text: However , the difference between the Kuiper belt and the scattered disc is not clearcut , and many astronomers see the scattered disc not as a separate population but as an outward region of the Kuiper belt . Another term used is `` scattered Kuiper belt object '' ( or SKBO ) for bodies of the scattered disc .
simplified: The part of the scattered disc closest to the sun is in an area of space called the Kuiper belt .
