Planetary Satellite Ephemerides

The following tables list the current JPL planetary satellite ephemeris used for each planetary satellite. These ephemerides are used by Horizons to provide high-precision ephemerides for the planetary satellites. Tables are grouped by planet (and category of satellite for planets with many satellites).
