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.

9931 Herbhauptman           Discovered 1985 Apr. 18 by A. Mrkos at Klet.
Renowned mathematician Herbert A. Hauptman (b. 1917), since 1986 president of the Hauptman-Woodward Medical Research Institute in Buffalo, New York, shared the 1985 Nobel prize in chemistry for his development of a mathematical model to determine the crystal structure of complex molecules from x-ray diffraction.
