explain to me more about "Asteroid"?

Answer 1

a little earth not from earth.

Answer 2

An asteroid is a predominantly rocky body that orbits around its star. In our solar system, asteroids are the best known class of minor planet (or planetoid). They are much smaller than even the small major planets such as Mercury or Mars. The vast majority of the asteroids are found within the main asteroid belt, with elliptical orbits between those of Mars and Jupiter. It is thought that asteroids are remnants of the protoplanetary disc, and in this region the incorporation of protoplanetary remnants into the planets was prevented by large gravitational perturbations induced by Jupiter during the formative period of the solar system. Some asteroids have moons

Answer 3

asteroid, planetoid,or minor planet,small body orbiting the sun. More than 10,000 asteroids have orbits sufficiently well known to have been cataloged and named; thousands more exist. Most asteroids are irregularly shaped, unlike the spherically shaped major planets. The largest asteroids, Quaoar (diameter c.800 mi/1,300 km) and Ixion and Varuna (both c.750 mi/1,200 km), reside in the Kuiper belt (see comet) and are about half the size of Pluto. The largest main-belt asteroid, Ceres, has a diameter of c.630 mi (1,000 km); the three next largest are Pallas, Vesta, and Juno. Only Vesta can be seen with the naked eye. Many asteroids are no larger than a few kilometers; in 1991, an asteroid only 33 ft (10 m) in diameter was found. Many asteroids are so small that their sizes cannot be measured directly; in many cases, their sizes have been estimated from their brightness and distances. The average orbital distance of the asteroids from the sun is about 2.9 astronomical units (AU).

The orbits of most asteroids lie partially between the orbits of Mars and Jupiter. These so-called main-belt asteroids are divided into subgroups named for the main asteroid in the grouping: Hungarias, Floras, Phocaea, Koronis, Eos, Themis, Cybeles, and Hildas. The near-earth asteroids, which closely approach the earth, are classed as Atens (with orbits between the earth and the sun), Apollos (with orbits similar to that of the earth), and Amors (with orbits between the earth and Mars). Two groups of asteroids share Jupiter's orbit; they are known as Trojan asteroids. In 1990, a similar asteroid was found in the orbit of Mars. Centaurs are asteroids with orbits in the outer solar system

Answer 4

An asteroid would be...

1. Any of the small rocky celestial bodies found especially between the orbits of Mars and Jupiter or anywhere else in space.

2. Resembling or of a star.

3. Any of a class (Asteroidea) of echinoderms that have a body of usually five arms radially arranged about a central disk and feed largely on mollusks (as oysters) -- called also sea star

4. The region of interplanetary space between the orbits of Mars and Jupiter in which most asteroids are found

Answer 5

An asteroid is a rock that orbits the sun. A possible loation of the orbit would be the asteroid belt between mars and jupiter. They are known as minor planets.

Answer 6

Any of numerous small celestial bodies that revolve around the sun
and also it is composed of rock and metal that revolve around the sun ^_^ you can mainly find them between jupiter and mars, also it is believed that the moon was formed from the earth (because the moon is like an asteroid)
(also just adding this in, an asteroid is NOT made up of ice or dust, that is what a comet is made up of) i hope this helped ^_^

Answer 7

A huge rock "flying" around outerspace.

Answer 8

Chunk of rock/ ice out in space. Hit planet. Go 'BOOM!' Any more questions...?

Answer 9

What do you need to know?
