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.

| 85559 Villecroze | Discovered 1998 Jan. 8 by S. Banh at the Dominion Astrophysical Observatory. |
| The discoverer is thankful for having completed her undergraduate degree in physics and astronomy, giving her the opportunity to work as a student at the DAO and then at the Canada-France-Hawaii telescope. It was in Hawaii that she met her husband Jean-Louis Villecroze, who is the most important person in her life. |
