Recently-discovered members of this include Quaoar (KWAY-o-arr) and, possibly, Sedna. It was first predicted as being like another similarly-named structure, but with icy rather than rocky objects. Unlike the area it is often confused with, all objects in it are confined roughly to the plane of the ecliptic. Large members of it are referred to as KBO's, while small ones are just called comets. Beginning somewhere before the orbit of Neptune and extending out to approximately 50 AU's, this is, for ten points, the area which is home to short-peri
