Lippmann (Moon)

Named after Gabriel Lippmann - French physicist; Nobel laureate (1845-1921).

Lippmann is a large lunar impact crater in the southern part of the far side and so cannot be viewed directly from the Earth. Just to the northeast is the walled plain Mendel, only slightly smaller than Lippmann. To the south-southeast lies the crater Petzval. As with many lunar formations of this size, Lippmann has been eroded by subsequent impacts. (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.
