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.

13154 Petermrva           Discovered 1995 Sept. 7 by A. Galád and A. Pravda at the Astronomical and Geophysical Observatory, Modra.
Peter Mrva (b. 1962) helped to build Modra observatory and was one of the first astronomers there. During years of mostly manual labor he taught, helped to explain and inspired the second discoverer in some areas, including astronomy and computer graphics.
