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.
