. The smaller but prominent crater Cavalerius is joined to the northern rim by low ridges. Due south of Hevelius is the crater Lohrmann and the dark-hued Grimaldi. Only a low, eroded rim of Hevelius rises above the surface. The western wall is overlain by several small impacts. The flat floor of the crater has been flooded by

, and is now cross-crossed by a system of small clefts named the Rimae Hevelius. There is a low, one-km-high central peak offset to the northwest of the midpoint. The northeastern part of the interior is more irregular and contains a straight ridge running toward the southeast. Along the northwest floor, near the inner wall, is a small crater. This feature is sometimes referred to as Hevel, the astronomer's name in German (Hevelius is a Latinized form).

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 Hevelius.
