Moissan (Moon)

Named after Ferdinand Frederic Henri Moissan - French chemist; Nobel laureate (1852-1907).

Moiseev is a lunar impact crater that is located just on the far side. It lies to the south-southwest of the slightly larger crater Hertz, and north of Saenger. To the southeast lies the irregular crater Al-Khwarizmi. Moiseev overlies the southern rim of the larger satellite formation Moiseev Z. Moiseev is not significantly worn, and is marked only by a few tiny craterlets in the interior. (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.
