Until 2001, most basaltic bodies discovered in the asteroid belt were believed to originate from the asteroid Vesta (hence their name V-type), but the discovery of the asteroid 1459 Magnya revealed a slightly different chemical composition from the other basaltic asteroids discovered until then, suggesting a different origin.

Juno (minor-planet designation: 3 Juno) is a large asteroid in the asteroid belt.Juno was the third asteroid discovered, in 1804, by German astronomer Karl Harding. [15] It is tied with three other asteroids as the thirteenth largest asteroid, and it is one of the two largest stony asteroids, along with 15 Eunomia.
152830 Dinkinesh (provisional designation 1999 VD 57) is a binary main-belt asteroid about 790 meters (2,600 feet) in diameter. It was discovered by the Lincoln Near-Earth Asteroid Research (LINEAR) survey at Socorro, New Mexico on 4 November 1999.
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°.
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.
In the main asteroid belt, there appear to be two primary populations of asteroid: a dark, volatile-rich population, consisting of the C-type and P-type asteroids, with albedos less than 0.10 and densities under 2.2 g/cm 3, and a dense, volatile-poor population, consisting of the S-type and M-type asteroids, with albedos over 0.15 and densities ...
Main-belt comet–asteroid discovered to have a coma on November 26, 2005 The above table lists only numbered asteroids that are also comets. Note there are several cases where a non-numbered minor planets turned out to be a comet , e.g. C/2001 OG108 (LONEOS) , which was provisionally designated 2001 OG 108 .
