This asteroid belt is also called the main asteroid belt or main belt to distinguish it from other asteroid populations in the Solar System. [ 1 ] The asteroid belt is the smallest and innermost known circumstellar disc in the Solar System.
Inner asteroid belt, inside of the strong Kirkwood gap at 2.50 AU due to the 3:1 Jupiter orbital resonance. The largest member is 4 Vesta . It apparently also includes a group called the main-belt I asteroids which have a semi-major axis between 2.3 AU and 2.5 AU and an inclination of less than 18°.
Asteroid and dwarf planet: The first asteroids to be discovered were accepted as planets in the Copernican system, since they directly orbited the Sun. By 1855 the number of known bodies in the asteroid belt had grown to 15, at which point

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]
The Massalia asteroid family, formed about 40 million years ago, accounts for a class of meteorites called L chondrites that represent 37% of known Earth meteorites, the research found.
