Named after Frederick John Marrion Stratton - British astronomer, astrophysicist (1881-1960).
Stratton is a lunar impact crater. It is located to the north of the large craters Keeler and Heaviside, and less than one crater diameter to the south of Dewar. As with many craters , this feature has become worn and eroded due to a multitude of subsequent impacts of various sizes. The most prominent of these is a small, cup-shaped impact along the southwestern outer rim. (wikipedia entry)
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.
