This is a list of named craters on Mercury, the innermost planet of the Solar System (for other features, see list of geological features on Mercury).[2] Most Mercurian craters are named after famous writers, artists and composers. According to the rules by IAU's Working Group for Planetary System Nomenclature, all new craters must be named after an artist that was famous for more than fifty years, and dead for more than three years, before the date they are named.[6] Craters larger than 250 km in diameter are referred to as "basins" (also see § Terminology).[7][8]
As of 2021, there are 414 named Mercurian craters,[2] a small fraction of the total number of named Solar System craters, most of which are lunar, Martian and Venerian craters.[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). For a full list, see List of craters in the Solar System.
