Dis (Divine Comedy) in red-hot tombs. Beyond are rings of those who were violent—to others, to themselves (suicides), to God (blasphemers), to art (usurers), and to nature (sexual perverts). 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 with the normal object naming procedures. Vanth was found at 0.25 arcsec from Orcus with magnitude difference of . Estimates made in 2009 by Mike Brown show that the apparent magnitude of Vanth is which is magnitudes fainter than Orcus. Assuming equal albedos this would mean a diameter of 280 km, or 2.9 times smaller than the primary. However, the dissimilar colors of Orcus (neutral) and Vanth (red) suggest that Vanth could have an albedo a factor of two lower than Orcus. Should Vanth have an albedo of only 0.12, Vanth could be as large as 380 km with Orcus
