Chevallier (Moon)

Named after Temple Chevallier - British astronomer (1794-1873).

Chevallier is a lunar crater that is located in the northeastern part 's near side, about a crater diameter east-southeast of the prominent crater Atlas. To the south-southeast is the flooded crater Shuckburgh. This formation is little more than a disintegrated crater rim protruding upward slightly from a lava-flooded surface. All that survives of this feature is a few arcing sections of low ridges in the surface. (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.
