          COMETS and CRATERS is an overview of moving objects within the Universe such as Comets and Asteroids. Asteroids however behave quite different. Many are comprised of loosely held together particles making just a big pile of small rocks compacted together in one giant clump. Some asteroids have their own moon, or satellite companion.
