SOLAR SYSTEM

Detailed explanation-1: -Main Asteroid Belt : The majority of known asteroids orbit within the asteroid belt between Mars and Jupiter, generally with not very elongated orbits. The belt is estimated to contain between 1.1 and 1.9 million asteroids larger than 1 kilometer (0.6 miles) in diameter, and millions of smaller ones.

Detailed explanation-2: -This asteroid belt is also called the main asteroid belt or main belt to distinguish it from other asteroid populations in the Solar System.

Detailed explanation-3: -In the region between Mars and Jupiter, it appears that one or more planets could have formed, but the gravity from Jupiter kept pulling things apart. Instead of forming a single planet, the material in this region was only ever able to form into asteroid-sized objects.
