Beyond the ruins of Dis are the frauds and corruptors, and finally the traitors. In ancient Roman mythology, Dis Pater ("Father Dis") is the ruler of the underworld and is named as such in the sixth book of Virgil's "Aeneid", one of the principal influences on Dante in his depiction of Hell (the god was also known as Pluto, a name not used by Virgil in the "Aeneid"). The hero Aeneas enters the "desolate
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
