Orcus

Dwarf Planet Orcus



Orcus is a trans-Neptunian plutino dwarf planet located in the Kuiper belt with a large moon, Vanth. It is similar to Pluto in several respects and is seen as the "anti-Pluto" as it is also in an orbital resonance with Neptune, just in opposite phase from Pluto. It is not officially recognized as a dwarf planet yet but meets all the requirements of one.
