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.

60150 Zacharias           Discovered 1999 Oct. 19 by P. Pravec and P. Kusnirak at Ondrejov.
Norbert (b. 1957) and Marion I. (b. 1960) Zacharias made important contributions to the link between the radio and optical reference frames and were instrumental in producing the US Naval Observatory's CCD Astrograph Catalog (UCAC) series of reference star catalogs widely used in the astronomical community.
