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.

11916 Wiesloch           Discovered 1992 Sept. 24 by L. D. Schmadel and F. Borngen at Tautenburg.
The city of Wiesloch celebrates the 1200th anniversary of its first documented mention in mid-2001. Situated some 16 km south of the famous Heidelberg-Königstuhl Observatory, it became the home town of the first discoverer more than 30 years ago.
