text: With a semimajor axis of 2.628, the asteroid is orbiting between the 3:1 and 5:2 Kirkwood gaps in the main belt. Its orbital eccentricity is larger than the median value of 0.07 for the main belt, and the inclination is larger than the median of below 4°. But most of the main-belt asteroids have an eccentricity of no more than 0.4 and an inclination of up to 30°, so the orbit of 23 Thalia is not unusual for a main-belt asteroid.

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.

Transportation from Mars or the Moon to Ceres would be even more energy-efficient than transportation from Earth to the Moon.

text: The Origins, Spectral Interpretation, Resource Identification, Security, Regolith Explorer (OSIRIS-REx) is a NASA asteroid study and sample return mission. The launch occurred on 8 September 2016. Its mission is to study asteroid 101955 Bennu, a carbonaceous asteroid, and return a sample to Earth in 2023 for detailed analysis. The material returned is expected to enable scientists to learn more about the formation and evolution of the Solar System, its initial stages of planet formation, and the source of organic compounds that led to the formation of life on Earth. If successful, OSIRIS-REx will be the first US spacecraft to return samples from an asteroid.

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: However, we do see evidence for asteroidal space weathering.  For years there had been a so-called "conundrum" in the planetary science community because, in general, the spectra of asteroids do not match the spectra of our collection of meteorites. Particularly, the spectra of S-type asteroids, did not match the spectra of the most abundant type of meteorites, ordinary chondrites (OCs). The asteroid spectra tended to be redder with a steep curvature in the visible wavelengths. However, Binzel et al. have identified near Earth asteroids with spectral properties covering the range from S-type to spectra similar to those of OC meteorites, suggesting an ongoing process is occurring that can alter the spectra of OC material to look like S-type asteroids. There is also evidence of regolith alteration from Galileo's flybys of Gaspra and Ida showing spectral differences at fresh craters. With time, the spectra of Ida and Gaspra appear to redden and lose spectral contrast. Evidence from NEAR Shoemaker's x-ray measurements of Eros indicate an ordinary chondrite composition despite a red-sloped, S-type spectrum, again suggesting that some process has altered the optical properties of the surface. Results from the Hayabusa spacecraft at the asteroid Itokawa, also ordinary chondrite in composition, shows spectral evidence of space weathering.  In addition, definitive evidence of space weathering alteration has been identified in the grains of soil returned by the Hayabusa spacecraft.  Because Itokawa is so small (550 m diameter), it was thought that the low gravity would not allow for the development of a mature regolith, however, preliminary examination of the returned samples reveals the presence of nanophase iron and other space weathering effects on several grains.  In addition, there is evidence that weathering patinas can and do develop on rock surfaces on the asteroid.  Such coatings are likely similar to the patinas found on lunar rocks.

text: The terrestrial Planet V hypothesis was later examined by Ramon Brasser and Alessandro Morbidelli. Their work was the first to focus on the magnitude of the bombardment caused by Planet V. Brasser and Morbidelli calculated that to create the Late Heavy Bombardment Planet V would have to remove 95% of the pre-LHB main asteroid belt or 98% of the inner asteroid belt (semi-major axis < 2.5 AU). Depleting the main asteroid belt by 95% with a 0.5 Mars-mass Planet V was found to require it remain in an orbit crossing the entire asteroid belt for 300 Million years. This orbital evolution was not observed in any simulations, Planet V typically entered an Earth-crossing orbit resulting in a short dynamic lifetime before entering such an orbit. In a few percent of simulations Planet V remained in the inner belt long enough to produce the LHB. However, producing the LHB from the inner asteroid belt would require the inner asteroid belt to have begun with 4–13 times the mass, and 10-24 time the orbital density, as the rest of the asteroid belt.

text: In earlier works, asteroids provided grist for theories as to their origin – specifically, the theory that the asteroids are remnants of an exploded planet. This naturally leads to SF plot-lines dealing with the possibility that the planet had been inhabited, and if so – that the inhabitants caused its destruction themselves, by war or gross environmental mismanagement. A further extension is from the past of the existing asteroids to the possible future destruction of Earth or other planets and their rendering into new asteroids.

text: The perihelion secular resonance between asteroids and Saturn (ν = g − g) helps shape the asteroid belt. Asteroids which approach it have their eccentricity slowly increased until they become Mars-crossers, at which point they are usually ejected from the asteroid belt by a close pass to Mars. This resonance forms the inner and "side" boundaries of the asteroid belt around 2 AU, and at inclinations of about 20°.

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.

text: The asteroid's orbit also undergoes a slow, back-and-forth twist over multiple decades. "The asteroid's loops around Earth drift a little ahead or behind from year to year, but when they drift too far forward or backward, Earth's gravity is just strong enough to reverse the drift and hold onto the asteroid so that it never wanders farther away than about 100 times the distance of the moon," said Chodas. "The same effect also prevents the asteroid from approaching much closer than about 38 times the distance of the moon. In effect, this small asteroid is caught in a little dance with Earth."

text: The majority of known asteroids orbit within the asteroid belt between the orbits of Mars and Jupiter, generally in relatively low-eccentricity (i.e. not very elongated) orbits. This belt is now estimated to contain between 1.1 and 1.9 million asteroids larger than  in diameter, and millions of smaller ones. These asteroids may be remnants of the protoplanetary disk, and in this region the accretion of planetesimals into planets during the formative period of the Solar System was prevented by large gravitational perturbations by Jupiter.

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: The rapid traverse of resonances through the asteroid belt leaves its population and the overall distribution of its orbital elements largely preserved. The asteroid belt's depletion, the mixing of its taxonomical classes, and the excitation of its orbits, yielding a distribution of inclinations peaked near 10° and eccentricities peaked near 0.1, therefore must have occurred earlier. These may be the product of Jupiter's Grand Tack, provided that a few hundred million years elapsed between it and the Nice model instability for interactions with the terrestrial planets to remove an excess of higher eccentricity asteroids. Gravitational stirring by planetary embryos embedded in the asteroid belt could also produce its depletion, mixing, and excitation. However, most if not all of the embryos must have been lost before the instability. An initially small mass asteroid belt could have its inclinations and eccentricities excited by secular resonances that hopped across the asteroid belt if Jupiter's and Saturn's orbits became chaotic while in resonance.

text: Many databases, for instance the JPL Small-Body Database (JPL SBDB), only list asteroids with a perihelion greater than 1.3 AU as Mars-crossers. An asteroid with a perihelion less than this is classed as a near-Earth object even though it is crossing the orbit of Mars as well as crossing (or coming near to) that of Earth. Nevertheless, these objects are listed on this page. A grazer is an object with a perihelion below the aphelion of Mars (1.67 AU) but above the Martian perihelion (1.38 AU). The JPL SBDB lists 13,500 Mars-crossing asteroids (MCAs). Only 18 MCAs are brighter than absolute magnitude (H) 12.5, which typically makes these asteroids with H<12.5 more than 13 km in diameter depending on the albedo. The smallest known MCAs have an absolute magnitude (H) of around 24 and are typically less than 100 meters in diameter.

text: None of the asteroids in the outer part of the asteroid belt can ever attain this brightness. Even Hygiea and Interamnia rarely reach magnitudes of above 10.0. This is due to the different distribution of spectral types within different sections of the asteroid belt being such that the highest-albedo asteroids are all concentrated closer to Mars, and much lower albedo C and D types being common in the outer belt.

text: 243 Ida () is an asteroid in the Koronis family of the asteroid belt. It was discovered on 29 September 1884 by Austrian astronomer Johann Palisa and named after a nymph from Greek mythology. Later telescopic observations categorized Ida as an S-type asteroid, the most numerous type in the inner asteroid belt. On 28 August 1993, Ida was visited by the unmanned Galileo spacecraft, while en route to Jupiter. It was the second asteroid visited by a spacecraft and the first found to have a natural satellite.

text: The trains took them through a tunnel into the Columbiad Cannon. As the blast-off occurred, trains were suddenly propelled out of the Columbiad to the top of the dome. The space travel started with riders crossing asteroid fields until they got swallowed by Colonel Impey Barbicane's Bluemoon Mining Machine, an industrial space machine built by the President of the Gun Club to extract mineral resources from asteroids. Escaping the danger of this device, trains headed to a huge asteroid which they crossed through a small fissure. This journey came afterwards to the climax of the ride, the Moon itself (with a smiling face, as seen in Georges Méliès' 1902 movie adaptation of the novel). On the right, one could notice that Jules Verne himself, with the proper equipment, had landed on a nearby asteroid. Then trains headed back to Earth, crossing other asteroid fields. When riders reached the atmosphere, bolts and light rays were visible around the train as it heated up. Trains finally entered the Electro-de-Velocitor, a machine that stopped them suddenly so that their speed would be reduced when they headed back to the station.

text: According to the survey carried out by the NEOWISE mission of NASA's Wide-field Infrared Survey Explorer, the asteroid measures 3.5 kilometers in diameter and its surface has a very high albedo of 0.39. The Collaborative Asteroid Lightcurve Link (CALL) disagrees with the findings by the space-based mission and assumes a standard albedo for carbonaceous asteroids of 0.057, with a correspondingly larger diameter of 8.0 kilometers. As with 1696 Nurmela, another member of the Baptistina family, CALL assumes this asteroid's composition (also see carbonaceous chondrites) to differ significantly from the much brighter asteroid 298 Baptistina, which is considered to be an interloper in its own family.

text: The albedos of planets, satellites and asteroids can be used to infer much about their properties. The study of albedos, their dependence on wavelength, lighting angle ("phase angle"), and variation in time comprises a major part of the astronomical field of photometry. For small and far objects that cannot be resolved by telescopes, much of what we know comes from the study of their albedos. For example, the absolute albedo can indicate the surface ice content of outer Solar System objects, the variation of albedo with phase angle gives information about regolith properties, whereas unusually high radar albedo is indicative of high metal content in asteroids.

text: M-type asteroids are asteroids of partially known composition; they are moderately bright (albedo 0.1–0.2). Some, but not all, are made of nickel–iron, either pure or mixed with small amounts of stone. These are thought to be pieces of the metallic core of differentiated asteroids that were fragmented by impacts, and are thought to be the source of iron meteorites. M-type asteroids are the third most common asteroid type.

text: Several asteroids have collided with earth in recent geological history. The Chicxulub asteroid, for example, is theorized to have caused the extinction of the non-avian dinosaurs 66 million years ago at the end of the Cretaceous. If such an object struck Earth it could have a serious impact on civilization. It is even possible that humanity would be completely destroyed. For this to occur, the asteroid would need to be at least  in diameter, but probably between 3 and 10 km (2–6 miles). Asteroids with a 1 km diameter have impacted the Earth on average once every 500,000 years. Larger asteroids are less common. Small near-Earth asteroids are regularly observed.

text: The S-type asteroid is a member of the Flora family, one of the largest groups of stony asteroids in the main-belt. It orbits the Sun at a distance of 1.8–2.7 AU once every 3 years and 4 months (1,226 days). Its orbit is tilted by 5 degrees to the plane of the ecliptic and shows a notable eccentricity of 0.20. The body rotates around its axis once every 10.4 hours and has an albedo of 0.18 and 0.36, according to two different observations made by the Wide-field Infrared Survey Explorer. The Collaborative Asteroid Lightcurve Link assumes an intermediate albedo of 0.24, a figure more in line with those typically found for Flora asteroids.

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: 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.

E-type asteroids, an example of this type, are uncommon in the main belt  but become more common toward the inner belt and would be expected to be most common in E-belt.  The Hungaria asteroids, which are a remnant of the E-belt in this model, contain a sizable fraction of E-type asteroids.

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: 1566 Icarus ( ) is an Apollo asteroid (a subclass of near-Earth asteroid) that at perihelion comes closer to the Sun than Mercury, i.e. it is a Mercury-crossing asteroid. It is also a Venus and Mars-crosser. It is named after Icarus of Greek mythology, who flew too close to the Sun. It was discovered on 27 June 1949 by Walter Baade at Palomar Observatory. From 1949 until the discovery of 3200 Phaethon in 1983, it was known as the asteroid that passed closest to the Sun.

text: C-type asteroids are carbonaceous asteroids. They are the most common variety, forming around 75% of known asteroids.  They are distinguished by a very low albedo because their composition includes a large amount of carbon, in addition to rocks and minerals.  They occur most frequently at the outer edge of the asteroid belt, 3.5 astronomical units (AU) from the Sun, where 80% of the asteroids are of this type, whereas only 40% of asteroids at 2 AU from the Sun are C-type.  The proportion of C-types may actually be greater than this, because C-types are much darker than most other asteroid types except D-types and others common only at the extreme outer edge of the asteroid belt.

text: Composition is calculated from three primary sources: albedo, surface spectrum, and density. The last can only be determined accurately by observing the orbits of moons the asteroid might have. So far, every asteroid with moons has turned out to be a rubble pile, a loose conglomeration of rock and metal that may be half empty space by volume. The investigated asteroids are as large as 280 km in diameter, and include 121 Hermione (268×186×183 km), and 87 Sylvia (384×262×232 km). Only half a dozen asteroids are larger than 87 Sylvia, though none of them have moons; however, some smaller asteroids are thought to be more massive, suggesting they may not have been disrupted, and indeed 511 Davida, the same size as Sylvia to within measurement error, is estimated to be two and a half times as massive, though this is highly uncertain. The fact that such large asteroids as Sylvia can be rubble piles, presumably due to disruptive impacts, has important consequences for the formation of the Solar System: Computer simulations of collisions involving solid bodies show them destroying each other as often as merging, but colliding rubble piles are more likely to merge. This means that the cores of the planets could have formed relatively quickly.

text: Once Brooke convinces the Geotopians that preventing the asteroid's fall is more important than their lost youth, they and the herd help with Buck's plan, which is to fill up a geyser with the crystals so that the pressure launches them into space to draw the asteroid away. The dromaeosaurs attempt to intervene, but Buck convinces Roger that they will not be able to survive the asteroid, and he in turn convinces Gavin and Gertie to help. The plan works, and the asteroid is pulled back into space. The herd then departs back home, including Sid, who parts ways from Brooke, but just after they leave, an asteroid piece falls inside a hot spring, giving it rejuvenating properties and making the Geotopians and Sid's grandmother, who stayed behind with them, regain their youth. After the herd returns, Manny reconciles with Julian, Peaches and Julian celebrate their wedding, Diego and Shira become heroes to the kids who were scared of them before, and a rejuvenated Brooke appears during the ceremony to reunite with Sid.

text: There are only 14 known Amor asteroids whose average distance from the Sun is beyond the asteroid belt. Their semi-major axes are greater than 3.57 AU and they are called Amor IV asteroids. All are Jupiter crossers. Though they have very high eccentricities (0.65 to 0.75), their orbits are not as eccentric as those of most Damocloids and comets, which tend to have eccentricities around 0.9. The only named Amor IV asteroid is 3552 Don Quixote and the only other numbered Amor IV asteroid is . So far, no Amor asteroid has been discovered that crosses the orbit of Saturn.

text: The commercial competition was won by a design called 'Foresight' created by SpaceWorks Enterprises, Inc. SpaceWorks proposed a simple orbiter with only two instruments and a radio beacon at a cost of ~140 million USD, launched aboard a Minotaur IV between 2012 and 2014, to arrive at Apophis five to ten months later. It would then rendezvous with, observe, and track the asteroid. Foresight would orbit the asteroid to gather data with a multi-spectral imager for one month. It would then leave orbit and fly in formation with Apophis around the Sun at a range of two kilometres (1.2 miles). The spacecraft would use laser ranging to the asteroid and radio tracking from Earth for ten months to accurately determine the asteroid's orbit and how it might change.

text: Observations show that asteroids larger than 125 km in diameter have rotation rates that follow a Maxwellian frequency distribution, while smaller asteroids (in the 50 to 125 km size range) show a small excess of fast rotators. The smallest asteroids (size less than 50 km) show a clear excess of very fast and slow rotators, and this becomes even more pronounced as smaller populations are measured. These results suggest that one or more size-dependent mechanisms are depopulating the centre of the spin rate distribution in favour of the extremes. The YORP effect is a prime candidate. It is not capable of significantly modifying the spin rates of large asteroids by itself, so a different explanation must be sought for objects such as 253 Mathilde.

These results suggest that one or more size-dependent mechanisms are depopulating the centre of the spin rate distribution in favour of the extremes. The YORP effect is a prime candidate. It is not capable of significantly modifying the spin rates of large asteroids by itself, so a different explanation must be sought for objects such as

text: In 1981, a proposal for an asteroid mission was submitted to the European Space Agency (ESA). Named the Asteroidal Gravity Optical and Radar Analysis (AGORA), this spacecraft was to launch some time in 1990–1994 and perform two flybys of large asteroids. The preferred target for this mission was Vesta. AGORA would reach the asteroid belt either by a gravitational slingshot trajectory past Mars or by means of a small ion engine. However, the proposal was refused by the ESA. A joint NASA–ESA asteroid mission was then drawn up for a Multiple Asteroid Orbiter with Solar Electric Propulsion (MAOSEP), with one of the mission profiles including an orbit of Vesta. NASA indicated they were not interested in an asteroid mission. Instead, the ESA set up a technological study of a spacecraft with an ion drive. Other missions to the asteroid belt were proposed in the 1980s by France, Germany, Italy and the United States, but none were approved. Exploration of Vesta by fly-by and impacting penetrator was the second main target of the first plan of the multi-aimed Soviet Vesta mission, developed in cooperation with European countries for realisation in 1991–1994 but canceled due to the Soviet Union disbanding.

text: An early system of asteroid taxonomy was established in 1975 from the doctoral thesis work of David J. Tholen. This was based upon observations of a group of 110 asteroids. The U-type classification was used as a miscellaneous class for asteroids with unusual spectra that didn't fit into the C and S-type asteroid classifications. In 1976, some of these U-type asteroids with unusual moderate albedo levels were labeled as M-type.

text: Spacecraft visits to minor planets have mostly been flybys, and have ranged from dedicated missions to incidental flybys and targets of opportunity for spacecraft that have already completed their missions. The first spacecraft to visit an asteroid was Galileo, which flew past 951 Gaspra in October 1991; an incidental encounter while the probe was en route to Jupiter. The first dedicated mission was NEAR Shoemaker, which was launched in February 1996, and entered orbit around 433 Eros in February 2000, having first flown past 253 Mathilde. NEAR was also the first spacecraft to land on an asteroid, surviving what was intended to be an impact with Eros at 20:01 on 12 February 2001 at the planned end of its mission. As a result of its unexpected survival, the spacecraft's mission was extended until 1 March to allow data to be collected from the surface.

text: The combination of this fine asteroid dust, as well as ejected cometary material, produces the zodiacal light. This faint auroral glow can be viewed at night extending from the direction of the Sun along the plane of the ecliptic. Asteroid particles that produce the visible zodiacal light average about 40 μm in radius. The typical lifetimes of main-belt zodiacal cloud particles are about 700,000 years. Thus, to maintain the bands of dust, new particles must be steadily produced within the asteroid belt. It was once thought that collisions of asteroids form a major component of the zodiacal light.  However, computer simulations by Nesvorný and colleagues attributed 85 percent of the zodiacal-light dust to fragmentations of Jupiter-family comets, rather than to comets and collisions between asteroids in the asteroid belt. At most 10 percent of the dust is attributed to the asteroid belt.

text: An asteroid with an Earth-crossing orbit is not necessarily in danger of colliding with Earth. The orbit of an Earth-crossing asteroid may not even intersect with that of Earth. This apparent contradiction arises because many asteroids have highly inclined orbits, so although they may have a perihelion less than that of Earth, their paths can never cross. An asteroid for which there is some possibility of a collision with Earth at a future date and which is above a certain size is classified as a potentially hazardous asteroid (PHA). Specifically, an asteroid is a PHA if its Earth minimum orbital intersection distance (MOID) is <0.05 AU and its absolute magnitude is 22 or less. The concept of PHA is intended to replace the now abandoned strict definition of ECA (Earth-crossing asteroid) which existed for a few years. Determining if an asteroid was an ECA required calculation of its orbits millennia into the future, including planetary gravitational perturbations, to assess whether a collision with Earth was possible and this has proved to be impractical.

text: For example, there are very few asteroids with semimajor axis near 2.50 AU, period 3.95 years, which would make three orbits for each orbit of Jupiter (hence, called the 3:1 orbital resonance). Other orbital resonances correspond to orbital periods whose lengths are simple fractions of Jupiter's. The weaker resonances lead only to a depletion of asteroids, while spikes in the histogram are often due to the presence of a prominent asteroid family (see List of asteroid families).

text: Perhaps the most visually striking and scientifically compelling application of ISAR is in the deep space imaging of asteroids. A particularly beautiful example of this is the so-called "dog's bone" 216 Kleopatra asteroid, which lies roughly 20% further away from the earth than does the sun. The asteroid is only 60 miles wide at its midpoint. Yet the imagery is crisp and "feels" like an optical image. This has been cited as akin to using a Los Angeles telescope the size of the human eye's lens to image a car in New York. Of course the "trick" here is that the asteroid is presented amongst a very sparse background, allowing for substantial disambiguation.

text: asteroid, which lies roughly 20% further away from the earth than does the sun. The asteroid is only 60 miles wide at its midpoint. Yet the imagery is crisp and "feels" like an optical image. This has been cited as akin to using a Los Angeles telescope the size of the human eye's lens to image a car in New York. Of course the "trick" here is that the asteroid is presented amongst a very sparse background, allowing for substantial disambiguation.

text: In October 2013, the UN committee approved several measures to deal with terrestrial asteroid impacts, including the creation of an International Asteroid Warning Network (IAWN) to act as a clearing house for shared information on dangerous asteroids and for any future terrestrial impact events that are identified. A UN Space Missions Planning Advisory Group will also coordinate joint studies of the technologies for deflection missions, and as well provide oversight of actual missions. This is due to deflection missions typically involving a progressive movement of an asteroid's predicted impact point across the surface of the Earth (and also across the territories of uninvolved countries) until the NEO has been deflected either ahead of, or behind the planet at the point their orbits intersect. Schweickart states that an initial framework of international cooperation at the UN is needed to guide the policy makers of its member nations on several important NEO-related aspects.

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: Asteroids can be classified into three major types according to their spectra.  The original categories were created by Clark R. Chapman, David Morrison, and Ben Zellner in 1975, and further expanded by David J. Tholen in 1984. In what is now known as the Tholen classification, the C-types are made of carbonaceous material, S-types consist mainly of silicates, and X-types are 'metallic'.  There are other classifications for unusual asteroids.  C- and S-type asteroids are the most common asteroids. In 2002 the Tholen classification was further "evolved" into the SMASS classification, expanding the number of categories from 14 to 26 to account for more precise spectroscopic analysis of the asteroids.

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: ESA had originally identified two NEOs as possible targets for its Quijote mission:  and (10302) 1989 ML. Neither asteroid represents a threat to Earth. In a subsequent study, two different possibilities were selected: the Amor asteroid 2003 SM84 and 99942 Apophis; the latter is of particular significance to Earth as it will make a close approach in 2029 and 2036. In 2005, ESA announced at the 44th annual Lunar and Planetary Science Conference that its mission would be combined into a joint ESA-NASA Asteroid Impact & Deflection Assessment (AIDA) mission, proposed for 2019–2022.

text: A contact binary is a small Solar System body that is composed of two bodies that have gravitated toward each other until they touch. This means contact binaries have odd shapes. Comet Churyumov–Gerasimenko and Comet Tuttle are most likely contact binaries. Asteroids suspected of being contact binaries include the unusually elongated 624 Hektor and the bilobated 216 Kleopatra and 4769 Castalia. 25143 Itokawa, which was photographed by the Hayabusa probe, also appears to be a contact binary which has resulted in an elongated, bent body. About 10–15% of near-Earth asteroids larger than 200 meters are expected to be contact binaries with two lobes in mutual contact.

The first four gained popularity as full-fledged planets, but the rapid development of  telescopes led to new asteroids being frequently discovered in what is now known as the main-belt. Some astronomers grouped the first 10 asteroids alongside the first four asteroids as planets until the reclassification that was decided upon after the discovery of Hygiea, the 10th known asteroid.

text: According to Ouyang Ziyuan's report to the 16th Conference of the Chinese Academy of Sciences, Chang'e 2 departed from L2 on 15 April 2012, and began a mission to the asteroid 4179 Toutatis. The flyby was successfully achieved on 13 December 2012 at 16:30:09 Beijing Time (08:30:09 GMT). Close-up images of the asteroid, with a resolution of up to  per pixel, were later published online. The flyby was the first time an unmanned spacecraft had imaged the asteroid so closely. Chang'e-2 came as close as  to Toutatis, and took pictures of the asteroid at a relative velocity of  per second. China thus became the fourth space agency to conduct a successful mission to an asteroid, after NASA, Europe's ESA and Japan's JAXA.

text: Given the size of the SL9 impactors, it is likely that this object was less than one kilometer in diameter.Finding water at the site would indicate that the impactor was a comet, as opposed to an asteroid or a very small, icy moon. At first it was believed that the object was more likely to be a comet since comets generally have more planet crossing orbits. At the distance of Jupiter (5.2 AU) most small comets are not close enough to the Sun to be very active, and so would be hard to detect. Small kilometer-sized asteroids would also be hard to detect, however, and recent work by Orton et al. and Hammel et al. has strongly suggested the impactor was an asteroid, as it left only one impact site, did not reduce Jovian decametric radiation emission by contributing significant dust to the Jovian magnetosphere, and produced high altitude dusty debris full of silica, very different than what was produced by SL9.

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.

text: Deep Space Habitat (DSH) is a 2012 proposed NASA conceptual design to support a crew of 4 for exploration beyond Low Earth orbit. Initial concept missions include 60-day and 500-day mission configurations, composed of International Space Station-derived hardware, the Orion crew capsule and various support craft. The Habitat would be equipped with at least one International Docking System Standard (IDSS) docking system. Developing a Deep Space Habitat would allow a crew to live and work safely in space for up to one year on missions to explore cis-lunar space and some near-Earth asteroids. It would also provide experience favorable for designing longer-duration habitats that could be used for manned missions to Mars and more distant asteroids.

text: is an Aten-family asteroid, and as such is often near the glare of the Sun as the asteroid seldom travels outside Earth's orbit when the Earth is nearby. The orbit is poorly determined since the asteroid has an observation arc of only 9 days creating an orbital uncertainty of 7. Since the asteroid has not been observed since 14 March 2000, the uncertainty region has kept increasing. During the 2014 approach, 17 February 2014 was the first day that the nominal orbit had a solar elongation more than 90 degrees from the Sun making it easier to recover under a dark sky. Using the nominal orbit, the asteroid was expected to have an apparent magnitude of about 16 and pass  from Earth. Closest approach (perigee-geocentrical) was around 00:15 UTC on 18 February plus or minus about 13 hours. Even with an observation arc of 9 days, it was known that the minimum possible close approach distance to Earth on 18 February 2014 was  with a small chance that the asteroid would pass as far as  from Earth. Due to the uncertainty region of the asteroid, the asteroid could have been 75 degrees from the nominal position in the sky on 18 February 2014.

text: 259 Aletheia is a very large main-belt asteroid that was discovered by German–American astronomer Christian Peters on June 28, 1886, at Litchfield Observatory, Clinton, New York. The dark and heterogeneously composed X-type (Tholen: CP-type) asteroid contains primitive carbonaceous materials, responsible for its low albedo of 0.04. Aletheia measures about 185 kilometers in diameter and belongs to the largest asteroids of the main-belt. It has a semi-major axis of 3.1 AU and an orbit inclined by 11 degrees with a period of 5.55 years.

text: Asteroid mining has also been seriously considered. A NASA design study evaluated a 10,000 ton mining vehicle (to be assembled in orbit) that would return a 500,000 ton asteroid fragment to geostationary orbit. Only about 3,000 tons of the mining ship would be traditional aerospace-grade payload. The rest would be reaction mass for the mass-driver engine, which could be arranged to be the spent rocket stages used to launch the payload. Assuming that 100% of the returned asteroid was useful, and that the asteroid miner itself couldn't be reused, that represents nearly a 95% reduction in launch costs. However, the true merits of such a method would depend on a thorough mineral survey of the candidate asteroids; thus far, we have only estimates of their composition. One proposal is to capture the asteroid Apophis into earth orbit and convert it into 150 solar power satellites of 5 GW each or the larger asteroid 1999 AN10  which is 50x the size of  Apophis and large enough to build 7,500 5-Gigawatt Solar Power Satellites

text: A rotational light-curve of this asteroid was obtained from photometric observations made at the U.S. Palomar Transient Factory in October 2013. The light-curve gave a rotation period of  hours with a brightness variation of 0.11 in magnitude (U=2). According to the survey carried out by the NEOWISE mission of NASA's space-based Wide-field Infrared Survey Explorer, the asteroid measures 12.1 kilometers in diameter and its surface has an albedo of 0.084, while the Collaborative Asteroid Lightcurve Link assumes a standard albedo for carbonaceous asteroids of 0.057 and calculates a diameter of 11.3 kilometers, based on an absolute magnitude of 13.46.

text: 1333 Cevenola, provisional designation 1934 DA, is a stony, binary asteroid from the asteroid belt about 15 kilometers in diameter. It was discovered on 20 February 1934, by French female astronomer Odette Bancilhon at Algiers Observatory, Algeria in Northern Africa. The S-type asteroid is a member of the Eunomia family. More specifically, it is estimated to have a Sq spectral type, which would also agree with its family classification. It orbits the Sun at a distance of 2.3–3.0 AU once every four and a half years (1,561 days). Cevenolas orbit is mildly eccentric (0.13) and tilted by 15 degrees to the ecliptic.

He adopts the name 'Derec' from the name on his space suit, which he later finds out is only the suit's manufacturer. He is soon rescued by a colony of robots who are mining the asteroid in search of something hidden there.  Their mission is surrounded in the utmost secrecy such that Derec is not told what they searching for nor allowed to communicate with the outside world. However, the robots send a message to their commander asking what to do and continue their work.

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 asteroid is classified as both, C-type and X-type on the Tholen scheme. It is a member of the Hungaria family, which form the innermost dense concentration of asteroids in the Solar System. The body orbits the Sun at a distance of 1.6–2.2 AU once every 2 years and 8 months (964 days). Its orbit is tilted by 25 degrees to the plane of the ecliptic and shows an eccentricity of 0.15. Contrary to the expected low albedo for dark, carbonaceous CX-type asteroids, the Collaborative Asteroid Lightcurve Link (CALL) assumes a high albedo of 0.40 for the body. This is rather typical for the descendants of the E-belt, a hypothesized population of primordial asteroids, from which the E-type Hungarian asteroids with high inclinations and a semi-major axis of 1.9 AU are thought to have originated.

text: As of 2016, the asteroid's effective size, its composition and albedo, as well as its rotation period and shape remain unknown. Based on an absolute magnitude of 15.1, it measures between 3 and 6 kilometers in diameter, assuming an albedo in the range of 0.05 to 0.25. Since near-Earth asteroids are often of a silicaceous rather than of a carbonaceous composition, with higher albedos, typically above 0.20, the asteroid's diameter might be on the lower end of NASA's published conversion table, as the higher the body's reflectivity (albedo), the smaller its diameter, at a constant absolute magnitude (brightness).

text: 90 Antiope ( ) is a double asteroid in the outer asteroid belt. It was discovered on October 1, 1866, by Robert Luther. In 2000, it was found to consist of two almost-equally-sized bodies orbiting each other. At average diameters of about 88 km and 84 km, both components are among the 500 largest asteroids. Antiope is a member of the Themis family of asteroids that share similar orbital elements.

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: One more alternative to explosive deflection is to move the asteroid slowly over a time. Tiny constant thrust accumulates to deviate an object sufficiently from its predicted course. Edward T. Lu and Stanley G. Love have proposed using a large heavy unmanned spacecraft hovering over an asteroid to gravitationally pull the latter into a non-threatening orbit. The spacecraft and the asteroid mutually attract one another. If the spacecraft counters the force towards the asteroid by, e.g., an ion thruster, the net effect is that the asteroid is accelerated towards the spacecraft and thus slightly deflected from its orbit. While slow, this method has the advantage of working irrespective of the asteroid composition or spin rate – rubble pile asteroids would be difficult to deflect by means of nuclear detonations while a pushing device would be hard or inefficient to mount on a fast rotating asteroid. A gravity tractor would likely have to spend several years beside the asteroid to be effective.

text: According to the space-based surveys carried out by the Japanese Akari satellite and the NEOWISE mission of NASA's Wide-field Infrared Survey Explorer, the asteroid measures 15.7 and 14.2 kilometers in diameter, respectively. Conversely, the Collaborative Asteroid Lightcurve Link calculates a diameter of only 7.5 kilometers, due to an assumed albedo of 0.20, which is untypically high for a carbonaceous asteroid.

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: Baetslé takes 6.08 hours for a full a rotation around its axis. Two observations by the Infrared Astronomical Satellite, IRAS, showed an absolute magnitude of 13.40 and a low geometric albedo of 0.03. While the size, rotational period and orbital data are commonly found among main-belt asteroids, the albedo was exceptionally low and suggested that the body's composition could be mostly carbonaceous. However, subsequent observations by the Wide-field Infrared Survey Explorer's NEOWISE mission gave a higher albedo of 0.22 and 0.30 and the Collaborative Asteroid Lightcurve Link derives a value of 0.33, assuming the body to be of a stony rather than of a carbonaceous composition. This also concurs with the fact that, based on its orbital elements, the asteroid is a member of the Flora family, one of the largest groups of rather bright and stony asteroids in the main-belt.

text: The Planet V hypothesis posits that a fifth terrestrial planet created the Late Heavy Bombardment when its meta-stable orbit entered the inner asteroid belt. The hypothetical fifth terrestrial planet, Planet V, had a mass less than half of Mars and originally orbited between Mars and the asteroid belt. Planet V's orbit became unstable due to perturbations from the other inner planets causing it to intersect the inner asteroid belt. After close encounters with Planet V, many asteroids entered Earth-crossing orbits producing the Late Heavy Bombardment. Planet V was ultimately lost, likely plunging into the Sun. In numerical simulations, an uneven distribution of asteroids, with the asteroids heavily concentrated toward the inner asteroid belt, has been shown to be necessary to produce the LHB via this mechanism. An alternate version of this hypothesis in which the lunar impactors are debris resulting from Planet V impacting Mars, forming the Borealis Basin, has been proposed to explain a low number of giant lunar basins relative to craters and a lack of evidence of cometary impactors.

text: On 9 May 2003, Hayabusa (meaning, Peregrine falcon), was launched from an M-V rocket.  The goal of the mission was to collect samples from a small near-Earth asteroid named 25143 Itokawa. The craft rendezvoused with the asteroid in September 2005. It was confirmed that the spacecraft successfully landed on the asteroid in November 2005, after some initial confusion regarding the incoming data. Hayabusa returned to Earth with samples from the asteroid on 13 June 2010.

text: The Near Earth Asteroid Prospector, or NEAP, was a concept for a small innovative commercial spacecraft mission by the private company SpaceDev. The goal was to fly NEAP to a targeted near-Earth asteroid residing beyond Earth's orbit, successfully land one or more scientific instruments on the asteroid, communicate the scientific data to Earth, and claim the asteroid as private property. The project ran into fundraising difficulties. One of the most likely candidates was 4660 Nereus.

text: In 1998, the United States Congress mandated the Spaceguard Survey – detection of 90% of near-earth asteroids over 1 km diameter (that threaten global devastation) by 2008. Several surveys have undertaken "Spaceguard" activities (an umbrella term), including Lincoln Near-Earth Asteroid Research (LINEAR), Spacewatch, Near-Earth Asteroid Tracking (NEAT), Lowell Observatory Near-Earth-Object Search (LONEOS), Catalina Sky Survey (CSS), Campo Imperatore Near-Earth Object Survey (CINEOS), Japanese Spaceguard Association, Asiago-DLR Asteroid Survey (ADAS) and Near-Earth Object WISE (NEOWISE). In 2011, it was estimated that 93% of near-Earth asteroids larger than 1 km in diameter have been found, thus the original Spaceguard goal has been met. In 2005, in the USA, the original Spaceguard mandate was extended by the George E. Brown, Jr. Near-Earth Object Survey Act, which calls for NASA to detect 90% of NEOs with diameters of 140 meters or greater, by 2020.

text: Jupiter-family comets and long-period comets appear to follow very different fading laws. The JFCs are active over a lifetime of about 10,000 years or ~1,000 orbits whereas long-period comets fade much faster. Only 10% of the long-period comets survive more than 50 passages to small perihelion and only 1% of them survive more than 2,000 passages. Eventually most of the volatile material contained in a comet nucleus evaporates, and the comet becomes a small, dark, inert lump of rock or rubble that can resemble an asteroid. Some asteroids in elliptical orbits are now identified as extinct comets. Roughly six percent of the near-Earth asteroids are thought to be extinct comet nuclei.

text: A gravitational keyhole is a tiny region of space where a planet's gravity would alter the orbit of a passing asteroid such that the asteroid would collide with that planet on a given future orbital pass. The word "keyhole" contrasts the large uncertainty of trajectory calculations (between the time of the observations of the asteroid and the first encounter with the planet) with the relatively narrow bundle(s) of critical trajectories. The term was coined by P. W. Chodas in 1999. It gained some public interest when it became clear, in January 2005, that the Asteroid (99942) Apophis would miss the Earth in 2029 but may go through one or another keyhole leading to impacts in 2036 or 2037. Further research has since been done, however, which revealed the probability of the asteroid passing through the keyhole was extremely insignificant.

text: As their orbits evolved many of the E-belt asteroids would have acquired orbits similar to those of the Hungaria asteroids with high inclinations and semimajor axis between 1.8 and 2.0 AU.  Because orbits in this region are dynamically sticky these objects would form a quasi-stable reservoir.  As this population of the E-belt asteroids leaked from this reservoir they would produce a long-lived tail of impacts after the traditional end of the late heavy bombardment at 3.7 billion years ago.  A remnant representing roughly 0.1 – 0.4% of the original E-belt asteroids would remain as the current Hungaria asteroids.

text: Arthur C. Clarke coined the term in his novel Rendezvous with Rama (1972) where SPACEGUARD was the name of an early warning system created following a catastrophic asteroid impact. This name was later adopted by a number of real life efforts to discover and study near-Earth objects.A 1992 US Congressional study produced a "Spaceguard Survey Report" which led to a mandate that NASA locate 90% of near-Earth asteroids larger than 1 km within 10 years.  This is often referred to as the "Spaceguard Goal."  A number of efforts which receive money through NASA are all considered to be working on the "Spaceguard Project."

text: In 1975, an asteroid taxonomic system based on color, albedo, and spectral shape was developed by Clark R. Chapman, David Morrison, and Ben Zellner. These properties are thought to correspond to the composition of the asteroid's surface material. The original classification system had three categories: C-types for dark carbonaceous objects (75% of known asteroids), S-types for stony (silicaceous) objects (17% of known asteroids) and U for those that did not fit into either C or S. This classification has since been expanded to include many other asteroid types. The number of types continues to grow as more asteroids are studied.

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: There is increasing interest in identifying asteroids whose orbits cross Earth's, and that could, given enough time, collide with Earth (see Earth-crosser asteroids). The three most important groups of near-Earth asteroids are the Apollos, Amors, and Atens. Various asteroid deflection strategies have been proposed, as early as the 1960s.

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.

It was discovered at the Purple Mountain Observatory, Nanking, on October 30, 1957. Named for the country in which it was discovered, its name and number were actually taken from another asteroid that was considered a lost asteroid at the time, but was eventually rediscovered and given the new designation 3789 Zhongguo (1928 UF).

text: Until the age of space travel, objects in the asteroid belt were merely pinpricks of light in even the largest telescopes and their shapes and terrain remained a mystery. The best modern ground-based telescopes and the Earth-orbiting Hubble Space Telescope can resolve a small amount of detail on the surfaces of the largest asteroids, but even these mostly remain little more than fuzzy blobs. Limited information about the shapes and compositions of asteroids can be inferred from their light curves (their variation in brightness as they rotate) and their spectral properties, and asteroid sizes can be estimated by timing the lengths of star occulations (when an asteroid passes directly in front of a star). Radar imaging can yield good information about asteroid shapes and orbital and rotational parameters, especially for near-Earth asteroids. In terms of delta-v and propellant requirements, NEOs are more easily accessible than the Moon.

text: 2014 RC is a small Apollo near-Earth asteroid that made a close approach to Earth of  (0.1 lunar distances) around 18:02 UTC on 7 September 2014. It is the fastest rotating asteroid so far discovered. The asteroid briefly brightened to about apparent magnitude 11.5, so it was not visible to the naked eye or common binoculars. At the peak brightness the asteroid had a declination of –47, and was most easily visible over New Zealand. The asteroid is approximately the diameter of the Chelyabinsk meteor, and passed almost as close to Earth as 367943 Duende (2012 DA14) did in 2013. During 2014, asteroids 2014 AA and  have come closer to Earth. 2014 RC was removed from the JPL Sentry Risk Table on 5 September 2014 and there are no known possible impact dates in the next 100 years. On 8 September 2115 the asteroid will pass about  from the moon. On 5 September 1973, the asteroid passed between  and  from Earth.

This will be the first spacecraft to target an asteroid known to have a moon (243 Ida was visited by the Galileo spacecraft but its moon was a surprise). The mission is intended to test whether a spacecraft could successfully deflect an asteroid on a collision course with Earth; it would study Didymos from orbit, while also crashing a smaller spacecraft into Didymoon, in order to study the effect on its orbit.

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: 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: The Apollo asteroids are a group of near-Earth asteroids named after 1862 Apollo, discovered by German astronomer Karl Reinmuth in the 1930s. They are Earth crossing asteroids that have an orbital semi-major axis greater than that of the Earth (> 1 AU) but perihelion distances less than the Earth's aphelion distance (q < 1.017 AU).

text: In September 2007, a report published in Nature proposed an origin for the asteroid that created the Chicxulub Crater. The authors, William F. Bottke, David Vokrouhlický, and David Nesvorný, argued that a collision in the asteroid belt 160 million years ago resulted in the Baptistina family of asteroids, the largest surviving member of which is 298 Baptistina. They proposed that the "Chicxulub asteroid" was also a member of this group. The connection between Chicxulub and Baptistina is supported by the large amount of carbonaceous material present in microscopic fragments of the impactor, suggesting the impactor was a member of a rare class of asteroids called carbonaceous chondrites, like Baptistina. According to Bottke, the Chicxulub impactor was a fragment of a much larger parent body about  across, with the other impacting body being around  in diameter. In 2011, new data from the Wide-field Infrared Survey Explorer revised the date of the collision which created the Baptistina family to about 80 million years ago. This makes an asteroid from this family highly improbable to be the asteroid that created the Chicxulub Crater, as typically the process of resonance and collision of an asteroid takes many tens of millions of years. In 2010, another hypothesis was offered which implicated the newly discovered asteroid P/2010 A2, a member of the Flora family of asteroids, as a possible remnant cohort of the K/Pg impactor.

text: The upper limit is also vague. Two orbiting bodies are sometimes described as a double body rather than primary and satellite. Asteroids such as 90 Antiope are considered double asteroids, but they have not forced a clear definition of what constitutes a moon. Some authors consider the Pluto–Charon system to be a double (dwarf) planet. The most common dividing line on what is considered a moon rests upon whether the barycentre is below the surface of the larger body, though this is somewhat arbitrary, because it depends on distance as well as relative mass.

text: This mission would place an asteroid in lunar orbit, rather than sending astronauts to an asteroid in deep space.The Keck Institute for Space Studies at the California Institute of Technology, in partnership with the Jet Propulsion Laboratory, estimates a mission cost of approximately $2.6 billion.  By contrast, original estimates for colonization of the Moon, as a part of the Constellation Program, reached a total cost of $150 billion.  However, the $2.6 billion estimate is solely the cost of asteroid capture.  It does not include any developmental costs, nor does it cover the costs of Orion flights to a 4 m asteroid once it is captured, so this comparison does not include the full costs of this enterprise.The Obama Administration estimates that this mission would actually cost even less than the estimated $2.6 billion and was a part of the FY2014 budget request.Steps toward accomplishing this mission would simultaneously develop advanced solar electric propulsion technology.

text: Near Earth Space Surveillance (NESS), led by Principal Investigator Alan Hildebrand of the University of Calgary, will use NEOSSat to search for and track near-Earth asteroids inside Earth's orbit around the Sun, including asteroids in the Aten and Atira classes. These asteroids are particularly difficult to detect from the surface of the Earth, as they are usually positioned in the daylit or twilit sky, when background light from the Sun makes such faint objects invisible. This form of stray light is not an issue for a telescope in orbit, making even a small-aperture telescope such as that on NEOSSat capable of detecting faint asteroids. The NESS science team expects to be able to detect many such asteroids as faint as visual magnitude 19. The NESS mission is funded by the CSA.

text: Other situations, however, may have more direct financial application, such as an asteroid defense mechanism.  There is a minute probability of an asteroid strike large enough to destroy the planet - what should we do about this?  Clearly if we poured the entire GDP of the planet into protecting against this, we could minimize the risk, but might there be better things to spend it on?  Instead, armed with a value for the planet, we can put in place systems that provide early warning and a good measure of the probability of asteroid impact.  This knowledge itself reduces the average cost of a meteor impact to an "acceptable" level.

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.

text: Sisyphus will pass  from Earth on 24 November 2071, and will peak at roughly apparent magnitude 9.3 on November 26, 2071. When it was discovered it peaked at magnitude 9.0 on 25 November 1972. It is one of the brightest near-Earth asteroids. With a measured mean diameter in the range of 5.7–8.9 kilometers, it the largest of the Earth-crossing asteroids, comparable in size to the Chicxulub object whose impact contributed to the extinction of the dinosaurs. Larger near-Earth asteroids which are neither classified as Apollos nor Earth-crossers include 1036 Ganymed (32 km), 3552 Don Quixote (19 km), 433 Eros (17 km), and 4954 Eric (10.8 km).

text: Located in the outermost part of the main-belt, the asteroid is a member of the Hilda family, a large group of asteroids that are thought to have originated from the Kuiper belt. They orbit in a 3:2 orbital resonance with the gas giant Jupiter, meaning that for every 2 orbits Jupiter completes around the Sun, a Hildian asteroid will complete 3 orbits. The asteroid's orbit does not cross the path of any of the planets and therefore it will not be pulled out of orbit by Jupiter's gravitational field. As a result of this, it is likely that the asteroid will remain in a stable orbit for thousands of years.

These include Aten asteroids (including Apohele asteroids and the hypothetical Vulcanoid asteroids) and some Apollo asteroids (perhaps including quasi-satellites of Earth). Unfortunately, observations of such transits are difficult because all of these asteroids are only a few kilometres in diameter at most, so that their angular diameter is too tiny to observe against the Sun.

text: The Asteroid Impact and Deflection Assessment (AIDA) mission is a proposed space probe which would study and demonstrate the kinetic effects of crashing an impactor spacecraft into an asteroid moon. The mission is intended to test whether a spacecraft could successfully deflect an asteroid on a collision course with Earth. It would be composed of two spacecraft: AIM, which would orbit the asteroid, and DART, which would impact its moon. Besides the observation of the change of orbital parameters of the asteroid moon, the observation of the plume, the crater, and the freshly exposed material will provide truly unique information for asteroid deflection, science and mining communities.

text: On 12 November, Hayabusa closed in to  from the asteroid's surface.  MINERVA was released but due to an error failed to reach the surface. On 19 November, Hayabusa landed on the asteroid. There was considerable confusion during and after the maneuver about precisely what had happened, because the high-gain antenna of the probe could not be used during final phase of touch-down, as well as the blackout during handover of ground station antenna from DSN to Usuda station.  It was initially reported that Hayabusa had stopped at approximately 10 meters from the surface, hovering for 30 minutes for unknown reasons. Ground control sent a command to abort and ascend, and by the time the communication was regained, the probe had moved 100 km away from the asteroid.  The probe had entered into a safe mode, slowly spinning to stabilize attitude control. However, after regaining control and communication with the probe, the data from the landing attempt were downloaded and analyzed, and on 23 November, JAXA announced that the probe had indeed landed on the asteroid's surface. Unfortunately, the sampling sequence was not triggered since a sensor detected an obstacle during descent; the probe tried to abort the landing, but since its altitude was not appropriate for ascent, it chose instead a safe descent mode. This mode did not permit a sample to be taken, but there is a high probability that some dust may have whirled up into the sampling horn when it touched the asteroid, so the sample canister currently attached to the sampling horn was sealed.  On November 25, a second touchdown attempt was performed. It was initially thought that this time, the sampling device was activated; however, later analysis decided that this was probably another failure and that no pellets were fired. Due to a leak in the thruster system, the probe was put in a "safe hold mode".

text: Because of the need to conserve fuel for possible encounters with Kuiper belt objects subsequent to the Pluto flyby, intentional encounters with objects in the asteroid belt were not planned. After launch, the New Horizons team scanned the spacecraft's trajectory to determine if any asteroids would, by chance, be close enough for observation. In May 2006 it was discovered that New Horizons would pass close to the tiny asteroid 132524 APL on June 13, 2006. Closest approach occurred at 4:05 UTC at a distance of . The asteroid was imaged by Ralph (use of LORRI was not possible because of proximity to Sun), which gave the team a chance to test Ralph capabilities, and make observations of the asteroid's composition as well as light and phase curves. The asteroid was estimated to be  in diameter. The spacecraft successfully tracked the asteroid over June 10–12, 2006. This allowed the mission team to test the spacecraft's ability to track rapidly moving objects. Images were obtained through the Ralph telescope.

text: The physical composition of asteroids is varied and in most cases poorly understood. Ceres appears to be composed of a rocky core covered by an icy mantle, where Vesta is thought to have a nickel-iron core, olivine mantle, and basaltic crust. 10 Hygiea, however, which appears to have a uniformly primitive composition of carbonaceous chondrite, is thought to be the largest undifferentiated asteroid. Most of the smaller asteroids are thought to be piles of rubble held together loosely by gravity, though the largest are probably solid. Some asteroids have moons or are co-orbiting binaries: Rubble piles, moons, binaries, and scattered asteroid families are thought to be the results of collisions that disrupted a parent asteroid.

text: Among the proposed experimental research missions discussed were the alteration of an asteroid's spin rate, as well as changing the orbit of one part of a binary asteroid pair. Following the seminar's round-table discussions the workshop generally agreed that the vehicle of choice (needed to deflect an asteroid) would be powered by a low-thrust ion plasma engine. Landing a nuclear-powered plasma engined pusher vehicle on the asteroid's surface was seen as promising, an early proposal that would later encounter a number of technical obstacles.  Nuclear explosives were seen as "too risky and unpredictable" for several reasons, warranting the view that gently altering an asteroid's trajectory was the safest approach—but also a method requiring years of advance warning to successfully accomplish.

text: In 1851, after the fifteenth asteroid (Eunomia) had been discovered, Johann Franz Encke made a major change in the upcoming 1854 edition of the Berliner Astronomisches Jahrbuch (BAJ, Berlin Astronomical Yearbook). He introduced a disk (circle), a traditional symbol for a star, as the generic symbol for an asteroid. The circle was then numbered in order of discovery to indicate a specific asteroid (although he assigned ① to the fifth, Astraea, while continuing to designate the first four only with their existing iconic symbols). The numbered-circle convention was quickly adopted by astronomers, and the next asteroid to be discovered (16 Psyche, in 1852) was the first to be designated in that way at the time of its discovery. However, Psyche was given an iconic symbol as well, as were a few other asteroids discovered over the next few years (see chart above). 20 Massalia was the first asteroid that was not assigned an iconic symbol, and no iconic symbols were created after the 1855 discovery of 37 Fides. That year Astraea's number was increased to ⑤, but the first four asteroids, Ceres to Vesta, were not listed by their numbers until the 1867 edition. The circle was soon abbreviated to a pair of parentheses, which were easier to typeset and sometimes omitted altogether over the next few decades, leading to the modern convention.

text: According to the survey carried out by the NEOWISE mission of NASA's space-based Wide-field Infrared Survey Explorer, the asteroid measures 7.2 kilometers in diameter and its surface has an albedo of 0.23. The Collaborative Asteroid Lightcurve Link assumes a standard albedo for carbonaceous C-type asteroids of 0.057, and calculates a diameter of 10.4 kilometers, as the lower the albedo, the larger a body's diameter, at a constant absolute magnitude. A large-scale survey by Pan-STARRS, however, classifies the body as a X-type asteroid, which metallic core group has an intermediate albedo between stony and carbonaceous bodies. In September 2010, a photometric light-curve analysis at the U.S. Palomar Transient Factory, California, gave a long rotation period of  hours with a brightness variation of 0.61 in magnitude (U=2). This makes it a relatively slow rotator for an asteroid of its size, which normally have periods of just a few hours rather than several days.

text: Neptune's orbit has a profound impact on the region directly beyond it, known as the Kuiper belt. The Kuiper belt is a ring of small icy worlds, similar to the asteroid belt but far larger, extending from Neptune's orbit at 30 AU out to about 55 AU from the Sun. Much in the same way that Jupiter's gravity dominates the asteroid belt, shaping its structure, so Neptune's gravity dominates the Kuiper belt. Over the age of the Solar System, certain regions of the Kuiper belt became destabilised by Neptune's gravity, creating gaps in the Kuiper belt's structure. The region between 40 and 42 AU is an example.

text: Like in the original Asteroids the objective is to score as many points as possible by destroying asteroids and flying saucers.  The asteroids come in three different sizes.  If the player fires at and hits a large asteroid, it breaks into medium size asteroids. If the player fires at and hits a medium asteroid, it breaks into small asteroids.  If a player fires at and hits a small asteroid, it disappears.  Different points are awarded for hitting each size of asteroid, and for hitting flying saucers. The player controls a ship that can rotate left and right, fire shots straight forward, and thrust forward. Asteroids Deluxe replaces the hyperspace feature with shields which deplete with use. Other differences include asteroids which rotate and a new enemy which is dubbed a "killer satellite" which would, when shot, break apart into three smaller ships that homed in on the player's position.  The screen of the game is wrapped both vertically and horizontally so that if any object moves past the top edge of the screen it reappears on the bottom edge at the same lateral location, and if it moves past the left side of the screen, it reappears on the right side of the screen in the same vertical location.  Topologically, the screen is a torus.

text: The asteroid is a member of the Eunomia family, a large group of S-type asteroids and the most prominent family in the intermediate main-belt. It orbits the Sun at a distance of 2.1–3.1 AU once every 4 years and 3 months (1,547 days). Its orbit shows an eccentricity of 0.20 and is tilted by 12 degrees to the plane of the ecliptic. It has a well-defined rotation period of 3.89 hours, measured by several photometric light-curve observations. Based on measurements by the Japanese Akari satellite and the Wide-field Infrared Survey Explorer, the body's albedo is inconclusive – ranging from 0.07 to 0.27 – while the Collaborative Asteroid Lightcurve Link (CALL) assumes an albedo of 0.21, typical for stony asteroids.

text: Ceres is the largest object in the asteroid belt.It is sometimes assumed that Ceres has been reclassified as a dwarf planet, and that it is therefore no longer considered an asteroid. For example, a news update at Space.com spoke of "Pallas, the largest asteroid, and Ceres, the dwarf planet formerly classified as an asteroid", whereas an IAU question-and-answer posting states, "Ceres is (or now we can say it was) the largest asteroid", though it then speaks of "other asteroids" crossing Ceres' path and otherwise implies that Ceres is still considered an asteroid. The Minor Planet Center notes that such bodies may have dual designations. The 2006 IAU decision that classified Ceres as a dwarf planet never addressed whether it is or is not an asteroid. Indeed, the IAU has never defined the word 'asteroid' at all, having preferred the term 'minor planet' until 2006, and preferring the terms 'small Solar System body' and 'dwarf planet' after 2006. Lang (2011) comments "the [IAU has] added a new designation to Ceres, classifying it as a dwarf planet. ... By [its] definition, Eris, Haumea, Makemake and Pluto, as well as the largest asteroid, 1 Ceres, are all dwarf planets", and describes it elsewhere as "the dwarf planet–asteroid 1 Ceres".

text: The original Nice model was not without its own problems, however. During Jupiter's and Saturn's divergent migration secular resonances sweep through the inner Solar System. As the ν secular resonance sweeps through the terrestrial planet region it excites eccentricities beyond their current values potentially destabilizing the inner Solar System. Jupiter's and Saturn's slow approach to the 2:1 resonance is particularly problematic as in numerical simulations Mars's orbit intersects those of the other planets resulting in collisions between planets or in Mars's ejection from the Solar System. The orbits of the asteroids are also significantly altered: the ν secular resonance excites inclinations and the ν secular resonance excites eccentricities removing low-inclination asteroids as they sweep across the asteroid belt. As a result, the surviving asteroid belt is left with a larger fraction of high inclination objects than is currently observed.

text: The asteroid belt occupies the orbit between Mars and Jupiter, between 2.3 and 3.3 AU from the Sun. It is thought to be remnants from the Solar System's formation that failed to coalesce because of the gravitational interference of Jupiter. The asteroid belt contains tens of thousands, possibly millions, of objects over one kilometre in diameter. Despite this, the total mass of the asteroid belt is unlikely to be more than a thousandth of that of Earth. The asteroid belt is very sparsely populated; spacecraft routinely pass through without incident.

text: Jeanne Cavelos theorized in The Science of Star Wars that the frequency of meteoroids bombarding Hoth indicated that the planet was relatively young since in older solar systems, the debris is more cleared out. Since Hoth has complex lifeforms, Cavolos said the planet's age may be older, in the range of several billion years. The author said Hoth could be similar to Earth in age but lack neighboring planets like Jupiter and Saturn to shelter it from meteoroid impacts. She also said with the asteroid belt depicted in the film as close to Hoth that the belt was a likely source for meteoroids. (The asteroid belt itself is unrealistically depicted as being closely clustered, which would normally mean that the asteroids would be reduced to sand-sized rubble over a long enough timespan.)

text: The Sentinel Mission program is the cornerstone of the B612 Foundation's current efforts, with its preliminary design and system architecture level reviews planned for 2014, and its critical design review to be conducted in 2015. The infrared telescope would be launched atop a SpaceX Falcon 9 rocket, to be placed into a Venus-trailing Heliocentric orbit around the Sun. Orbiting between the Sun and Earth, the Sun's rays would always be behind the telescope's lens and thus never inhibit the space observatory's ability to detect asteroids or other near-Earth objects (NEOs). From the vantage of its inner-solar system orbit around the Sun, Sentinel will be able to "pick up objects that are currently difficult, if not impossible, to see in advance from Earth", such as occurred with the Chelyabinsk meteor of 2013 that went undetected until its explosion over Chelyabinsk Oblast, Russia. With the Sentinel Mission providing an accurate dynamic catalog of asteroids and other NEOs made available to scientists worldwide from the International Astronomical Union's Minor Planet Center, the data collected will calculate the risk of impact events with our planet, allowing for asteroid deflection by the use of gravity tractors to divert their trajectories away from Earth.

text: The migrations of the giant planets have many impact throughout the Solar System. The planetesimals scattered inward by Neptune enter planet-crossing orbits, initiating the Late Heavy Bombardment. Some of these planetesimals are jump-captured as Jupiter trojans during encounters between Jupiter and the ejected ice giant as Jupiter's semi-major axis changes.Others are captured as irregular satellites of the giant planets via three-body interactions during encounters between the ejected ice giant and the other planets. These encounters can also disturb the orbits of the regular satellites and may be responsible for the inclination of Iapetus's orbit. Saturn's rotational axis is tilted when it slowly crosses a spin-orbit resonance with Neptune. While Neptune migrates outward several AU, the hot classical Kuiper disk is formed as some planetesimals scattered outward by Neptune are captured in resonances, undergo an exchange of eccentricity vs inclination via the Kozai mechanism, and are released onto higher perihelion, stable orbits. Planetesimals captured in Neptune's 2:1 resonance during this early migration are released when an encounter with the ice giant causes its semi-major axis to jump outward, leaving behind a group of low-inclination, low-eccentricity objects with semi-major axes near 44 AU.  As Neptune slowly approaches its current orbit objects are left in fossilized high-perihelion orbits in the scattered disk. In the inner Solar System, the rapid separation of the orbits of Jupiter and Saturn reduces the excitation of the eccentricities of the inner planets due to resonance sweeping. Modest changes in the asteroids orbits also occur, shifting the distribution of eccentricities from that of the Grand Tack model toward the current distribution. Asteroid collisional families can be dispersed as the ice giant crosses the asteroid belt, and planetesimals from the outer belt are embedded in the asteroid belt as P-  and D-type asteroids. When the planets reach their present position the innermost part of the asteroid belt is disrupted leading to an extended Late Heavy Bombardment of the inner planets by rocky objects.

answers: Sun

text: Opportunity orbits the Sun at a distance of 3.2–4.8 AU once every 7 years and 11 months (2,880 days). Its orbit has an eccentricity of 0.20 and an inclination of 3° with respect to the ecliptic. Located in the outermost part of the main-belt, it is a member of the Hilda family, a large group of asteroids that are thought to have originated from the Kuiper belt. They orbit in a 3:2 orbital resonance with the gas giant Jupiter, meaning that for every 2 orbits Jupiter completes around the Sun, a Hildian asteroid will complete 3 orbits. The asteroid's orbit does not cross the path of any of the planets and therefore it will not be pulled out of orbit by Jupiter's gravitational field. As a result of this, it is likely that Opportunity will remain in a stable orbit for thousands of years. As no precoveries were taken, the asteroid's observation arc begins with its discovery observation in 1960.

text: Several theories have been posited to explain the formation of binary-asteroid systems. Many systems have significant macro-porosity (a "rubble-pile" interior). The satellites orbiting large main-belt asteroids such as 22 Kalliope, 45 Eugenia or 87 Sylvia may have formed by disruption of a parent body after impact or fission after an oblique impact. Trans-Neptunian binaries may have formed during the formation of the Solar System by mutual capture or three-body interaction. Near-Earth asteroids, which orbit in the inner part of the Solar System, most likely form by spin-up and mass shedding, likely as a result of the YORP effect. Numerical simulations confirm that when solar energy spins a “rubble pile” asteroid to a sufficiently fast rate by the YORP effect, material is thrown from the asteroid’s equator.  This process also exposes fresh material at the poles of the asteroid.

text: The primary goal of the mission was to study the near-Earth asteroid 433 Eros from orbit for approximately one year. Eros is an S-type asteroid approximately 13 × 13 × 33 km in size, the second largest near-Earth asteroid. Initially the orbit was circular with a radius of 200 km. The radius of the orbit was brought down in stages to a 50 × 50 km orbit on 30 April 2000 and decreased to 35 × 35 km on July 14, 2000. The orbit was raised over succeeding months to a 200 × 200 km orbit and then slowly decreased and altered to a 35 × 35 km retrograde orbit on December 13, 2000. The mission ended with a touchdown in the "saddle" region of Eros on February 12, 2001.

text: The diameter of most near-Earth asteroids that have not been studied by radar or infrared can generally only be estimated within about a factor of 2 based on the asteroid's absolute magnitude (H). Their mass, consequently, is uncertain by about a factor of 10. For near-Earth asteroids without a well-determined diameter, Sentry assumes a generic albedo of 0.15. More than two dozen known asteroids have higher than a one in a million chance of impacting into Earth within the next 100 years.

text: The diameter of most small asteroids is not directly measured and can only be estimated based on their brightness and distance. For this reason NASA and the Jet Propulsion Laboratory use the more practical measure of absolute magnitude (H). Any asteroid with an absolute magnitude of 22.0 or brighter is assumed to be of the required size, although only a coarse estimation of size can be found from the object's magnitude because an assumption must be made for its albedo which is also not usually known for certain. The NASA near-Earth object program uses an assumed albedo of 0.13 for this purpose.

text: It was discovered on 8 January 2011 by the Mt. Lemmon Survey at an apparent magnitude of 19.6 using a  reflecting telescope. Pan-STARRS precovery images from 8 November 2010 extended the observation arc to 317 days. Observations by the Gemini  telescope at Mauna Kea recovered the asteroid on October 20, 21 and 27, 2012, and extended the observation arc to 719 days. The October 2012 observations have reduced the orbit uncertainties by more than a factor of 60, meaning that the Earth's position in February 2040 no longer falls within the range of possible future paths for the asteroid. On 4 February 2040 the asteroid will pass no closer than  (~2.3 LD) from Earth. Until 21 December 2012 it was listed on the Sentry Risk Table with a rating on the Torino Scale of Level 1. A Torino rating of 1 is a routine discovery in which a pass near the Earth is predicted that poses no unusual level of danger. It is estimated that an impact would produce the equivalent of 100 megatons of TNT, roughly twice that of the most powerful nuclear weapon ever detonated (Tsar Bomba). This is powerful enough to damage a region at least a hundred miles wide.

text: The asteroid orbits the Sun at a distance of 2.2–3.0 AU once every 4 years and 2 months (1,532 days). Its orbit has an eccentricity of 0.15 and an inclination of 18° with respect to the ecliptic. Emilkowalski is the biggest member of a collisional group of asteroids, that resulted from the destruction of a larger parent body. The disruption happened approximately 220,000 years ago and it is one of the most recent asteroid breakups discovered in the main belt. The first unused observation at Palomar Observatory (DSS) dates back to 1953. The first used precovery was taken at Siding Spring Observatory in 1975, extending the asteroid's observation arc by 23 years prior to its discovery.

text: When first detected it was unknown what drove the ejecta plumes. Scheila's gravity is too large for electrostatics to launch dust. Cometary outgassing could not be ruled out until detailed spectroscopic observations indicated the absence of gas in Scheila's plumes. Observations by the Hubble Space Telescope and the Swift Gamma Ray Burst Mission's UV-optical telescope make it most likely that Scheila was impacted at ~5 km/s by a previously unknown asteroid ~35 meters in diameter.In 2010, the Hubble Space Telescope observed the aftermath of a catastrophic collision that destroyed the much smaller asteroid P/2010 A2. Each asteroid the size of Scheila might be hit by an impactor 10–100 meters in diameter approximately every 1000 years, so with 200 asteroids of this size or bigger in the asteroid belt, we can observe a collision as often as every 5 years.

Thus, in many stories and books the Asteroid Belt, if not a positive hazard, is still a rarely visited backwater in a colonized Solar System.

text: The asteroid belt is the circumstellar disc in the Solar System located roughly between the orbits of the planets Mars and Jupiter. It is occupied by numerous irregularly shaped bodies called asteroids or minor planets. The asteroid belt is also termed the main asteroid belt or main belt to distinguish it from other asteroid populations in the Solar System such as near-Earth asteroids and trojan asteroids. About half the mass of the belt is contained in the four largest asteroids: Ceres, Vesta, Pallas, and Hygiea. The total mass of the asteroid belt is approximately 4% that of the Moon, or 22% that of Pluto, and roughly twice that of Pluto's moon Charon (whose diameter is 1200 km).

text: Main-belt comets (MBCs) are bodies orbiting within the asteroid belt that have shown comet-like activity during part of their orbit. The Jet Propulsion Laboratory defines a main-belt asteroid as an asteroid with a semi-major axis (average distance from the Sun) of more than 2 AU but less than 3.2 AU, and a perihelion (closest approach distance to the Sun) of no less than 1.6 AU. David Jewitt from UCLA points out that these objects are most likely not comets with sublimating ice, but asteroids that exhibit dust activity, and hence he and others started calling these class of objects active asteroids.

text: Estimates of the total number of Jupiter trojans are based on deep surveys of limited areas of the sky. The  swarm is believed to hold between 160–240,000 asteroids with diameters larger than 2 km and about 600,000 with diameters larger than 1 km. If the  swarm contains a comparable number of objects, there are more than  Jupiter trojans 1 km in size or larger. For the objects brighter than absolute magnitude 9.0 the population is probably complete. These numbers are similar to that of comparable asteroids in the asteroid belt. The total mass of the Jupiter trojans is estimated at 0.0001 of the mass of Earth or one-fifth of the mass of the asteroid belt.

text: Magneto's first villainous act is attacking a United States military base called Cape Citadel after bringing down missiles. He is driven off by Charles Xavier's mutant students, the X-Men, in their first mission. He creates Asteroid M, an orbital base of operations in a hollowed out asteroid. He then gathers a group of angry and disillusioned mutants including his own, albeit at the time unbeknown to him, son and daughter Quicksilver and the Scarlet Witch and formed the Brotherhood of Evil Mutants to further his goals. Magneto briefly conquers the South American nation of San Marco in the hopes of establishing a mutant homeland there, but is again foiled by the X-Men. He tries to make the Toad infiltrate the X-Men. When that failed, he captures the Angel and tries to force him to tell the secrets of the X-Men. However, the other X-Men rescue their member and destroy Asteroid M.

It orbits among the Nysa asteroid family but its classification as an M-type asteroid does not match the more common F-type asteroid for this family, suggesting that it may be an interloper.  Spectroscopic analysis indicates the possible presence of hydrated silicates indicating that 135 Hertha should possibly be reclassified from its present M-type to the proposed W-type.

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 travelling 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). Asteroids in this context provide to space travel stories a space equivalent of reefs and underwater rocks in the older genre of seafaring adventures stories. And like reefs and rocks in the ocean, asteroids as navigation hazards can also be used by bold outlaws to avoid pursuit.

text: An outer Earth-grazer asteroid is an asteroid which is normally beyond Earth's orbit, but which can get closer to the Sun than Earth's aphelion (1.0167 AU), but not closer than Earth's perihelion (0.9833 AU). In other words, the asteroid's perihelion is between Earth's perihelion and aphelion. Outer Earth-grazer asteroids are split between Amor and Apollo asteroids, depending on the definition used.

text: Unlike comets, which spend most of their orbit at Jupiter-like or greater distances from the Sun, main-belt comets follow near-circular orbits within the asteroid belt that are undistinguishable from the orbits of many standard asteroids. Although quite a few short-period comets have semimajor axes well within Jupiter's orbit, main-belt comets differ in having small eccentricities and inclinations similar to main-belt asteroids. The first three identified main-belt comets all orbit within the outer part of the asteroid belt.

text: If such a crew is to be summoned to a distant asteroid, there may be less risky ways to divert the asteroid.  Another promising asteroid mitigation strategy is to land a crew on the asteroid well ahead of its impact date and to begin diverting some its mass into space to slowly alter its trajectory.  This is a form of rocket propulsion by virtue of Newton's third law with the asteroid's mass as the propellant.  Whether exploding nuclear weapons or diversion of mass is used, a sizable human crew may need to be sent into space for many months if not years to accomplish this mission.  Questions such as what the astronauts will live in and what the ship will be like are questions for the space architect.

text: The S-type asteroid – classified as a Sq-subtype in the SMASS taxonomy – orbits the Sun with a short orbital period at a distance of 0.3–1.2 AU once every 227 days. The body rotates every two and a half hours around its axis and has a notably high albedo of about 0.40. Its orbit is tilted by 29 degrees to the plane of the ecliptic. With an exceptionally high eccentricity of 0.59, it was the most eccentric Aten asteroid known at the time of discovery, more eccentric than previously discovered Aten, 3753 Cruithne. Since then, more eccentric Atens – such as (162004) 1991 VE, with an eccentricity of 0.665 – have been discovered. Due to this elongated orbit, the Aten asteroid and near-Earth asteroid also classifies as Earth-crosser, Venus-crosser and Mercury-grazer.

text: is an Apollo near-Earth asteroid discovered by the Catalina Sky Survey on April 5, 2010, four days before a close approach to Earth.  It is a relatively small space rock about  wide. With a 1-day observation arc, the asteroid had a 1 in 6 million chance of impacting in 2074. It was removed from the Sentry Risk Table on April 8, 2010. The asteroid passed Earth at a distance of about  at 02:07 UT on April 9, 2010 (7:06 pm EST on April 8).

text: The mass of all the objects of the asteroid belt, lying between the orbits of Mars and Jupiter, is estimated to be about 2.8–, or about 4% of the mass of the Moon. Of this, Ceres comprises , a third of the total. Adding in the next three most massive objects, Vesta (9%), Pallas (7%), and Hygiea (3%), brings this figure up to 51%; whereas the three after that, 511 Davida (1.2%), 704 Interamnia (1.0%), and 52 Europa (0.9%), only add another 3% to the total mass.

text: The asteroid belt is located between Mars and Jupiter. It is made of thousands of rocky planetesimals from  to a few meters across. These are thought to be debris of the formation of the Solar System that could not form a planet due to Jupiter's gravity. When asteroids collide they produce small fragments that occasionally fall on Earth. These rocks are called meteorites and provide information about the primordial solar nebula. Most of these fragments have the size of sand grains. They burn up in the Earth's atmosphere, causing them to glow like meteors.

text: One mystery of the asteroid belt is the relative rarity of V-type, or basaltic asteroids.  Theories of asteroid formation predict that objects the size of Vesta or larger should form crusts and mantles, which would be composed mainly of basaltic rock, resulting in more than half of all asteroids being composed either of basalt or olivine. Observations, however, suggest that 99 percent of the predicted basaltic material is missing.  Until 2001, most basaltic bodies discovered in the asteroid belt were believed to originate from the asteroid Vesta (hence their name V-type). However, the discovery of the asteroid 1459 Magnya revealed a slightly different chemical composition from the other basaltic asteroids discovered until then, suggesting a different origin. This hypothesis was reinforced by the further discovery in 2007 of two asteroids in the outer belt, 7472 Kumakiri and , with differing basaltic composition that could not have originated from Vesta. These latter two are the only V-type asteroids discovered in the outer belt to date.

text: 704 Interamnia is a very large asteroid, with an estimated diameter of 350 kilometres. Its mean distance from the Sun is 3.067 (AU). It was discovered on October 2, 1910 by Vincenzo Cerulli, and named after the Latin name for Teramo, Italy, where Cerulli worked. It is probably the fifth-most-massive asteroid after Ceres, Vesta, Pallas, and Hygiea, with a mass estimated to be 1.2% of the mass of the entire asteroid belt.

text: For the first 50 years of the program, students took photographic images of main-belt asteroids (between the orbits of Mars and Jupiter). Starting in 2009 students took digital images of (much fainter) near-Earth asteroids (inside the orbit of Mars). The process of orbit determination is conceptually the same in both cases. First students take a series of images of asteroids. After identifying the asteroid, its position on the image relative to known stars is carefully calculated. That relative position is then used to determine the position of the asteroid in celestial coordinates (right ascension and declination) at the exact time the image was taken. The series of positions as the asteroid moves across the sky allows the student to fit an approximate orbit to the asteroid. The measured asteroid coordinates (not the calculated orbital elements) are submitted to the Harvard-Smithsonian Center for Astrophysics.

text: The 2012 Desert RATS field tests did not involve either a desert, or a field; rather, they were conducted in JSC’s Building 9, the Space Vehicle Mockup Facility.  The tools and simulators were configured and optimized for a simulated mission to a near-Earth asteroid. A virtual reality lab provided an immersive environment for the extravehicular activity (EVA) crewmembers, integrating real-time graphics with crewmember motions and kinesthetic sensations of large objects – an asteroid in this case. The Active Response Gravity Offload System (ARGOS), a crane-based, reduced-gravity system, allowed crews to conduct EVAs in simulated microgravity.

text: Near-Earth objects are asteroids that are within the orbit of Mars. The delta-v to return from them are usually quite small, sometimes as low as 60 m/s, using aerobraking in Earth's atmosphere. However, heat shields are required for this, which add mass and constrain spacecraft geometry. The orbital phasing can be problematic; once rendezvous has been achieved, low delta-v return windows can be fairly far apart (more than a year, often many years), depending on the body.

text: Ceres, the asteroid belt's only dwarf planet, is about 950 km in diameter, whereas Vesta, Pallas, and Hygiea have mean diameters of less than 600 km. The remaining bodies range down to the size of a dust particle. The asteroid material is so thinly distributed that numerous unmanned spacecraft have traversed it without incident. Nonetheless, collisions between large asteroids do occur, and these can form an asteroid family whose members have similar orbital characteristics and compositions. Individual asteroids within the asteroid belt are categorized by their spectra, with most falling into three basic groups: carbonaceous (C-type), silicate (S-type), and metal-rich (M-type).

text: At ISDC-San Diego 2013, Kepler Energy and Space Engineering (KESE,llc) also announced it was going to mine asteroids, using a simpler, more straightforward approach: KESE plans to use almost exclusively existing guidance, navigation and anchoring technologies from mostly successful missions like the Rosetta/Philae, Dawn, and Hyabusa's Muses-C and current NASA Technology Transfer tooling to build and send a 4-module Automated Mining System (AMS) to a small asteroid with a simple digging tool to collect ~40 tons of asteroid regolith and bring each of the four return modules back to low Earth orbit (LEO) by the end of the decade. Small asteroids are expected to be loose piles of rubble, therefore providing for easy extraction.

text: In 1973 Asimov became a member of the Baker Street Irregulars (BSI), a fan club for Sherlock Holmes enthusiasts. A requirement for membership was that each new member should write and deliver a paper dealing with some question concerning any of the Sherlock Holmes stories, but this was waived in Asimov's case since he did not know the stories well enough. However, in 1975 the BSI decided to publish a collection of such articles, and members Banesh Hoffmann and Michael Harrison asked Asimov to write one. Hoffmann suggested that he write about The Dynamics of an Asteroid, a fictional treatise on astronomy written by Holmes's arch-enemy, Professor Moriarty. The Dynamics of an Asteroid is mentioned only once in Doyle's novel The Valley of Fear (1914), where it is described as a book renowned for containing such rarefied mathematics that there was supposedly no other scientist capable of fully understanding it. However, there were no other clues as to what its contents might be, since Doyle had written no more about it. Hoffmann therefore asked Asimov to speculate about what Moriarty might have written. This idea appealed to Asimov, and he wrote a 1,600-word essay on the matter, "Dynamics of an Asteroid," which was published in Beyond Baker Street: A Sherlockian Anthology (Bobbs-Merrill, 1976).

text: The S-type asteroid is a member of the Flora family, one of the largest groups of stony asteroids in the main-belt. It orbits the Sun at a distance of 1.9–2.7 AU once every 3 years and 5 months (1,258 days). Its orbit has an eccentricity of 0.17 and an inclination of 8° with respect to the ecliptic. The first precovery was taken at Palomar Observatory in 1954, extending the asteroid's observation arc by 38 years prior to its discovery.

text: 511 Davida is a large C-type asteroid in the asteroid belt. It was discovered by R. S. Dugan in 1903. It is one of the ten most-massive asteroids, and the 7th-largest asteroid. It is approximately 270–310 km in diameter and comprises an estimated 1.5% of the total mass of the asteroid belt. It is a C-type asteroid, which means that it is dark in colouring with a carbonaceous chondrite composition.

text: One useful mission for this near-term technology would be to deflect an asteroid that could collide with the Earth, depicted dramatically in the 1998 film Deep Impact. The extremely high performance would permit even a late launch to succeed, and the vehicle could effectively transfer a large amount of kinetic energy to the asteroid by simple impact, and in the event of an imminent asteroid impact a few predicted deaths from fallout would probably not be considered prohibitive. Also, an automated mission would eliminate the most problematic issues of the design: the shock absorbers.

text: On the next mission they are tasked to find a traitorous Confed colonel, named Gunther Ghent, who trained with Hawk's recon unit, only to find out he was selling weapons to the Red Hand. They then head back down to Caspian to take out a Super Mutant in one last encounter with the Mutants. They return to Osiris one last time to finally kill Shadoon, who is guarded by millions of Fire Hounds, Seers, and Psionic Artillery. They find out that a Commset has crashed on a planet called Singe. The Commset is being guarded by Fire Hounds, as well as Red Hand, who are working together to guard the Commset. They are then sent to Caspian to find a Synthetic traitor named Ty Mctavish, who is identical to Flint, the team has one last battle with Kingman's associates before heading out. They are sent to an asteroid named LB-429 where Mctavish was sending unknown data to an unknown contact on the planet, they investigate and find out the asteroid is infested by a race called the Shrikes. They find their leader, a Hunter Lord. The Shrikes are now invading Caspian, then later on, the team returns to Estuary one last time after so many missions not on Estuary. Now occupied by Shrikes, the team is now tasked to find some Alien Technology of unknown origin so the Confed can examine it. Then they return to LB-429 where they find the last of the Shrikes, and plan to finally destroy the Asteroid. They manage to kill the Hunter Lord and get evacuated, while several Confed jets destroy the asteroid. After the end, the team is seen walking into a dazing sunlight on an unknown planet (most likely Estuary), meaning they are finished with their jobs and are free to go.

text: Dating of howardite, eucrite and diogenite (HED) meteorites and H chondrite meteorites originating from the asteroid belt reveal numerous ages from 3.4–4.1 Ga and an earlier peak at 4.5 Ga. The 3.4–4.1 Ga ages has been interpreted as representing an increase in impact velocities as computer simulations using hydrocode reveal that the volume of impact melt increases 100–1000 times as the impact velocity increases from the current asteroid belt average of 5 km/s to 10 km/s. Impact velocities above 10 km/s require very high inclinations or the large eccentricities of asteroids on planet crossing orbits. Such objects are rare in the current asteroid belt but the population would be significantly increased by the sweeping of resonances due to giant planet migration.

text: (also written 2002 AA29) is a small near-Earth asteroid that was discovered on January 9, 2002 by the LINEAR (Lincoln Near Earth Asteroid Research) automatic sky survey. The diameter of the asteroid is only about . It revolves about the Sun on an almost circular orbit very similar to that of the Earth. This lies for the most part inside the Earth's orbit, which it crosses near the asteroid's furthest point from the Sun, the aphelion. Because of this orbit, the asteroid is classified as Aten type, named after the asteroid (2062) Aten.

text: An impact by a  asteroid on the Earth has historically caused an extinction-level event due to catastrophic damage to the biosphere. There is also the threat from comets coming into the inner Solar System. The impact speed of a long-period comet would likely be several times greater than that of a near-Earth asteroid, making its impact much more destructive; in addition, the warning time is unlikely to be more than a few months. Impacts from objects as small as  in diameter, which are far more common, are historically extremely destructive regionally (see Barringer crater).

text: The dark C-type asteroid orbits the Sun at a distance of 2.2–3.1 AU once every 4 years and 3 months (1,568 days). Although the asteroid is of carbonaceous rather than silicaceous composition, the Collaborative Asteroid Lightcurve Link classifies it as a member of the Eunomia family, a large group of otherwise S-type asteroids and the most prominent family in the intermediate main-belt. Its orbit is tilted by 14 degrees to the plane of the ecliptic and shows an eccentricity of 0.16. Several concurring photometric light-curve analysis rendered a well-defined rotation period of 9.6 hours. The body has an albedo between 0.04 and 0.05, according to the surveys carried out by the Infrared Astronomical Satellite IRAS, the Japanese Akari satellite, and the Wide-field Infrared Survey Explorer with its subsequent NEOWISE mission.

text: A small number of asteroids have been found which are co-orbital with Earth. The first of these to be discovered, asteroid 3753 Cruithne, orbits the Sun with a period slightly less than one Earth year, resulting in an orbit that (from the point of view of Earth) appears as a bean-shaped orbit centered on a position ahead of the position of Earth. This orbit slowly moves further ahead of Earth's orbital position. When Cruithne's orbit moves to a position where it trails Earth's position, rather than leading it, the gravitational effect of Earth increases the orbital period, and hence the orbit then begins to lag, returning to the original location. The full cycle from leading to trailing Earth takes 770 years, leading to a horseshoe-shaped movement with respect to Earth.

text: 5751 Zao has been observed by several groups to determine its rotational period.  Its light curve was observed by Pravec, et al. between 1992 and 1995 with the intention of determining its rotational period.  From its nearly constant brightness it was determined that the asteroid is roughly spherical and has a rotational period of ≥ 21.7 hr. Another group led by Wisniewski conducted an approximately 5 hour observation and were unable to conclude a rotational period.   5751 Zao was again observed in 2001 by Delbó, et al. using the Keck telescope.  They were able to determine the asteroid's albedo of 0.36 and re-classify the asteroid from X-type to E-type.  Using the asteroid's albedo and the Near Earth Asteroid Thermal Model (NEATM) the asteroid's diameter was estimated to be 2.3 km.  Further study of the asteroid by the Ondrejov Asteroid Photometry Project concludes that a rotational period of 76 hours is consistent with earlier measurements.

text: In general, the effect is size dependent, and will affect the semi-major axis of smaller asteroids, while leaving large asteroids practically unaffected. For kilometre-sized asteroids, the Yarkovsky effect is minuscule over short periods: the force on asteroid 6489 Golevka has been estimated at about 0.25 newton, for a net acceleration of 10 m/s². But it is steady; over millions of years an asteroid's orbit can be perturbed enough to transport it from the asteroid belt to the inner Solar System.

text: According to observations by NASA's space-based Wide-field Infrared Survey Explorer with its subsequent NEOWISE mission, the asteroid measures 3.4 kilometers in diameter, and its surface has an exceptionally high albedo of 0.40. However, the CALL assumes a much lower albedo of 0.06, a typical value for a carbonaceous asteroid, and calculates a diameter of 8.4 kilometers, as the lower the albedo (reflectivity) the larger the body's diameter at a constant absolute magnitude (brightness).

They are named after the main member, 434 Hungaria; the group contains at least 52 named asteroids. The Hungaria group is separated from the main body by the 4:1 Kirkwood gap and their orbits have a high inclination. Some members belong to the Mars-crossing category of asteroids, and gravitational perturbations by Mars are likely a factor in reducing the total population of this group.

text: These are objects in a near-Earth orbit without the tail or coma of a comet. , 15,342 near-Earth asteroids are known, ranging in size from 1 meter up to ~32 kilometers (1036 Ganymed). The estimated number of near-Earth asteroids over one kilometer in diameter was reduced from 1,000–2,000 to 500–1,000 in 2000. In 2011, the estimate of one-kilometre NEAs was narrowed to 981 ± 19 (of which over 90% have been discovered), while the number of NEAs larger than 140 metres across was estimated at 13,200 ± 1,900. There are about 1 million near-Earth asteroids about 40 meters in diameter—of which about 1 percent have been discovered. The composition of near-Earth asteroids is comparable to that of asteroids from the asteroid belt, reflecting a variety of asteroid spectral types.

Given the limited dispersion of the orbital parameters and the spectral homogeneity, it has been suggested that the group could be a remnant of the break-up of an asteroid from the  main asteroid belt. The radius of the parent asteroid was probably about 89 km, only slightly larger than that of Himalia, which retains approximately 87% of the mass of the original body. This indicates the asteroid was not heavily disturbed.

text: According to the survey carried out by NASA's Wide-field Infrared Survey Explorer with its subsequent NEOWISE mission, Arthurdent measures 3.5 kilometers in diameter and its surface has an albedo of 0.234. Inner main-belt asteroids with such an albedo are typically of a silicaceous rather than of a carbonaceous composition. Based on an absolute magnitude of 14.3 and a generic albedo in the range of 0.05 to 0.25, the asteroid measures between 3 and 8 kilometers in diameter. As of 2016, the asteroid's composition, rotation period and shape remain unknown.

text: Asteroid families are thought to have lifetimes of the order of a billion years, depending on various factors (e.g. smaller asteroids are lost faster). This is significantly shorter than the Solar System's age, so few if any are relics of the early Solar System. Decay of families occurs both because of slow dissipation of the orbits due to perturbations from Jupiter or other large bodies, and because of collisions between asteroids which grind them down to small bodies. Such small asteroids then become subject to perturbations such as the Yarkovsky effect that can push them towards orbital resonances with Jupiter over time. Once there, they are relatively rapidly ejected from the asteroid belt. Tentative age estimates have been obtained for some families, ranging from hundreds of millions of years to less than several million years as for the compact Karin family. Old families are thought to contain few small members, and this is the basis of the age determinations.

text: Most of the rocky impactors of the Late Heavy Bombardment originate from an inner extension of the asteroid belt yielding a smaller but longer lasting bombardment. The innermost region of the asteroid belt is currently sparsely populated due to the presence of the ν6 secular resonance. In the early Solar System, however, this resonance was located elsewhere and the asteroid belt extended farther inward, ending at Mars-crossing orbits. During the giant planet migration the ν6 secular resonance first rapidly traversed the asteroid belt removing roughly half of its mass, much less than in the original Nice model. When the planets reached their current positions the ν6 secular resonance destabilized the orbits of the innermost asteroids. Some of these quickly entered planet crossing orbit initiating the Late Heavy Bombardment. Others entered quasi-stable higher inclination orbits, later producing an extended tail of impacts, with a small remnant surviving as the Hungarias. The innermost (or E-belt) asteroids are estimated to have produced nine basin-forming impacts on the Moon between 4.1 and 3.7 billion years ago with three more originating from the core of the asteroid belt. The pre-Nectarian basins, part of the LHB in the original Nice model, are thought to be due to the impacts of leftover planetesimals from the inner Solar System. The increase in the orbital eccentricities and inclinations of the destabilized objects raised impact velocities, resulting in a change the size distribution of lunar craters, and in the production of impact melt in the asteroid belt.

text: A rotational light-curve was obtained from photometric observation made at the U.S. Palomar Transient Factory, California, in September 2013. It showed an above average rotation period of  hours with a brightness variation of 0.33 magnitude (U=2). The body's spectral type is unclear, as the Collaborative Asteroid Lightcurve Link (CALL) and Pan-STARRS large-scale survey classify it as a S-type and C-type asteroid, respectively. According to the survey carried out by NASA's space-based Wide-field Infrared Survey Explorer with its subsequent NEOWISE mission, the asteroid measures 4.2 kilometers in diameter and its surface has an albedo of 0.25, while CALL assumes a standard albedo for stony asteroids of 0.21 and calculates a diameter of 3.6 kilometers.

text: In 1973, Caltech astronomers Eleanor Helin and Gene Shoemaker began an observing program to search out and track previously unknown near-Earth asteroid, the Planet-Crossing Asteroid Survey (PCAS), a photographic plate survey that began on the Palomar 18" Schmidt telescope. Although primarily employed by the supernova survey to observe on the 48" Schmidt, Kowal provided "crucial observations" of particularly faint asteroids for the PCAS program with the larger telescope. His asteroid discoveries and co-discoveries include the notable asteroids Aten asteroid 2340 Hathor; the Apollo asteroids 1981 Midas, 2063 Bacchus, 2102 Tantalus and (5660) 1974 MA; the Amor asteroids (4596) 1981 QB and (4688) 1980 WF; and the Trojan asteroids 2241 Alcathous and 2594 Acamas. PCAS later moved to the 48" Schmidt, and ran in total for nearly 25 years, until June 1995.

text: A Hypervelocity Asteroid Intercept Vehicle (HAIV) is a spacecraft being developed by NASA to deflect dangerous Near Earth Objects (NEOs) such as comets and asteroids that threaten colliding with Earth. HAIVs focus on utilizing powerful explosives, such as nuclear bombs, to achieve deflection by detonating on the surface of the NEO to change its trajectory away from Earth. This method of  asteroid impact avoidance is intended to be used on dangerous NEOs detected within a short time frame (less than 5 years) before a possible impact event with Earth. The idea came about when asteroid detection became accurate and since then, scientists and engineers have come up with a well thought out design for an HAIV.

text: Asteroid capture happens when an asteroid "misses" the planet when it is falling towards it, but it is not fast enough to escape from the planet's orbit. In that case the asteroid is captured and reaches a stable (closed) elliptic orbit around the planet which does not intersect the planet's surface or atmosphere. This depends on variables such as the asteroid's velocity relative to the planet, the mass of the planet, and the trajectory of the asteroid.

text: 3753 Cruithne ( or ) is a Q-type, Aten asteroid in orbit around the Sun in 1:1 orbital resonance with Earth, making it a co-orbital object. It is an asteroid that, relative to Earth, orbits in a bean-shaped orbit that effectively describes a horseshoe, and that can transition into a quasi-satellite orbit. It has been incorrectly called "Earth's second moon". Cruithne does not orbit Earth and at times it is on the other side of the Sun. Its orbit takes it inside the orbit of Mercury and outside the orbit of Mars. Cruithne orbits the Sun in about 1 year but it takes 770 years for the series to complete a horseshoe-shaped movement around the Earth.

text: Despite these difficulties, utilizing the Yarkovsky effect is one scenario under investigation to alter the course of potentially Earth-impacting near-Earth asteroids. Possible asteroid deflection strategies include "painting" the surface of the asteroid or focusing solar radiation onto the asteroid to alter the intensity of the Yarkovsky effect and so alter the orbit of the asteroid away from a collision with Earth.  The OSIRIS-REx mission, launched in September 2016, will study the Yarkovsky effect on asteroid Bennu.

text: The asteroid belt may also be divided into the inner and outer belts, with the inner belt formed by asteroids orbiting nearer to Mars than the 3:1 Kirkwood gap (2.5 AU), and the outer belt formed by those asteroids closer to Jupiter's orbit. (Some authors subdivide the inner and outer belts at the 2:1 resonance gap (3.3 AU), whereas others suggest inner, middle, and outer belts; also see diagram).

text: The Nice model has undergone some evolution since its initial publication. In recent works the giant planets begin in a multi-resonant configurations consistent with numerical models of the early Solar System. After the resonant configuration is destabilized by interactions with the trans-Neptunian belt  a series of gravitational encounters occur. Among these are an encounter between one of the ice giants and Saturn propelling the ice giant inward onto a Jupiter-crossing orbit followed by an encounter with Jupiter which drives the ice giant outward. Referred to as a jumping-Jupiter scenario, these encounters quickly increase the separation between Jupiter and Saturn which has been found to be necessary to avoid excessively altering the eccentricity of the inner planets and the inclination distribution of the asteroids. This scenario also significantly reduces the fraction of asteroids removed from the main asteroid belt leaving a now nearly depleted inner band of asteroids as the primary source of the impactors of the LHB. In numerical simulations the ice giant is often ejected following its encounter with Jupiter leading some to propose that the Solar System began with five giant planets.

text: Colonization of asteroids would require space habitats. The asteroid belt has significant overall material available, the largest object being Ceres, although it is thinly distributed as it covers a vast region of space. Unmanned supply craft should be practical with little technological advance, even crossing 1/2 billion kilometers of cold vacuum. The colonists would have a strong interest in assuring that their asteroid did not hit Earth or any other body of significant mass, but would have extreme difficulty in moving an asteroid of any size. The orbits of the Earth and most asteroids are very distant from each other in terms of delta-v and the asteroidal bodies have enormous momentum. Rockets or mass drivers can perhaps be installed on asteroids to direct their path into a safe course.

text: Approximately one-third of the asteroids in the asteroid belt are members of an asteroid family. These share similar orbital elements, such as semi-major axis, eccentricity, and orbital inclination as well as similar spectral features, all of which indicate a common origin in the breakup of a larger body. Graphical displays of these elements, for members of the asteroid belt, show concentrations indicating the presence of an asteroid family. There are about 20–30 associations that are almost certainly asteroid families. Additional       groupings have been found that are less certain. Asteroid families can be confirmed when the members display common spectral features. Smaller associations of asteroids are called groups or clusters.

text: Based on an absolute magnitude of 13.2, the asteroid is calculated to measure between 6 and 14 kilometers in diameter, assuming an albedo in the range of 0.05 to 0.25. Since asteroids in the outer main-belt are mostly of a carbonaceous rather than of a silicaceous composition, with low albedos, typically around 0.06, the asteroid's diameter might be on the upper end of NASA's published conversion table, as the lower the body's reflectivity (albedo), the larger its diameter at a constant absolute magnitude (brightness).	The minor planet was named for Belgian former professional tennis player Justine Henin (b. 1985). Although her name contains no accent, the asteroid's official name does. Naming citation was published on 10 September 2003 (M.P.C. 49674).

After accomplishing this mission, they discover that Colossus’s sister, Illyana, is in a coma from a psychic hold placed on her by the Shadow King. Professor Xavier, Emma Frost, and Jean Grey enter the astral plane to save her. They succeed, but in the process Xavier is captured by the Shadow King.  After Xavier’s capture the X-Men learn that General William Kincaid, a leader in the anti-mutant movement, is building mutant-hunting Sentinels. Magneto travels to his base on Asteroid M, where he reveals his plan to cover the Earth in darkness. Meanwhile, the X-Men free Xavier who defeats the Shadow King in a psychic battle. The X-Men travel to Asteroid M, where they discover that the asteroid is on a collision course with Earth. After defeating Magneto they search for the Gravitron, a device used to pilot the asteroid. They encounter General Kincaid, who pilots Master Mold, a prototype sentinel larger and more powerful than other sentinels. After defeating General Kincaid, the X-Men locate the Gravitron and Magma uses her powers to steer the asteroid back into space. The X-Men's victory on Asteroid M is watched by Apocalypse who makes his upcoming plot from his base.

text: In January 2009, a photometric light-curve analysis by David Higgins at Hunters Hill Observatory, Australia, rendered a well-defined rotation period of  hours with a brightness variation of 0.56 in magnitude (U=3). Two months later, in March 2009, a second light-curve was obtained at the Via Capote Observatory, California, gave a period of  and an amplitude of 0.68 in magnitude (U=3-). According to the survey carried out by the NEOWISE mission of NASA's Wide-field Infrared Survey Explorer, the asteroid has a high albedo of 0.33 and a diameter of 6.7 kilometers, while the Collaborative Asteroid Lightcurve Link (CALL) calculates a diameter of 7.1 kilometers, based on an assumed albedo of 0.24, which is identical to the albedo of the Flora family's namesake, the asteroid 8 Flora.

text: Some astronomers counter this opinion 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. Although Jupiter does coexist with a large number of small bodies in its orbit (the Trojan asteroids), these bodies only exist in Jupiter's orbit because they are in the sway of the planet's huge gravity. Earth accretes or ejects near-Earth asteroids on million-year time scales, thereby clearing its orbit.  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). Since the orbits of these objects are entirely dictated by Neptune's gravity, Neptune is therefore gravitationally dominant.

text: Asteroid capture is the entering by an asteroid into an orbit around a larger planetary body. The larger body is said to have "captured" the asteroid, which thereafter is its natural satellite. Typically, asteroids that approach close to a planet are either thrown out into space or else hit the planet. However, occasionally the asteroid is captured in an orbit around the planet. This is possible with any planetary body given the right conditions. Researchers are working on ways for astronauts to capture an asteroid. On June 19, 2014, NASA reported that asteroid 2011 MD was a prime candidate for capture by the Asteroid Redirect Mission (ARM), perhaps in the early 2020s.

text: The current asteroid belt is believed to contain only a small fraction of the mass of the primordial belt. Computer simulations suggest that the original asteroid belt may have contained mass equivalent to the Earth.  Primarily because of gravitational perturbations, most of the material was ejected from the belt within about a million years of formation, leaving behind less than 0.1% of the original mass. Since their formation, the size distribution of the asteroid belt has remained relatively stable: there has been no significant increase or decrease in the typical dimensions of the main-belt asteroids.

text: The outer edge of the terrestrial region, between 2 and 4 AU from the Sun, is called the asteroid belt. The asteroid belt initially contained more than enough matter to form 2–3 Earth-like planets, and, indeed, a large number of planetesimals formed there. As with the terrestrials, planetesimals in this region later coalesced and formed 20–30 Moon- to Mars-sized planetary embryos; however, the proximity of Jupiter meant that after this planet formed, 3 million years after the Sun, the region's history changed dramatically. Orbital resonances with Jupiter and Saturn are particularly strong in the asteroid belt, and gravitational interactions with more massive embryos scattered many planetesimals into those resonances. Jupiter's gravity increased the velocity of objects within these resonances, causing them to shatter upon collision with other bodies, rather than accrete.

text: In 1981, a proposal for an asteroid mission was submitted to the European Space Agency (ESA). Named the Asteroidal Gravity Optical and Radar Analysis (AGORA), this spacecraft was to launch some time in 1990–1994 and perform two flybys of large asteroids. The preferred target for this mission was Vesta. AGORA would reach the asteroid belt either by a gravitational slingshot trajectory past Mars or by means of a small ion engine. However, the proposal was refused by ESA. A joint NASA–ESA asteroid mission was then drawn up for a Multiple Asteroid Orbiter with Solar Electric Propulsion (MAOSEP), with one of the mission profiles including an orbit of Vesta. NASA indicated they were not interested in an asteroid mission. Instead, ESA set up a technological study of a spacecraft with an ion drive. Other missions to the asteroid belt were proposed in the 1980s by France, Germany, Italy, and the United States, but none were approved. Exploration of Ceres by fly-by and impacting penetrator was the second main target of the second plan of the multiaimed Soviet Vesta mission, developed in cooperation with European countries for realisation in 1991–1994 but canceled due to the Soviet Union disbanding.

text: Three waves of fighters attack, alternating with three waves of cruisers. Enemy ships enter the screen one at a time. A ship flying off the left edge of the screen wraps around to the right side and attacks again. A new fighter can appear with others still on the screen, whereas a new cruiser will not come until the previous one is destroyed. The fighters pose only the threat of collision, while the cruisers fire on the player's ship. The fighter types are named Swoopers, LTFs (Light Triangular Fighters), and Saucers. The cruisers are called Urbites, Dramites, and Bynites. Each level ends with an asteroid belt, in which an array of asteroids advance on the ship and must be avoided or shot. At the end of each asteroid belt, any remaining asteroids are cleared away and the color of the ground is changed, then a new wave of Swoopers begins. Starting with level 4, the Swoopers are preceded by a random number of Killer Satellites, which come without the usual computer warning.

answers: asteroid family

text: Many asteroids have been placed in groups and families based on their orbital characteristics. Apart from the broadest divisions, it is customary to name a group of asteroids after the first member of that group to be discovered. Groups are relatively loose dynamical associations, whereas families are tighter and result from the catastrophic break-up of a large parent asteroid sometime in the past. Families have only been recognized within the asteroid belt. They were first recognized by Kiyotsugu Hirayama in 1918 and are often called Hirayama families in his honor.

text: 2001 YB5 is an Apollo near-Earth asteroid that passed a nominal distance of  from the Moon and  from Earth on 2002-Jan-07. The asteroid was approximately 300 meters in diameter; insignificant enough in size to be only discovered later that year in December 26, 2002 by NASA's Near-Earth Asteroid Tracking program (NEAT). The nearest proximity it has reached Earth by was 830,000 kilometres which is approximately twice the distance to the Moon. Based on limited observations, the asteroid may have a 2.5 hour rotation period and a Minimum Orbit Intersection Distance (MOID) from the Earth of . The findings of David Morrison of the NASA Ames Research Center claim that although YB5-sized objects in space commonly fly and orbit the Earth's proximity at such close distances annually, there are no indications of a YB5 collision on Earth as their predicted impact spans from about once every 20,000 to 30,000 years.

text: Although 135 Hertha has long been classified as an M-type asteroid based on its spectral properties, observations carried out by Rivkin et al. in 1996 using the IRTF at Mauna Kea Observatory have raised the possibility of reclassification.  The presence of a dip in the observed spectrum at 3 μm indicates that the surface is hydrated, suggesting that 135 Hertha should be reclassified as a W-type (a "wet M-type") asteroid.  Based on work carried out by Salisbury and Walter, the Rivkin study estimated the water content of the asteroid to be between 0.14 and 0.27 percent by mass; it should be noted, however, that this estimate is based on laboratory measurements and may not be applicable to asteroids in space.

text: In addition, Hayabusa was the first spacecraft designed to deliberately land on an asteroid and then take off again (NEAR Shoemaker made a controlled descent to the surface of 433 Eros in 2000, but it was not designed as a lander and was eventually deactivated after it arrived). Technically, Hayabusa was not designed to "land"; it simply touches the surface with its sample capturing device and then moves away. However, it was the first craft designed from the outset to make physical contact with the surface of an asteroid. Junichiro Kawaguchi of the Institute of Space and Astronautical Science was appointed to be the leader of the mission.

Shoemaker advanced the idea that sudden geologic changes can arise from asteroid strikes and that asteroid strikes are common over geologic time periods.  Previously, astroblemes were thought to be remnants of extinct volcanoes  — even on the Moon.

text: The Orion Asteroid Mission was a proposed NASA mission to a near-Earth asteroid (NEA) which would use the standard Orion spacecraft, and a landing module based on a modified Altair lunar lander. Most of its specific details are now deprecated by the cancellation of the Constellation Program and related designs. Such a mission could assess the potential value of water, iron, nickel, platinum and other resources on the asteroid; test possible ways to extract them; and possibly examine or develop techniques which could be used to protect the Earth from asteroid impacts. This would be the first manned mission to any extraterrestrial body besides the Moon, and would represent a step towards a manned mission to Mars.

text: Scientists' current understanding of asteroids depends greatly on meteorite samples, but it is very difficult to match up meteorite samples with the exact asteroids from which they came. Hayabusa will help solve this problem by bringing back pristine samples from a specific, well-characterized asteroid. Hayabusa bridged the gap between ground observation data of asteroids and laboratory analysis of meteorite and cosmic dust collections. Also comparing the data from the onboard instruments of the Hayabusa with the data from the NEAR Shoemaker mission will put the knowledge on a wider level.

text: The asteroid is a member of the Themis family, a large group of asteroids in the outer main-belt. It has a notable G-type spectra (or Cg-type in the SMASS taxonomy), similar to 1 Ceres, the largest asteroid and only dwarf planet in the asteroid belt. Dagmar orbits the Sun at a distance of 2.8–3.5 AU once every 5 years and 7 months (2,033 days). Its orbit shows an eccentricity of 0.11 and is nearly coplanar with the plane of the ecliptic, inclined by only 1 degree. It has a provisional rotation period of 12 hours, as measured by Italian astronomer Federico Manzini at th SAS observatory in Novara. Based on the surveys carried out by IRAS, Akari, WISE/NEOWISE, its albedo lies between 0.03 and 0.06.

text: A rotational light-curve was obtained by American astronomer Brian Warner at the U.S. Palmer Divide Observatory (716), Colorado, in October 2010. The light-curve gave a well-defined period of  hours with a relatively low brightness variation of 0.12 in magnitude (U=3). According to the survey carried out by the NEOWISE mission of NASA's Wide-field Infrared Survey Explorer, the asteroid has an outstandingly high albedo of 0.77 with a diameter of 3.2 kilometer, while the Collaborative Asteroid Lightcurve Link (CALL) assumes an albedo of 0.24, derived from the Flora family's largest member and namesake, the asteroid 8 Flora. Consequently, CALL calculates a much larger diameter of 5.9 kilometer, as the lower the albedo (reflectivity), the larger the body's diameter at a constant absolute magnitude (brightness).

text: The asteroid belonged to the Apollo group of near-Earth asteroids, and was roughly 40 days past perihelion (closest approach to the Sun) and had aphelion (furthest distance from the Sun) in the asteroid belt. Several groups independently derived similar orbits for the object, but with sufficient variance to point to different potential parent bodies of this meteoroid. The Apollo asteroid  is one of the candidates proposed for the role of the parent body of the Chelyabinsk superbolide. Other published orbits are similar to the 2-kilometre-diameter asteroid  to suggest they had once been part of the same object; they may not be able to reproduce the timing of the impact.

text: Aten asteroids are defined by having a semi-major axis of less than one astronomical unit (AU), the distance from the Earth to the Sun. They also have an aphelion (furthest distance from the Sun) greater than 0.983 AU. Asteroids' orbits can be highly eccentric. An Aten orbit need not be entirely contained within Earth's orbit, as nearly all known Aten asteroids have their aphelion greater than 1 AU although their semi-major axis is less than 1 AU. Observation of objects inferior to the Earth's orbit is difficult and this difficulty may be the cause of some sampling bias in the apparent preponderance of eccentric Atens. Aten asteroids account for only about 6% of the known near-Earth asteroid population. Many more Apollo-class asteroids are known than Aten-class asteroids, possibly because of the sampling bias.

text: On July 1994, Comet Shoemaker–Levy 9 was a comet that broke apart and collided with Jupiter, providing the first direct observation of an extraterrestrial collision of Solar System objects. The event served as a "wake-up call", and astronomers responded by starting programs such as Lincoln Near-Earth Asteroid Research (LINEAR), Near-Earth Asteroid Tracking (NEAT), Lowell Observatory Near-Earth Object Search (LONEOS) and several others which have drastically increased the rate of asteroid discovery.

text: In October 2013, COPUOS's Scientific and Technical Subcommittee approved several measures, later approved by the UN General Assembly in December, to deal with terrestrial asteroid impacts, including the creation of an International Asteroid Warning Network (IAWN) plus two advisory groups: the Space Missions Planning Advisory Group (SMPAG), and the Impact Disaster Planning Advisory Group (IDPAG). The IAWN warning network will act as a clearing house for shared information on dangerous asteroids and for any future terrestrial impact events that are identified. The Space Missions Planning Advisory Group will coordinate joint studies of the technologies for deflection missions, and as well provide oversight of actual missions. This is due to deflection missions typically involving a progressive movement of an asteroid's predicted impact point across the surface of the Earth (and also across the territories of uninvolved countries) until the NEO is deflected either ahead of, or behind the planet at the point their orbits intersect. An initial framework of international cooperation at the UN is needed, said Schweickart, to guide the policy makers of its member nations on several important NEO-related aspects. However, as asserted by the Foundation, the new UN measures only constitute a starting point. To be effective they will need to be enhanced by further policies and resources implemented at both the national and supernational levels.

text: 2013 LA2 is a Centaur and most likely an extinct comet with the highest orbital inclination of any known asteroid, 175.189 degrees, which gives it a retrograde orbit, inclined 4.81 degrees to the ecliptic. The asteroid's orbit takes if from the outer main asteroid belt to between the orbit of Saturn and Uranus. However the asteroid's orbit is poorly determined, and contrary to the JPL, the minor planet center's orbit puts it with an aphelion near the orbit of Saturn. The asteroid was observed 43 times over a 25-day interval between June 1, 2013 and June 26, 2013.

However the asteroid's orbit is poorly determined, and contrary to the JPL, the minor planet center's orbit puts it with an aphelion near the orbit of Saturn. The asteroid was observed 43 times over a 25-day interval between June 1, 2013 and June 26, 2013.

text: There are millions of asteroids, many thought to be the shattered remnants of planetesimals, bodies within the young Sun's solar nebula that never grew large enough to become planets. The large majority of known asteroids orbit in the asteroid belt between the orbits of Mars and Jupiter, or are co-orbital with Jupiter (the Jupiter trojans). However, other orbital families exist with significant populations, including the near-Earth objects. Individual asteroids are classified by their characteristic spectra, with the majority falling into three main groups: C-type, M-type, and S-type. These were named after and are generally identified with carbon-rich,  metallic, and silicate (stony) compositions, respectively. The size of asteroids varies greatly, some reaching as much as  across.
