90482 Orcus given the designation S/2005 (90482) 1 before later being named "Vanth". It orbits Orcus in a nearly face-on circular orbit with an eccentricity of about 0.007, and an orbital period of 9.54 days. Vanth orbits only from Orcus and is too close to Orcus for ground-based spectroscopy to determine the surface composition of the satellite. Mike Brown suspects that like the Pluto–Charon system, Orcus and Vanth are tidally locked. Vanth does not resemble known collisional satellites because its spectrum is very different from that of its primary, and it may be a captured KBO. Vanth could also have originated as
Cupid and Psyche to throw herself off. The tower, however, suddenly breaks into speech, and advises her to travel to Lacedaemon, Greece, and to seek out the place called Taenarus, where she will find the entrance to the underworld. The tower offers instructions for navigating the underworld: The airway of Dis is there, and through the yawning gates the pathless route is revealed.
