Edison (Moon)

Named after Thomas Alva Edison - American inventor (1847-1931).

Edison is a lunar crater on the far side. It is located just behind the north-northeastern limb , a region that is sometimes brought into sight from Earth during favorable librations. However even at such times not much detail can be discerned, and the crater is better observed by orbiting spacecraft. The Edison crater is attached to the southeastern outer rim of the crater Lomonosov, to the east of the walled plain Joliot. (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.
