The rim of Gruithuisen is relatively smooth and circular, projecting only slightly above the surrounding
mare. The interior is relatively featureless with a small floor, with mounds of material deposited along the edges of the sloping inner walls.
To the north of the crater, along the edge of the highland peninsula between the two maria is a
domed mountainous rise that is designated
Mons Gruithuisen Gamma (γ). Just to the east of this feature is another mountainous rise named
Mons Gruithuisen Delta (δ). Northwest of Gruithuisen crater is concentrated cluster of several craterlets, which was most likely formed from a single body that broke up just prior to impact.
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 Gruithuisen.
