Eponym	Jean Dufay

Dufay is a lunar crater that is located on the far side of the Moon. It lies about one crater diameter to the east of the large walled plain Mandel'shtam. To the northwest is the crater Papaleksi and to the east is Valier.

The rim of this crater is heavily worn by impacts, and several small craterlets lie along the southern edge. The inner wall is somewhat wider on the western side when compared to the east and southeast. The interior floor is relatively level and featureless.

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 Dufay.
