8 named features carry the IAU descriptor Catena — a chain of craters on Callisto, out of 59 in the mapped Solar System.
The IAU assigns each feature class on each world a naming theme. Across the 8 catenae with a recorded origin, one category covers them all, led by Norse.
Every one has its own page, on the surface it sits on.
The same descriptor is used on 6 other worlds, for 51 more features.
