CelestialObject.GetSpinRateAtEpoch(TimeSpan) Method

Top 

Description

Returns the instantaneous spin rate about the angular velocity vector. Note that a positive spin rate indicates a counter-clockwise rotation as viewed from the z-axis of the MJ2000 Earth Equator frame; a negative spin rate indicates a clockwise rotation as viewed from the z-axis of the MJ2000 Earth Equator frame, eg. for Venus.
