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.

| 5134 Ebilson | Discovered 1990 Sept. 17 by H. E. Holt at Palomar. |
| Named in honor of Elizabeth M. Bilson (b. 1937), administrative director of the Center for Radiophysics and Space Research (CRSR), Cornell University. Raised in Hungary, Bilson studied at the Sorbonne and obtained her Ph.D. in chemistry from the University of Illinois at Champaign-Urbana. She was a research associate under Thomas Gold at the CRSR from 1969 to 1983, directing the Lunar Laboratory, and she has coauthored numerous articles related to the physical properties of lunar material, in particular explaining the reason for the low albedo of the moon. She is also a very a good cook. Name proposed by B. E. Clark, and citation written by M. Bilson. |
