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.

7114 Weinek           Discovered 1986 Nov. 29 by A. Mrkos at Klet.
Ladislaus Weinek (1848-1913), the ninth director of the Klementinum observatory in Prague, collaborated with Küstner in the discovery of polar motion. He published a lunar atlas based on photographs from the Lick Observatory. The name was suggested by J. Ticha and M. Šolc.
