Here's a little more about asteroids:

* Location: They mostly reside in the asteroid belt between Mars and Jupiter, but some have orbits that bring them closer to the Sun or Earth.

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

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

* Formation: They are remnants from the early solar system that never formed into a planet.
