Chappell (crater)


Chappell is a lunar impact crater that is located on the far side of the Moon, in the northern hemisphere just to the north of the crater Debye. This feature is located in a heavily bombarded section of the surface, and much of the outer rim of the crater is overlain by many smaller craters. The northern rim in particular has been almost completely disintegrated, while small craters also overlie the rim to the northwest and southeast. What remains of the rim forms a rounded, somewhat irregular edge to the crater depression.
In contrast the interior floor is not notably marked by impacts except for a few tiny craterlets. The interior surface is more level and featureless compared to the rugged terrain that surrounds the crater. Near the midpoint of the floor is a low, rounded central ridge.

By convention these features are identified on lunar maps by placing the letter on the side of the crater midpoint that is closest to Chappell.
