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.

10950 Albertjansen           Discovered 1960 Sept. 24 by C. J. van Houten and I. van Houten-Groeneveld on Palomar Schmidt plates taken by T. Gehrels.
Albert Jansen (1940-2004), first director of The Hague Planetarium, was an exceptional teacher and talented experimenter. Living later in South Africa, he built a private observatory for use by advanced amateur astronomers. Shortly before his death he published Star Maps for Southern Africa, the first southern night-sky guide.
