Eponym	Johannes Hevelius

Hevelius is a low-rimmed lunar crater that lies at the western edge of the Oceanus Procellarum lunar mare. The smaller but prominent crater Cavalerius is joined to the northern rim by low ridges. Due south of Hevelius is Lohrmann crater and the dark-hued Grimaldi basin.

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 lava, 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 mid-point. 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, a name that was used to refer to Johannes Hevelius.

[edit] Satellite craters

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 Hevelius crater.
