Below is a list of the IAU-accepted coordinate systems for the planets and satellites.
*Note: Targets defined as triaxial ellipsoids but which are treated
cartographically as spheres (as defined by the IAU).
Note: The IAU has a separate system for small bodies. Coordinates and systems for these targets will be updated when data are available.
Values used in these cartographic reference ellipsoids are from the Report of the IAU/IAG working group on cartographic coordinates and rotational elements.
