The asteroid belt is a large disc-shaped ring with large solid bodies such as asteroids (minor planets).

It divides the sequence of eight planets into two parts.

The four planets are before the asteroid belt towards the Sun are Mercury, Venus, Earth and Mars and the four planets are ahead of the asteroid belt are Jupiter, Saturn, Uranus and Neptune.

Size of asteroid belt:-

The asteroid belt is about 150 million km thick and approximately 2.2 AU from the sun.
The estimated mass of the asteroid belt is 2.39 × 10²¹ kg while only mass of the Earth is larger than the mass of the entire asteroid belt and is about 5.9×10²⁴kg .

Materials in asteroid belt:-Most of the asteroid belt material was already lost during the early 100 million years of the solar system.

It mainly consists of three types of bodies in which the first type is C-type that are rich in carbon, the second type of bodies are S-type which is silicate rich body and the third type consists of M-type bodies which contain metals like iron and nickel.

The asteroid belt consists of about 1-1.7 million asteroids in a small area of 1 km or more in diameter and this data was traced by infrared wavelengths.

The asteroid belt has large bodies whose size is about 950 km and as short as dust particles.
There is also a dwarf planet named Ceres in the asteroid belt.
There are about 200 known asteroids have a diameter of more than a hundred kilometers in size.

Facts:-Meteroids entering the Earth’s atmosphere are also mostly from the asteroid belt. Meteroids are large bodies made up of ice and dust particles.
