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.

10581 Jeníkhollan           Discovered 1995 July 30 by P. Pravec at Ondřejov.
Jan (Jeník) Hollan (b. 1955), an astronomer and environmentalist at the Brno Observatory, has deeply influenced many students and observers, including the discoverer. Sometimes in unorthodox ways, he makes a point of teaching his students to examine the most substantial points.
