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.

2751 Campbell (1962 RP)          Discovered 1962-Sep-07 by Goethe Link Observatory at Brooklyn
Discovered by the Indiana Asteroid Program, Goethe Link Observatory, University of Indiana. This program was conceived and directed by F. K. Edmondson; the plates were blinked and measured astrometrically by B. Potter and, following her retirement, by D. Owings; and the photometry was performed under the direction of T. Gehrels. During the years 1947-1967, in which the plates were exposed, a large number of people participated in various aspects of the program.
