For accurate long-term ephemerides, please instead use our Horizons system.This orbit viewer was implemented using two-body methods, and hence should not be used for determining accurate long-term trajectories (over several years or decades) or planetary encounter circumstances.

144907 Whitehorne | Discovered 2004 Dec. 16 by T. Glinos, D. Levy and W. Levy at Jarnac. |
Mary Lou Whitehorne, currently second vice-president of the Royal Astronomical Society of Canada, has devoted much of her life to educating young people in the basics of astronomy. Her original and interesting approach has led to a surge of interest in astronomy among young people throughout Canada. |
