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.

13390 Bouška           Discovered 1999 Mar. 18 by P. Pravec and M. Wolf at Ondřejov.
Jiří Bouška (b. 1925), emeritus professor of astronomy at Charles University, Prague, studied interplanetary matter and for 30 years served as the editor of the magazine Říše hvězd (The Realm of Stars) and the Czech Astronomical Yearbook. He taught several generations of Czech astronomers, including one of the discoverers.
