The asteroid belt is the region of the Solar System located roughly between the orbits of the planets Mars and Jupiter.eres, the asteroid belt's only dwarf planet, is about 950 km in diameter, whereas Vesta, Pallas, and Hygiea have mean diameters of less than 600 km.
Asteroids are thought to be leftover material from the formation of our Solar System. Most are found in the Asteroid Belt, a doughnut-shaped ring which lies between the orbits of Mars and Jupiter. Astronomers have also identified a group of asteroids whose orbits cross Earth's orbit.
