Ramsay (Moon)

Named after Sir William Ramsay - British chemist; Nobel laureate (1852-1916).

Ramsay is a lunar impact crater that is located. It lies to the south-southwest of the larger crater Jules Verne, and is nearly in contact with the satellite crater Jules Verne P along the northern outer rim. To the southeast is the crater Koch, and to the west-southwest lies the overlapping pair of Roche and Pauli. This is a worn crater, although the rim retains a generally circular character and is marked only by tiny craterlets (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.
