On average the distance between the asteroids is about 965,600 km (600,000 miles), [68] [69] although this varies among asteroid families and smaller undetected asteroids might be even closer. The total mass of the asteroid belt is estimated to be 2.39 × 10 21 kg, which is 3% of the mass of the Moon. [ 2 ]
The asteroid and comet belts orbit the Sun from the inner rocky planets into outer parts of the Solar System, interstellar space. [ 16 ] [ 17 ] [ 18 ] An astronomical unit , or AU, is the distance from Earth to the Sun, which is approximately 150 billion meters (93 million miles). [ 19 ]

Below are the descriptions of the three largest bodies in the asteroid belt. They are all considered to be relatively intact protoplanets, a precursor stage before becoming a fully-formed planet (see List of exceptional asteroids): [143] [144] [145] Ceres (2.55–2.98 AU) is the only dwarf planet in the asteroid belt.

The rest of the near-Earth asteroids are driven out of the asteroid belt by gravitational interactions with Jupiter. [27] [124] Many asteroids have natural satellites (minor-planet moons). As of December 2024, 104 NEAs were known to have at least one moon, including five known to have two moons. [125]
Didymos probably formed in our solar system's main asteroid belt, between the planets Mars and Jupiter, and then was knocked into the inner solar system, the researchers said. ... at a distance of ...
intermediate main-belt (2.5 AU < a < 2.82 AU) outer main-belt (a > 2.82 AU) A plot of inner solar system asteroids and planets as of 2006 May 9, in a manner that exposes the Kirkwood gaps. Similar to the position plot, planets (with trajectories) are orange, Jupiter being the outer most in this view. Various asteroid classes are colour coded ...
