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.

| 18581 Batllo | Discovered 1997 Dec. 7 by the OCA-DLR Asteroid Survey at Caussols. |
| Valerie Batllo (b. 1967) works on cometary orbits at the Institut de Mécanique Céleste in Paris. She studies in particular how the short-period comets could be produced by encounters with the giant planets. |
