List of craters on Mercury

[3][4][5][a] Other, non-planetary bodies with numerous named craters include Callisto (141), Ganymede (131), Rhea (128), Vesta (90), Ceres (90), Dione (73), Iapetus (58), Enceladus (53), Tethys (50) and Europa (41).

As on the Moon and Mars, sequences of craters and basins of differing relative ages provide the best means of establishing stratigraphic order on Mercury.

Over all of Mercury, the crispness of crater rims and the morphology of their walls, central peaks, ejecta deposits, and secondary-crater fields have undergone systematic changes with time.

The oldest craters consist only of shallow depressions with slightly raised, rounded rims, some incomplete.

On this basis, five age categories of craters and basins have been mapped; the characteristics of each are listed in the explanation.
