The inner wall of the crater rim is multiply terraced in the northern half, while the southern rim has a shear inner surface leading down to slumped deposits on the crater floor. There is a small but prominent crater lying across the southwest rim, with an inner surface that forms terraced steps covering most of the interior. There are also smaller craterlets on the rim to the northeast and west-southwest.
The interior of Fizeau is relatively flat beyond the terraces, with only a few low rises in the northwest section of the crater and a central peak near the midpoint. Only a few tiny craterlets are located on the floor.
Satellite craters
By convention these features are identified on lunar maps by placing the letter on the side of the crater midpoint that is closest to Fizeau.
