Aston (Moon)

Named after Francis William Aston - British chemist, physicist; Nobel laureate (1877-1945).

Aston is a lunar impact crater that is located along the northwest limb. Because of its location the crater is seen nearly from on edge, and visibility is subject to libration. It lies to the east of the crater Röntgen, some distance due west of Ulugh Beigh on the edge of the Oceanus Procellarum. To the south is the crater Voskresenskiy. (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.
