Original: 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.
