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.

12482 Pajka           Discovered 1997 Mar. 23 by A. Galád and A. Pravda at the Astronomical and Geophysical Observatory, Modra.
Paula Pravdová (b. 1990) is the only daughter of the second discoverer. She inherited many of her father's interests (playing musical instruments, cycling, swimming, diving, singing, joking) and that is why she was very popular when visiting Modra Observatory. Pajka is her familiar name.
