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.

38238 Holíč           Discovered 1999 July 18 by Š. Gajdoš and D. Kalmančok at the Astronomical and Geophysical Observatory in Modra.
Dating from 1205 and first settled in the neolithic era, Holíč is in the Záhorie region of western Slovakia. Famous for its ceramics production in the eighteenth and nineteenth centuries, it is also known for its fortress that became the Habsburgs' summer residence. The town is the birthplace of the second discoverer.
