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.

| 10390 Lenka | Discovered 1997 Aug. 27 by P. Pravec and M. Wolf at Ondřejov. |
| Named in honor of Lenka Šarounová (b. 1973), an assiduous observer at the Ondřejov Observatory. She has a broad range of interests, from astronomy and meteorology to music. She loves gaining new experiences through traveling and meeting people. Her photometric and astrometric observations of minor planets became an integral part of the discoverers' research project on NEOs. |
