Four different ephemerides are available for Orcus using the standard astrological tropical zodiac. Pick the one which has the information you require.

Orcus has an elliptical orbit similar in shape and duration to Pluto. Those familiar with the movement of Pluto by transit will quickly understand the movement of Orcus. Note: all these ephemerides were extracted from the Riyal software.
