The rocky objects revolving around the sun that are too small and numerous to be called planets are called asteroids.

Here's a little more about them:

* Location: Most asteroids reside in the asteroid belt, located between the orbits of Mars and Jupiter.

* Size: Asteroids range in size from a few meters across to hundreds of kilometers in diameter.

* Composition: They are mostly made of rock, metal, and ice.

* Number: There are millions of asteroids, and scientists estimate that there are likely billions more that haven't been discovered yet.
