Comets are often described as "dirty snowballs" The Kuiper Belt and the more distant Oort Cloud are the solar system's two sources of comets Comets are solar-system leftovers that spend most of their lives far beyond the realm of the planets. We know about them because a few periodically visit the inner solar system, where they can decorate our night skies in spectacular fashion. Comet Hale-Bopp put on one of the best shows of this century in 1997.
