille, were found on the Moon.

text: Heat in a solar thermal system is guided by five basic principles: heat gain; heat transfer; heat storage; heat transport; and heat insulation. Here, heat is the measure of the amount of thermal energy an object contains and is determined by the temperature, mass and specific heat of the object. Solar thermal power plants use heat exchangers that are designed for constant working conditions, to provide heat exchange. Copper heat exchangers are important in solar thermal heating and cooling systems because of copper’s high thermal conductivity, resistance to atmospheric and water corrosion, sealing and joining by soldering, and mechanical strength. Copper is used both in receivers and in primary circuits (pipes and heat exchangers for water tanks) of solar thermal water systems.

text: The object of the game is to destroy all the asteroids which have a set speed at which they fly through the Sector. Asteroids come in varying sizes, and when shot, larger asteroids break into multiple smaller ones. Only shooting the smallest ones will actually remove them from the Sector. Asteroids also come in different types. Normal asteroids don't contain anything, but red asteroids can contain power-ups in the form of Power Crystals that are released by completely destroying asteroids. Crystals decay over time. Popcorn Asteroids require several hits, which expands their size, and eventually makes them stop spinning. They can't be destroyed, but stopping them is enough to finish each Sector. Egg asteroids contain leeches which home in on the user's ship and suck out its energy. They can be shot and destroyed. Finally there are Seeker asteroids which home in on the player's ship after being shot.

text: Short-period comets have orbits lasting less than two hundred years. Long-period comets have orbits lasting thousands of years. Short-period comets are thought to originate in the Kuiper belt, whereas long-period comets, such as Hale–Bopp, are thought to originate in the Oort cloud. Many comet groups, such as the Kreutz Sungrazers, formed from the breakup of a single parent. Some comets with hyperbolic orbits may originate outside the Solar System, but determining their precise orbits is difficult. Old comets that have had most of their volatiles driven out by solar warming are often categorised as asteroids.

text: Most comets are small Solar System bodies with elongated elliptical orbits that take them close to the Sun for a part of their orbit and then out into the further reaches of the Solar System for the remainder. Comets are often classified according to the length of their orbital periods: The longer the period the more elongated the ellipse.

text: Because Eris appeared to be larger than Pluto, NASA initially described it as the Solar System's tenth planet. This, along with the prospect of other objects of similar size being discovered in the future, motivated the International Astronomical Union (IAU) to define the term planet for the first time. Under the IAU definition approved on August 24, 2006, Eris is a "dwarf planet", along with objects such as Pluto, Ceres, Haumea and Makemake, thereby reducing the number of known planets in the Solar System to eight, the same as before Pluto's discovery in 1930. Observations of a stellar occultation by Eris in 2010 showed that its diameter was , not significantly different from that of Pluto. After New Horizons measured Pluto's diameter as  in July 2015, it was determined that Eris is slightly smaller in diameter than Pluto.

text: The small mass of Mars the low mass asteroid belt may be the result of pebble accretion becoming less efficient as the density of gas in the protoplanetary disk decreases. The protoplanetary disk from which the Solar System formed is believed to have had a surface density that decreased with distance from the Sun and have been flared, with an increasing thickness with distance from the Sun. As a result, the density of the gas and the aerodynamic drag felt by pebbles embedded in the disk would have decreased significantly with distance. If the pebbles were large the efficiency of pebble accretion would decline with distance from the Sun as the aerodynamic drag becomes too weak for the pebbles to be captured during encounters with the largest objects. An object that grows rapidly at Earth's orbital distance would only grow slowly in Mars's orbit and very little in the asteroid belt. The formation of Jupiter's core could also reduce the mass of the asteroid belt by crating a gap in the pebble disk and halting the inward drift of pebbles from beyond the ice line. Objects in the asteroid belt would then be deprived of pebbles early while objects in the terrestrial region continued to accrete pebbles that drifted in from the asteroid region.

text: Still others confuse Nibiru with Sedna (90377 Sedna) or Eris (136199 Eris), trans-Neptunian objects discovered by Mike Brown in 2003 and 2005 respectively. However, despite having been described as a "tenth planet" in an early NASA press release, Eris (Then known only as 2003 UB) is now classified as a dwarf planet. Only slightly more massive than Pluto, Eris has a well-determined orbit that never takes it closer than 5.5 billion km from the Earth. Sedna is slightly smaller than Pluto, and never comes closer to Earth than 11.4 billion km. Mike Brown believes the confusion results from both the real Eris and the imaginary Nibiru having extremely elliptical orbits.

text: Though life is confirmed only on Earth, many think that extraterrestrial life is not only plausible, but probable or inevitable. Other planets and moons in the Solar System and other planetary systems are being examined for evidence of having once supported simple life, and projects such as SETI are trying to detect radio transmissions from possible alien civilizations. Other locations within the Solar System that may host microbial life include the subsurface of Mars, the upper atmosphere of Venus, and subsurface oceans on some of the moons of the giant planets.Beyond the Solar System, the region around another main-sequence star that could support Earth-like life on an Earth-like planet is known as the habitable zone. The inner and outer radii of this zone vary with the luminosity of the star, as does the time interval during which the zone survives. Stars more massive than the Sun have a larger habitable zone, but remain on the main sequence for a shorter time interval. Small red dwarfs have the opposite problem, with a smaller habitable zone that is subject to higher levels of magnetic activity and the effects of tidal locking from close orbits. Hence, stars in the intermediate mass range such as the Sun may have a greater likelihood for Earth-like life to develop. The location of the star within a galaxy may also affect the likelihood of life forming. Stars in regions with a greater abundance of heavier elements that can form planets, in combination with a low rate of potentially habitat-damaging supernova events, are predicted to have a higher probability of hosting planets with complex life. The variables of the Drake equation are used to discuss the conditions in planetary systems where civilization is most likely to exist. Use of the equation to predict the amount of extraterrestrial life, however, is difficult; because many of the variables are unknown, the equation functions as more of a mirror to what its user already thinks. As a result, the number of civilizations in the galaxy can be estimated as low as 9.1 x 10^-11 or as high as 156 million; for the calculations, see Drake equation.

Use of the equation to predict the amount of extraterrestrial life, however, is difficult; because many of the variables are unknown, the equation functions as more of a mirror to what its user already thinks. As a result, the number of civilizations in the galaxy can be estimated as low as 9.1 x 10^-11 or as high as 156 million; for the calculations, see

text: At the beginning of the game, the player accumulates mass by colliding their asteroid against other asteroids until enough mass has been gathered to become a small planet. From there, the player has to absorb other asteroids to make their planet grow enough to become a life planet; crashing against other objects will decrease the player's mass. At this point, life forms will evolve in the planet, creating spaceships, planetary shields and cannons. If the player wishes, they can accumulate more mass until their planet becomes a star. Life forms will disappear, but the player will be able to attract planets to form a solar system, further grow the star by absorbing other planets, or a combination of both. The player can also create multi-star systems by selecting planets from their system and make them absorb asteroids until they become another star.

Searching for biological remains of the precursors to life, whether ancient or currently existing, would be far easier on an uncontaminated planet. This would similarly apply to searches for DNA sequences on Mars. Life on other planets could have a common origin with Earth life, since in the early Solar System there was much exchange of material between the planets which could have transferred life as well. If so it might be based on DNA too.

text: Reynolds' astronomical research has been primarily focused on Solar System objects, as well as meteoritics. He has led expeditions around the world for numerous total solar eclipses, meteorite crater research, and meteorite recoveries. He worked with Meade Instruments in 2005 to develop, curate, and create Meade’s MeteoriteKit, a special set of meteorites, tektites, and impactites.

text: Moons in retrograde orbits cannot form in the same region of the solar nebula as the planets they orbit, so Triton must have been captured from elsewhere. It might therefore have originated in the Kuiper belt, a ring of small icy objects extending outwards from just inside the orbit of Neptune to about 50 AU from the Sun. Thought to be the point of origin for the majority of short-period comets observed from Earth, the belt is also home to several large, planet-like bodies including Pluto, which is now recognized as the largest in a population of Kuiper belt objects (the plutinos) locked in orbital step with Neptune. Triton is only slightly larger than Pluto and nearly identical in composition, which has led to the hypothesis that the two share a common origin.

text: The main-belt comets are unique in that they have flat (within the plane of the planets' orbits), approximately circular (small eccentricity), asteroid-like orbits, and not the elongated, often tilted orbits characteristic of all other comets. Because (118401) LINEAR can generate a coma (produced by vapour boiled off the comet), it must be an icy asteroid. When a typical comet approaches the Sun, its ice heats up and sublimates (changes directly from ice to gas), venting gas and dust into space, creating a tail and giving the object a fuzzy appearance. Far from the Sun, sublimation stops, and the remaining ice stays frozen until the comet's next pass close to the Sun. In contrast, objects in the asteroid belt have essentially circular orbits and are expected to be mostly baked dry of ice by their confinement to the inner Solar System (see extinct comet).

text: B-type asteroids are a relatively uncommon type of carbonaceous asteroid, falling into the wider C-group. In the asteroid population, B-class objects can be found in the outer asteroid belt, and also dominate the high-inclination Pallas family which includes the second-largest asteroid 2 Pallas. They are thought to be primitive,  volatile-rich remnants from the early Solar System. There are 65 known B-type asteroids in the SMASS classification, and 9 in the Tholen classification as of March 2015.

text: Since microlensing observations do not rely on radiation received from the lens object, this effect therefore allows astronomers to study massive objects no matter how faint.  It is thus an ideal technique to study the galactic population of such faint or dark objects as brown dwarfs, red dwarfs, planets, white dwarfs, neutron stars, black holes, andmassive compact halo objects. Moreover, the microlensing effect is wavelength-independent, allowing use of distant source objects that emit any kind of electromagnetic radiation.

text: Halley's orbital period over the last 3 centuries has been between 75–76 years, although it has varied between 74–79 years since 240 BC. Its orbit around the Sun is highly elliptical, with an orbital eccentricity of 0.967 (with 0 being a circle and 1 being a parabolic trajectory). The perihelion, the point in the comet's orbit when it is nearest the Sun, is just 0.6 AU. This is between the orbits of Mercury and Venus. Its aphelion, or farthest distance from the Sun, is 35 AU (roughly the distance of Pluto). Unusual for an object in the Solar System, Halley's orbit is retrograde; it orbits the Sun in the opposite direction to the planets, or, clockwise from above the Sun's north pole. The orbit is inclined by 18° to the ecliptic, with much of it lying south of the ecliptic. (Because it is retrograde, the true inclination is 162°). Due to the retrograde orbit, it has one of the highest velocities relative to the Earth of any object in the Solar System. The 1910 passage was at a relative velocity of 70.56 km/s (157,838 mph or 254,016 km/h). Because its orbit comes close to Earth's in two places, Halley is associated with two meteor showers: the Eta Aquariids in early May, and the Orionids in late October. Halley is the parent body to the Orionids. Observations conducted around the time of Halley's appearance in 1986 suggested that the comet could additionally perturb the Eta Aquarid meteor shower, although it might not be the parent of that shower.

He specializes in the study of comets, in particular calculating their orbits and making predictions about when periodic comets will return for another perihelion approach.  It is considerably more difficult to predict the orbits of comets than of other types of Solar System objects, since their orbits are susceptible not only to perturbations from the planets but also to non-gravitational forces due to the release of gaseous material in the form of a comet's coma and tail.

text: Prior to Biot's thorough investigation of the meteorites that fell near l'Aigle, France in 1803, very few truly believed that rocks found on Earth could have extraterrestrial origins. There were anecdotal tales of unusual rocks found on the ground after fireballs had been seen in the sky, but such stories were often dismissed as fantasy. Serious debate concerning the unusual rocks began in 1794 when German physicist Chladni published a book claiming that rocks had an extraterrestrial origin (Westrum). Only after Biot was able to analyze the rocks at l'Aigle was it commonly accepted that the fireballs seen in the sky were meteors falling through the atmosphere. Since Biot's time, analysis of meteorites has resulted in accurate measurements of the chemical composition of the solar system. The composition and position of meteors in the solar system have also given astronomers clues as to how the solar system formed.

text: Impact craters provide evidence of past impacts on other planets in the Solar System, including possible interplanetary terrestrial impacts. Without carbon dating, other points of reference are used to estimate the timing of these impact events. Mars provides some significant evidence of possible interplanetary collisions. The North Polar Basin on Mars is speculated by some to be evidence for a planet-sized impact on the surface of Mars between 3.8 and 3.9 billion years ago, while Utopia Planitia is the largest confirmed impact and Hellas Planitia is the largest visible crater in the Solar System. The Moon provides similar evidence of massive impacts, with the South Pole–Aitken basin being the biggest. Mercury's Caloris Basin is another example of a crater formed by a massive impact event. Rheasilvia on Vesta is an example of a crater formed by an impact capable of, based on ratio of impact to size, severely deforming a planetary-mass object. Impact craters on the moons of Saturn such as Engelier and Gerin on Iapetus, Mamaldi on Rhea and Odysseus on Tethys and Herschel on Mimas form significant surface features.

text: Atira asteroids or Apohele asteroids, also known as Interior-Earth Objects (IEOs), are asteroids, whose orbits are entirely confined within Earth's orbit, that is, their orbit has an aphelion (farthest point from the Sun) smaller than Earth's perihelion (nearest point to the Sun), which is 0.983 astronomical units (AU). Atira asteroids are by far the smallest group of near-Earth objects, compared to the Aten, Apollo and Amor asteroids.
