DescriptionOrcusandPlutoRotatingFrame.gif
The motion of Orcus and Pluto in a rotating frame with a period equal to Neptune's orbital period. (Neptune is held stationary.) Orcus is a plutino in a 2:3 mean motion resonance with Neptune. Pluto is grey and Orcus is red. Neptune is the white (stationary) dot at 5 o'clock. Uranus is blue, Saturn yellow, and Jupiter red. There are 41 frames each having 3*164.8 years (3 times Neptunes orbital period).
