Main Asteroid Belt - Solstation
On October 4, 2010, some astronomers announced that asteroid 21 Lutetia may be covered by a 2,000-feet (600-meter) deep layer of dusty debris generated by billions of years of meteorite impacts (Jonathan Amos, BBC News, October 4, 2010).

The Asteroid Belt - Starchild
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.

Asteroid Belt - World Mysteries
Leading models of solar system formation hold that as the Sun gathered itself together out of a cloud of gas and dust, the leftovers settled into a vast disk that rotated around the newborn star and gradually flattened out.

Asteroid Belt Facts: Interesting Facts about the Asteroid Belt - Space Facts
The vast majority of asteroids in the solar system are found in a region of the solar system out beyond Mars. They form the Asteroid Belt. Others orbit in near-Earth space and a few migrate or are thrown out to the outer solar system by gravitational interactions. The four largest asteroids in the belt are Ceres, Vesta, Pallas, and Hygiea. They contain half the mass of the entire belt. The rest of the mass is contained in countless smaller bodies.

Asteroid Belt - Wikipedia, the Free Encyclopedia
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.
