Spörer (Moon)

Named after Friedrich Wilhelm Gustav Spörer - German astronomer (1822-1895).

Spörer is a lunar crater that lies just to the north of the crater Herschel, and southeast of the lava-flooded Flammarion. To the southeast is Gyldén, and to the northeast is Réaumur. The floor of this crater has been flooded with basaltic lava, leaving only a shallow rim above the surface. The narrow rim is roughly circular but irregular and broken in several locations.

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.
