90482 Orcus of death, and frequently acted as a guide of the deceased to the underworld. The absolute magnitude of Orcus is approximately 2.3 (comparable with the 2.6 of cubewano 50000 Quaoar). The detection of Orcus by the Spitzer Space Telescope in the far infrared and by Herschel Space Telescope in submillimeter constrains its diameter to . Orcus appears to have an albedo of about 21% to 25%, which may be typical of trans-Neptunian objects approaching the 1000 km diameter range. In the magnitude and size estimates reported above it was assumed that Orcus is a singular object. The presence of a
