what is the asteroid belt composition
The first is by composition. The typical composition of an asteroid depends on its distance from the Sun. At the outer edges of the asteroid belt, that is between three and three and a half times further from the Sun than the Earth, over eighty percent of the asteroids are known as C-type.rom piles of 'rubble' to complex mixtures of metals, and carbon and silicon compounds, asteroids are not just dull grey lumps of cratered rock... We find that asteroids are fascinating objects, varying in composition and shape.
