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.

| 12753 Povenmire | Discovered 1993 Apr. 18 by C. S. Shoemaker and E. M. Shoemaker at Palomar. |
| Katie Povenmire, a coronary critical care nurse, is a skilled observer of the skies with her husband Hal Povenmire. Meteor showers, lunar grazes and occultations for determining the diameters of minor planets come under her discerning eye. Katie understands well the joy and success of team work. |
