Cat #------Name----Certainty---Long---Lat-----Diameter---Radar Swath---------------------------------------------------------
None Momoy----- 2 -- 44.6W 11.6N--478 & 28 km-- T77
Is this a two-ring crater? The outer circle could be the edge of an ejecta deposit, but the fact that it stops and diverts the dunes coming from the west documents that it is a raised relief structure - a crater rim. The smaller inner rim is rounded. This concentric ring structure is unique on Titan.
Using radar foreshortening of opposing crater walls, Neish et al (2013) estimated the crater depth as 680 m +/-100 m. As I understand their paper, 680 m is the depth to the floor of the smaller crater; the rim height and crater depth of the outer ring are not known.
