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.

5061 McIntosh           Discovered 1988 Feb. 22 by R. H. McNaught at Siding Spring.
Bruce A. McIntosh (b. 1929) worked at the National Research Council Canada. The radar meteor survey work he carried out with Peter Millman remains a benchmark. The Czech Academy of Science awarded him a special gold medal for fostering cooperative research on meteors. The name was suggested by C. Keay.
