The vast majority of asteroids in the solar system are found in the asteroid belt, a region of interplanetary space located between the orbits of Mars and Jupiter.123

Within this belt, most asteroids occupy orbits with mean distances from the Sun between 2.06 and 3.28 astronomical units. These objects are considered the leftover building blocks from the formation of the solar system's rocky planets. While the asteroid belt serves as the primary reservoir, asteroids are also found in other regions, such as the Hungaria group and various groups of Trojan asteroids that share orbits with major planets.425
