The Asteroid Belt

The asteroid belt is located between the orbits of the planets Mars and Jupiter. In this specific region, you will find the vast majority of asteroids. These asteroids are also known as minor planets or planetoids. Some major asteroids in the asteroid belt are Ceres, Vesta, Pallas and Hygiea.

These four asteroids comprise around half of the mass of the entire asteroid belt. Ceres is the only asteroid which is categorized as a dwarf planet as it is the largest asteroid in the inner solar system.
