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.

12583 Buckjean           Discovered 1999 Sept. 11 by D. K. Chesney at High Point.
Named for the discoverer's father, a railroad conductor, and his mother, a registered nurse. Both worked long hours to bring up their children, Gary, Dennis, Karen and Linda in Clovis, New Mexico. A Christmas gift of binoculars from his parents ultimately led to this discovery.
