Located outside of Mars’ orbit, the asteroid belt is comprised of different sizes of space rocks of unknown origin. In the past, some scientists proposed that the rocks were remnants of a planet that exploded. However, that theory doesn’t support the fact that the rocks appear to have come from different parent bodies.

Scientists have also proposed that the rocks were originally part of small, developing planets that never completely formed. This theory is problematic since there are not enough rocks in the belt to create a planetary mass. However, it is possible that the belt is comprised of remnants of other existing planets. Some of the rocks in the belt may have come from other planets by breaking away from them during an early period of instability in the solar system.

Although scientists remain uncertain about how the asteroid belt was formed, it is believed that the rocks are likely to stay located within the belt, since the orbits of Mars and Jupiter are stabilized.
