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.

10866 Peru           Discovered 1996 July 14 by E. W. Elst at the European Southern Observatory.
Peru, on the west coast of South America, is dominated by the great Andes mountain ranges, and it extends east to include the headwaters of the Amazon river. The country has been the home of several Andean civilisations, notably the Incas. Lake Titicaca on the southern border is the world's highest body of fresh water.
