This illustration shows that the Kuiper Belt is shaped like a disk [see inset diagram] and resides within the shell-like structure of the Oort Cloud. Located on the outskirts of the solar system, the Kuiper Belt is a "junkyard" of countless icy bodies left over from the solar system's formation. The Oort Cloud is a vast shell of billions of comets. The inset diagram compares Pluto's orbit with a Kuiper Belt binary object called 1998 WW31. The Kuiper Belt [the fuzzy disk] extends from inside Pluto's orbit to the edge of the solar system.

Object Name: 1998 WW31
