Lagrange (Moon)

Named after Joseph Louis Lagrange - Italian mathematician (1736-1813).

Lagrange is a lunar crater that is attached to the northwestern rim of the crater Piazzi. It lies near the southwestern limb , and the appearance is oblong due to foreshortening. To the northwest of this feature is the Montes Cordillera, a ring-shaped mountain range that surrounds the immense Mare Orientale impact basin. The southwestern half of this walled plain has been heavily damaged by the mass of ejecta from Mare Orientale. (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.
