The outer rim of Barbier has been eroded somewhat by subsequent impacts, particularly at the north end where the wall has been degraded by several small craterlets. A small crater lies across the eastern rim, and the southern rim is wider and irregular in shape. An unusual irregular crater (Barbier F) with a hummocky floor, approximately 16 km long, lies near where a central peak would be located, offset to the east of the midpoint.
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 Barbier.
