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.

68853 Vaimaca           Discovered 2002 Apr. 19 at Los Molinos.
Vaimaca was one of the four "last charrás", native Uruguayan Indians sold by the state to a French manager to be exhibited in France in 1833. He had been an Indian chief who served as a soldier in the army of the Uruguayan national hero José Artigas. Vaimaca's mortal remains were repatriated from France to Uruguay in 2002.
