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.

306128 Pipher | Discovered 2010 May 12 at WISE. |
Judith Pipher (b. 1940) is an astrophysicist and Emeritus Professor at the University of Rochester. One of the first U.S. astronomers to observe the skies with an infrared array camera, she is known as "the mother of infrared astronomy." She helped build and test infrared detectors for the Spitzer Space Telescope. |
