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.

2193 Jackson           Discovered 1926 May 18 by H. E. Wood at Johannesburg.
Named in honor of Cyril Jackson, whose 67 discoveries of numbered minor planets constitute a record for the southern hemisphere. After working at the former Union Observatory in Johannesburg he was subsequently associated with the Yale-Columbia Southern Station at its successive locations. Name proposed by C. M. Bardwell and B. G. Marsden.
