What Is a Meteor?
9. Asteroids
Asteroids are basically defined as a rocky body that orbits the sun. Although larger than meteoroids, they are also considerably smaller than even the smallest of planets. As they are in a fixed orbit, they usually present no danger to our planet as they will not come close.

Most of the asteroids in our solar system are found in an asteroid belt between the planets Mars and Jupiter and this is known simply as the main asteroid belt. There is also the Kuiper belt, which is a vast region of asteroids that starts from close to Neptunes orbit and continues past Pluto.
