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.

4525 Johnbauer           Discovered 1982 May 15 by E. F. Helin, E. M. Shoemaker and P. D. Wilder at Palomar.
John Bauer (1932-2003), who taught astronomy and physics at San Diego City College for 37 years, dedicated his life, not to making discoveries himself, but to inspiring hundreds of students to pursue astronomical careers, helping them succeed and supporting their scientific goals. The name was suggested by N. Butler.
