The asteroid belt is an area between the orbits of Jupiter and Mars that contains many small, rocky bodies. Asteroid, also called minor planet or planetoid, any of a host of small bodies, about 1,000 km (600 miles) or less in diameter, that orbit the Sun primarily between the orbits of Mars and Jupiter in a nearly flat ring called the asteroid belt. While most of the asteroid belt is made up of rocky objects, Ceres is an icy body. Objects that exist within the belt are divided into 8 subgroups, with each one named after the main asteroids within the group: Most of this ancient space rubble can be found orbiting the Sun between Mars and Jupiter within the main asteroid belt. It is because of their small size and large numbers relative to the major planets that asteroids are also called minor planets. The current known asteroid count is: . The number of bodies grows rapidly as the size decreases.Based on IRAS data there are … Asteroids range in size from Vesta — the largest at about 329 miles (530 kilometers) in diameter — to bodies that are less than 33 feet (10 meters) across. Jupiter does have very faint rings, but these are not called an "asteroid belt". The average distance between objects in the Asteroid Belt is quite large. It spans about 140 million miles across. The belt is about 1 AU thick. The Asteroid Belt is located in an area of space between the orbits of Mars and Jupiter. This region looks like a belt, or a ring around the Sun. The Main Belt of the asteroid belt is between Jupiter and Mars and is around 2-4 times the Sun-Earth distance. Load More

The asteroid belt is a region in the solar system between the orbits of Mars and Jupiter where almost all the asteroids are concentrated. That places it between 2.2 and 3.2 astronomical units (AU) from the Sun.
