Asteroid From Wikipedia, the free encyclopedia Jump to: navigation search For other uses, see Asteroid (disambiguation) 253 Mathilde , a C-type asteroid NEAR Shoemaker probe. Asteroids (from Greek ”star” + “like”, in form), sometimes grouped with Centaurs Neptune trojans and trans-Neptunian objects into minor planets or planetoids , are a class of small Solar System bodies in orbit around the Sun . The term "asteroid" was historically applied to any astronomical object orbiting the Sun that was not observed to have the characteristics of an active comet or a planet, but it has increasingly come to particularly refer to the small rocky and metallic bodies of the inner Solar System and out to the orbit of Jupiter . As small objects in the outer Solar System have begun to be discovered their observed composition differs from the objects historically termed asteroids. Harbouring predominantly volatiles -based material similar to comets rather than the more familiar rocky or metallic asteroids, they are often distinguished from them. Like most other small Solar System bodies the asteroids are thought to be remnants of planetesimals , material within the young Sun’s solar nebula that have not grown large enough to form planets The large majority of known asteroids orbit in the main asteroid belt between the orbits of Mars and Jupiter, however many different orbital families exist with significant populations including

ASTEROIDS Are also known as the Minor Planets. Orbit the Sun mainly between the orbits of Mars and Jupiter. Usually range in size from 1 kilometer to 1000 kilometers across. Are difficult to observe because of their small size. Gaspra (above) and Ida (right) are two known Asteroids. Ceres, Pallas, Juno and Vesta are some other of the larger Asteroids. Sometimes have moons that orbit them. Notice the small moon that orbits Ida (right).

Asteroids The following graph shows the number density of asteroids as a funciton of their distance from the sun. Note that there are peaks and throughs in this density due to exact periodic resonance with Jupiter. Also, the peak above 5 AU is due to the Trojan Asteroids. These asteroids are located approximately at the leading and trailing Lagrangian (i.e. Trojan) of Jupiter's Orbit.

SEND YOUR FEEDBACK SCIENCE FAQs Asteroids 'Minor planets' can have major impact CBC News In early March 2009 an asteroid whipped over the Pacific Ocean near Tahiti travelling 72,000 kilometres from the Earth, according to NASA's Near Earth Object program. The asteroid could be seen from Australia, Japan and China. The space rock was first observed by Rob McNaught at Siding Spring Observatory in Australia, when it was "a dim speck about 1.5 million kilometres away." Asteroids pass near the Earth's atmosphere frequently — the next one, Asteroid 4179 Toutatis — is expected on Dec. 12, 2012. What is an asteroid? Asteroids, also known as "minor planets," are metallic, rocky bodies orbiting the sun that are too small to be classified as planets. This false-colour picture of asteroid 951 Gaspra is a mosaic of two images taken by the Galileo spacecraft from a range of 5,300 kilometres, some 10 minutes before its closest approach to the spacecraft on Oct. 29, 1991. (NASA/NEO) Unlike comets, which are thought to have originated in the outer solar system beyond Jupiter, asteroids are closer to the sun. Most asteroids are gathered in belts between Mars and Jupiter, about 300 to 600 million kilometres away from the sun, or roughly two to four times the distance from the Earth to the sun.

10. Asteroids� L� Asteroid Facts, Pictures And Information Several hundred thousand asteroids have been discovered and given provisional designations so far. Thousands more are discovered each year. http://nineplanets.org/asteroids.html

Asteroids On the first day of January 1801, Giuseppe Piazzi discovered an object which he first thought was a new comet. But after its orbit was better determined it was clear that it was not a comet but more like a small planet. Piazzi named it Ceres, after the Sicilian goddess of grain. Three other small bodies were discovered in the next few years (Pallas, Vesta, and Juno). By the end of the 19th century there were several hundred. Several hundred thousand asteroids have been discovered and given provisional designations so far. Thousands more are discovered each year. There are undoubtedly hundreds of thousands more that are too small to be seen from the Earth . There are 26 known asteroids larger than 200 km in diameter. Our census of the largest ones is now fairly complete: we probably know 99% of the asteroids larger than 100 km in diameter. Of those in the 10 to 100 km range we have cataloged about half. But we know very few of the smaller ones; there are probably considerably more than a million asteroids in the 1 km range. The total mass of all the asteroids is less than that of the Moon 11 comets and asteroids have been explored by spacecraft so far, as follows: ICE flyby of Comet Giacobini-Zinner. Multiple flyby missions to Comet Halley. Giotto (retarget) to Comet Grigg-Skellerup. Galileo flybys of asteroids Gaspra and Ida (and Ida satellite Dactyl). NEAR-Shoemaker flyby of asteroid Mathilde on the way to orbit and land on Eros. DS-1 flybys of asteroid Braille and Comet Borrelly. Stardust flyby of asteroid Annefrank and recent sample collection from Comet Wild 2. For future we can expect: Hayabusa (MUSES-C) to asteroid Itokawa, Rosetta to Comet Churyumov-Gerasmenko, Deep Impact to Comet Tempel 1, and Dawn to orbit asteroids Vesta and Ceres.

11. Asteroids: Debris Of The Solar System asteroids are the leftovers of the rocks and ice which made the planets. http://starryskies.com/solar_system/Asteroids/asteroids_top.html

ASTEROIDS Debris in the Solar System When the Solar System formed, not everything was used to make planets and moons, leftovers became asteroids and comets. They are perhaps the oldest remnants of the early Solar System and what we learn from them tells us about our own early history. Most of the asteroids lie between the orbits of Mars and Jupiter, but some have very elliptical orbits which bring them very close to Earth. They range in size from about 30% the diameter of our moon to pebble sized objects. In number, there are probably billion of asteroids in the solar system. The largest known asteroid is Ceres which was the first asteroid to be discovered in 1801. Ceres is about 1/3 the size of our moon. It can be seen in amateur telescopes if one knows where and when to look. Most asteroids are of the small irregular variety. None of them are large enough to have high enough gravity to pull themselves into spherical shape. Images of the same asteroid vary in brightness which confirms the irregular shape. The Galileo spacecraft passed through the asteroid belt twice on its way to Jupiter. The spacecraft passed only 16.000 km from the asteroid Gaspra in 1990 and returned excellent images. Gaspra is an oblong world measuring 20 by 12 by 11 km. It is covered by a layer of shattered soil about a meter deep. There are also numerous craters on Gaspra's surface.

Listen The Asteroid Belt The dwarf planet called Ceres orbits the Sun in the asteroid belt. An asteroid is a bit of rock. It can be thought of as what was "left over" after the Sun and all the planets were formed. Most of the asteroids in our solar system can be found orbiting the Sun between the orbits of Mars and Jupiter. This area is sometimes called the "asteroid belt". Think about it this way: the asteroid belt is a big highway in a circle around the Sun. Think about the asteroids as cars on the highway. Sometimes, the asteroid cars run into one another. When this happens, the asteroids may break up into smaller asteroids. Scientists think that most asteroids are the result of collisions between larger rocky space bodies. Asteroids can be a few feet to several hundred miles wide. The belt probably contains at least 40,000 asteroids that are more than 0.5 miles across. If an asteroid is captured by the gravitational pull of a planet, the asteroid can be pulled out of the belt and go into orbit as a moon around the planet that pulled on it. A Question Between what two planets will you find the asteroid belt?
