HarkhebiHarkhebi is a large lunar crater of the category termed a walled plain. Half of the crater to the north-northwest is overlain by the walled plain Fabry, a large formation in its own right. Attached to the northwestern rim is the much smaller crater Vashakidze...

SzilardSzilard is a damaged lunar crater that lies to the east-northeast of the crater Richardson. It is named after Leo Szilard, the scientist who theorised nuclear chain reactions and famously worked on the atomic bomb during WWII. About a half-crater-diameter to the northwest is the large walled plain...

, which lies across the rim to the southwest. The northeastern rim of Maxwell reaches the approximate mid-point of Richardson, and together with the outer rampart covers nearly half the interior floor. The remainder of the rim of Richardson is worn and eroded, with Richardson W intruding into the northwestern rim and Richardson E lying along the eastern side.
The surviving interior floor of Richardson is relatively level, but marked with a number of small craterlets. The rim and interior floor is covered by a number of wispy deposits from the
Giordano BrunoGiordano Bruno is a 22 km lunar impact crater on the far side of the Moon, just beyond the northeastern limb. At this location it lies in an area that can be viewed during a favorable libration, although at such times the area is viewed from the side and not much detail can be seen...

By convention these features are identified on lunar maps by placing the letter on the side of the crater mid-point that is closest to Richardson.
