The average distance between asteroids in the main belt is about 600,000 miles. Ceres, the largest and most massive, is 590 miles wide. It contains almost one-third of the total mass of all the asteroids.
The asteroid belt occupies the orbit between Mars and Jupiter, between 2.3 and 3.3 AU from the Sun. It is thought to be remnants from the Solar System's formation that failed to coalesce because of the gravitational interference of Jupiter.
