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.

2213 Meeus           Discovered 1935 Sept. 24 by E. Delporte at Uccle.
Named in honor of the Belgian amateur astronomer and professional meteorologist Jean Meeus, among whose numerous contrubutions to astronomy are the original 1963 edition of "Tables des Petites Planetes" and improved and updated versions of Oppolzer's canon of eclipses. His other writings range from dynamical studies of long-term motions of Apollo objects, through examinations of geometrical configurations of the planets, to the debunking of the idea that there exist observations of faint natural satellites of the earth. Name proposed by E. Bowell, who made the key identification for this planet, and also by J. U. Gunter, following a suggestion by E. Fogelin.
