Planetary Satellite Ephemerides

The following table lists JPL planetary ephemeris files. Files are available in SPK format for use with the NAIF Spice toolkit. Additional ephemeris file and files covering different time spans are available from the NAIF website. These ephemerides are used by Horizons to provide high-precision ephemerides for the planetary satellites.
