Robertson (Moon)

Named after Howard Percy Robertson - American physicist, mathematician (1903-1961).

Robertson is an important lunar impact crater on the far side , just beyond the western limb. It lies just to the south of Berkner, a formation with a comparable size but more eroded features. Just to the east is Helberg, and to the southwest is Alter. The inner wall of the crater rim has a wide, complex formation of multiple terraces. (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.
