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.

25942 Walborn | Discovered 2001 Mar. 2 by the Lowell Observatory Near-Earth Object Search at the Anderson Mesa Station. |
Nolan R. Walborn (b. 1945) is a stellar spectroscopist specializing in the optical and ultraviolet morphology of hot, massive stars, such as O and B, Wolf-Rayet, and Luminous Blue Variables. His studies have included star forming regions in the Milky Way and the Magellanic Clouds. |
