Espin (Moon)

Named after Thomas Henry Espinall Compton - British astronomer (1858-1934).

Espin is a lunar crater that lies on the far side , just beyond the northeastern limb. It lies to the west-southwest of the larger crater Seyfert, and northwest of Deutsch. This is a worn formation with heavy damage along the northern rim. Several small craters lie along the northern edge, and a crater lies across the southern 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.
