(90482) Orcus (Orkus; frühere Bezeichnung 2004 DW) ist ein großes transneptunisches Objekt im Kuipergürtel, das bahndynamisch als Plutino eingestuft wird. Aufgrund seiner Größe ist der Asteroid ein Zwergplanetenkandidat. Er hat einen bekannten Mond namens Vanth, der nach aktuellem Wissensstand etwa die Hälfte des Durchmessers des Mutterasteroiden aufweist. Daher kann dieses System auch als Doppelasteroidensystem verstanden werden.
