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.

21523 GONG | Discovered 1998 June 26 by R. A. Tucker at the Goodricke-Pigott Observatory. |
The Global Oscillation Network Group operates solar telescopes in California, Hawaii, Australia, India, the Canary Islands and Chile that provide doppler, magnetic and intensity images every minute. Helioseismic data acquired at the GONG stations have provided much information about the interior structure of the sun. |
