Asteroid Formations

The asteroid has a very interesting way of forming. The first thing that happens is the gas and dust collect. Then small objects begin to form. This happens because of accretion and gravity. Accretion is the growth of an object because of the matter that collides with it and makes it bigger. It is very simalar to fusion. Finally when the large object can't accrete anymore because the planets Jupiter and Mars prevent objects from sticking together.
