1,237 named features carry the IAU descriptor Crater — a circular depression, almost always an impact scar on Mars, out of 4,787 in the mapped Solar System.
The IAU assigns each feature class on each world a naming theme. Across the 1,237 craters with a recorded origin, 221 categories appear, led by United States.
Every one has its own page, on the surface it sits on.
997 smaller craters are not listed here. The full Mars gazetteer has every one.
The same descriptor is used on 12 other worlds, for 3,550 more features.
