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.

24999 Hieronymus           Discovered 1998 July 24 by P. Pravec at Ondřejov.
Jerome van Aeken (Hieronymus Bosch, c. 1450-1516), was a Dutch painter of the late Middle Ages who showed the depths of the human mind. In works such as The Temptation of St. Anthony he used symbols to depict vulnerability to the temptation of evil and the obsessive attraction of lust, heresy and obscenity.
