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.

18725 Atacama | Discovered 1998 May 2 by the OCA-DLR Asteroid Survey at Caussols. |
The Atacama desert, which covers regions II, III and IV of Chile, is one of the driest deserts on Earth. It contains many mineral resources, but also a number of very high-quality astronomical sites on which many modern instruments have been installed. |
