Here's a bit more about them:
* What are they? Asteroids are rocky, airless bodies that orbit the Sun. They are much smaller than planets, but they can still be quite large - some are hundreds of miles across.
* Where are they found? The vast majority of asteroids reside in the asteroid belt, a region between Mars and Jupiter. This belt is a region of space where the gravitational pull of Jupiter prevented a planet from forming.
* How many are there? There are millions of asteroids in the asteroid belt, and they range in size from dust particles to hundreds of miles across.
* Notable examples: Some of the most famous asteroids include Ceres (the largest asteroid), Vesta (a bright and heavily cratered asteroid), and Pallas (the second-largest asteroid).
