Ancient Space Rubble
Asteroids are rocky fragments left over from the formation our the solar system about 4.6 billion years ago. Most of these chunks of space rubble, sometimes called minor planets, can be found orbiting the Sun in a belt between the orbits of Mars and Jupiter. The Asteroid Belt or Main Belt probably contains millions of asteroids.
