Palus Epidemiarum
The low rim of Hesiodus is heavily worn, with the southwest rim being slightly intruded upon by Hesodius A. The latter 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.
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 Hesiodus.
