Atlas (87 km) has steep wall and a distinct rim. Its floor is covered with a complex system of rilles, Rimae Atlas, which are quite clear at local Sunrise. The central peaks are small and there are only a handful of craterlets on the floor. Atlas forms a pair with neighbouring Hercules (69 km) to the west (left) in shadow.
