The asteroid belt is a torus-shaped region in the ... The asteroid belt formed from the primordial solar nebula as a group of ... "The Asteroid Belt". Universe Today.
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 asteroid belt initially contained more than enough matter to form 2–3 Earth-like planets, and, indeed, a large number of planetesimals formed there. As with the terrestrials, planetesimals in this region later coalesced and formed 20–30 Moon- to Mars-sized planetary embryos; [56] however, the proximity of Jupiter meant that after this ...
Another study published in August found that this object formed beyond Jupiter and probably migrated inward to become part of the main asteroid belt before being sent hurtling toward Earth ...
Most highly inclined known main-belt asteroid from August 17, 1998, to October 19, 1998 MPC (88043) 2000 UE 110: 51.998° October 29, 2000 First main-belt asteroid discovered and numbered to have an inclination greater than 50°. MPC (138925) 2001 AU 43: 72.132° January 4, 2001 A Mars-crosser and near-Earth object. MPC (127546) 2002 XU 93: 77 ...
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.
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 impactor likely formed in the outer solar system before migrating to the asteroid belt. A team of researchers think they know the origin of a massive space rock that hit Earth and killed off ...
