List of catenae

In planetary geology, a catena (plural catenae) is a chain of impact craters or an alignment of depressions without raised edges, formed by the collapse of the basement or roof of a lava tube.

The [names in grey and italics] in the tables are dropped or moved, referenced here because they may appear in older documents. Latitudes and longitudes in white are planetocentric. Those in orange use the older planetographic system.
