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.

| The research of Danish astrophysicist Anja C. Andersen (b. 1965) is an unusual combination of experimental, theoretical and observational work related to the properties and implications of dust particles. In 2005 she received the European Commission's Descartes Prize for outstanding excellence in science communication. |
