20 named features carry the IAU descriptor Catena — a chain of craters on The Moon, out of 59 in the mapped Solar System.
The IAU assigns each feature class on each world a naming theme. Across the 20 catenae with a recorded origin, 12 categories appear, led by Germany.
Every one has its own page, on the surface it sits on.
The same descriptor is used on 6 other worlds, for 39 more features.
