3 named features carry the IAU descriptor Catena — a chain of craters on Mercury, out of 59 in the mapped Solar System.
The IAU assigns each feature class on each world a naming theme. Across the 3 catenae with a recorded origin, 2 categories appear, led by American.
Every one has its own page, on the surface it sits on.
The same descriptor is used on 6 other worlds, for 56 more features.
