Petit (crater)
Petit is a small, bowl-shaped lunar impact crater that is located on the northwestern edge of the Mare Spumans. The crater has a prominent ray system. The name is appropriate, since Petit means small in French. But it was actually named in honor of Alexis Thérèse Petit, a French physicist. The crater lies to the south of the crater Townley, and east of Condon. Farther to the northwest is Apollonius. Petit was previously designated Apollonius W before being given a name by the IAU.
