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 majority of known asteroids are in the asteroid belt, a large donut-shaped ring located between the orbits of Mars and Jupiter, and orbit approximately 2 to 4 AU (186 million to 370 million miles/300 million to 600 million kilometers) from the Sun.
