Beautiful ring-shaped crater in these pictures is called Gassendi (110 km), and is situated on the northern  Mare Humorum basin. "Jewel" of the ring is Gassendi A (33 km), a satellite crater that can be found in some older maps as Clarkson, named after the selenographer Roland Clarkson, but this name was not accepted.

Most interesting on Gassendi, inside it is full of rilles that stretch across the entire floor in several directions. Also on the floor, we see another circular inner wall.

Although this is a huge crater 110 km in diameter, it has a depth of only 1.9 km.
