Orcus in 3D — live position and orbit

Sometimes nicknamed the "anti-Pluto" for an orbit that mirrors Pluto's own 2:3 resonance with Neptune, timed so the two are never close together. Its large moon Vanth may be tidally locked to it, much like Charon is to Pluto.

Orcus is shown at its real position, computed from NASA/JPL ephemeris data. The view opens on Orcus; you can travel in time, switch between the educational overview and the true-scale voyage, and compare it with every other body of the solar system.
