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.

38674 Těšínsko           Discovered 2000 Aug. 9 by L. Šarounová at Ondřejov.
Těšínsko is a region in the southeastern part of Silesia, where the Olza river traverses. In the thirteenth century the region became a principality. After the breakdown of the Austrian-Hungarian Empire the region was split between the newly created states of Czechoslovakia and Poland in 1920.
