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.

136666 Seidel           Discovered 1995 Sept. 17 by M. Tichy and J. Ticha at Klet.
The work of Cesky Krumlov photographers Josef Seidel (1859-1935) and his son František (1908-1997) depicts both people and places of the southeast part of Sumava. The preserved archive of negatives opens a window into the first half of the 20th century, including Czech-German connections.
