All Trans-Neptunian and Outer Solar System Objects

Small Body Beyond a Boundary Arc

Bodies and regions beyond the orbit of Neptune, including Kuiper Belt objects and the outer regions themselves where an entry describes the region rather than one discrete body. Belongs here: any object or named region whose defining location is trans-Neptunian, not yet massive enough or not confirmed as a dwarf planet. Does not belong here: confirmed dwarf planets in this same region, such as Pluto and Eris, grouped under Dwarf Planets, since dwarf-planet status is the more specific and more useful grouping once a body has been confirmed.
