Vanth
Vanth is the single known natural satellite of the plutino and likely dwarf planet Orcus. The moon orbits Orcus "in a tight precise circle", with a period of approximately 10 days. The satellite does not resemble other known collisional satellites because its spectrum is very different of that of its primary. Vanth may thus be a captured Kuiper belt object.
