An explanation of the orbital elements is available. These orbital elements are also available in forms suitable for loading into a number of popular planetarium-type software programs. Ephemeris The following ephemeris is at intervals of five days. A daily ephemeris covering the same time interval is also available. Personalized ephemerides for this (and other) objects may be generated using the Minor Planet & Comet Ephemeris Service. Date TT R. A. (2000) Decl. Delta r Elong.
