| Eponym | Pytheas |
Pytheas is a small Lunar impact crater located on the southern part of the Mare Imbrium, to the south of Lambert crater.
It has a sharply-defined rim, a hummocky outer rampart, and an irregular interior due to slumping or fall-back. There is a small crater along the northern outer rampart, and a similar crater about 20 km to the west. The crater possesses a small ray system that extends for a radius of about 50 kilometers. It is surrounded by lunar mare that is dusted with ray material from Copernicus crater to the south.

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 Pytheas crater.
