Hesiodus (crater)
Encyclopedia
Hesiodus is a lunar impact crater
located on the southern fringes of Mare Nubium
, to the northwest of the crater Pitatus
. Starting near the northwest rim of Hesiodus is the wide cleft named Rima Hesiodus. This rille
runs 300 km east-southeastward to the Palus Epidemiarum
The low rim of Hesiodus is heavily worn, with the southwest rim being slightly intruded upon by Hesodius A. The later is an unusual circular crater with a concentric inner wall. To the southeast, a cleft in the wall of Hesiodus joins the crater to Pitatus.
Inside Hesiodus, the floor is flooded and relatively flat. It lacks a central peak, and, instead, a small impact crater Hesiodus D lies at the middle.
Impact crater
In the broadest sense, the term impact crater can be applied to any depression, natural or manmade, resulting from the high velocity impact of a projectile with a larger body...

Mare Nubium
Mare Nubium is a lunar mare in the Nubium basin on the Moon's near side. The mare is located just to the southeast of Oceanus Procellarum. The actual basin is believed to be of Pre-Nectarian system, with the surrounding basin material being of the Lower Imbrian epoch. The mare material is of the...

Pitatus (crater)
Pitatus is an ancient lunar impact crater located at the southern edge of Mare Nubium. Joined to the northwest rim is the crater Hesiodus, and the two are joined by a narrow cleft. To the south lie the attached Wurzelbauer and Gauricus....
