Populated by the likes of Sedna and the plutinos, including Pluto itself, FTP what is this region of astronomical objects lying beyond the orbit of Neptune, thought by some to be the source of short-period comets?
Objects not at either edge of this region are known as "cubewanos," from the name of the first object discovered in its class, 1992 QB1. Objects that have been found in this region include 2005 FY9, nicknamed "Easter Bunny," and 28978 Ixion, while the Centaurs are believed to be "refugees" from this region. Its outer edge extends approximately to the 1:2 resonance, and the inner edge is defined by the 2:3 resonance at 48 AU.
