Geological Chronicle
Hevelius is a low-rimmed lunar impact crater on the western edge of Oceanus Procellarum. Low ridges join its northern rim to the smaller but prominent crater Cavalerius, while the crater Lohrmann and dark-hued Grimaldi sit due south.
Lava flooded the flat floor of the crater, which is now cross-crossed by a system of small clefts named Rimae Hevelius. A low central peak rises one kilometer high, offset to the northwest of the midpoint. Near the inner wall on the northwest floor lies a small crater, while the more irregular northeastern interior contains a straight ridge running southeast.
Hevelius dates to the Nectarian age, with only a low, eroded rim rising above the surface. Several small impacts overlie its western wall. Named for the astronomer Johannes Hevelius by the IAU in 1935, the feature is also known as Hevel, the astronomer's name in German.
