Gassendi crater (110 km.) shot: center-left, is located at the edge of Mare Humorum: plateau without landforms top center.
Gassendi was flooded by lava during the formation of Mare Humorum, so that only the rim and multiple peaks remained above the surface. Outer rim is eroded.. At the edge of the North (west photo) forms a pair of craters that has a likeness of a diamond ring. Crater Gassendi in some older maps is called Clarkson after British amateur astronomer and selenographer Roland Clarkson, but that name is not officially recognized by the IAU, and the name was "deleted".

The name comes from Pierre Gassendi (January 22, 1592 - October 24, 1655) a French philosopher, priest, scientist, astronomer and mathematician. With a high position in a church in south-eastern France, he spent also more time in Paris, where he was a leader of a group of free-thinking intellectuals. He was also an active scientist observational data by publishing the first transit of Mercury in 1631.

Mare Humorum ("Sea of Moisture") is an impact basin that is 389 km in diameter. An exact age has not been determined. However, geological mapping indicates an intermediate flows between basins Imbrium and Nectaris, resulting in about 3.9 billion years. Humorum basin is filled with a thick layer of basalt thickness exceeding 3 km in the center of the basin. At the northern edge of Mare Humorum, is crater Gassendi.
