Astronomers estimate that the cloud may extend out another light-year—nearly one quarter the distance to the closest star. Both the Oort Cloud and the closer Kuiper Belt—just outside the orbit of Neptune—are filled with icy debris left over from the formation of the planets. Every so often something shakes one of these dirty snowballs loose and sends it careening toward the sun. Each comet carries with it a history of our solar system and teaches astronomers something new about where we came from.
