Bettinus (crater)

Coordinates	63.4°S 44.8°W / -63.4; -44.8
Diameter	71 km
Depth	3.8 km
Colongitude	45° at sunrise
Eponym	Mario Bettinus

Bettinus is a lunar impact crater located near the southwest limb. Due to its location, the crater has a distinctly oval shape because of foreshortening. To the south of the rim is the similar-sized crater Kircher, and to the northwest is the slightly smaller Zucchius. From the west to the southwest, closer to the limb, is the giant formation Bailly.

The rim of Bettinus is only somewhat worn, with an inner wall that is wider to the northwest. The interior floor is relatively flat, with a central rise that is offset to the west of the mid-point. There is a small crater along the eastern rim.

Satellite craters

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 Bettinus.
