Asteroids | Crash Course Astronomy

Asteroids are chunks of rock or metal, or both, that were once part of a planet, but were destroyed after collisions. Most asteroids orbit the Sun between Mars and Jupiter, but some get near the Earth. The biggest asteroid, Ceres, is far smaller than the Moon but still big enough to be round and have undergone differentiation.
