Theory:

Not only the planets but also some other celestial bodies revolve around the Sun. Those are the asteroids, comets, meteors, and meteorites. The motion of these objects is governed by the gravitational force of the Sun.
Asteroids:
Asteroids are rocky celestial objects that orbit in space and revolve around the Sun in a particular path.
The asteroids are rocks of various sizes. The biggest ones can be hundreds of kilometres in diameter, whereas the smallest ones can be hundreds of metres. With the help of a large telescope, these objects can be seen.

Asteroid belt:
After the planet Mars, a large gap is present between the orbits of Mars and Jupiter. These asteroids form a belt-like structure between Mars and Jupiter. This asteroid belt looks like a dividing line between the inner rocky planets and the outer gaseous giants.
