Bettinus (Moon)

Named after Mario Bettinus - Italian mathematician, astronomer (1582-1657).

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.

A crater is a circular depression likely created by an impact event. On the Moon they are named after deceased scientists, polar explorers, astronauts or cosmonauts.
