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 ]
[66] [67] An analysis of the TNO data available prior to September 2023 shows that the distribution of objects at the outer rim of the classical Kuiper belt resembles that of the outer main asteroid belt with a gap at about 72 AU, far from any mean-motion resonances with Neptune; the outer main asteroid belt exhibits a gap induced by the 5:6 ...
This list includes few examples since there are about 589 asteroids in the asteroid belt with a measured radius between 20 and 49 km. [177] Many thousands of objects of this size range have yet to be discovered in the trans-Neptunian region.

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 ...
Earth tends to pull asteroids into partial or full orbits around it regularly before they are flung back out into space. For instance, one such space rock 2022 NX 1 was a short-lived “mini-moon ...
10 Hygiea is a major asteroid located in the main asteroid belt.With a mean diameter of between 425 and 440 km and a mass estimated to be 3% of the total mass of the belt, [11] it is the fourth-largest asteroid in the Solar System by both volume and mass, and is the largest of the C-type asteroids (dark asteroids with a carbonaceous surface) in classifications that use G type for 1 Ceres.
