Green (lunar crater)

Green is a lunar impact crater on the Moon's far side. It lies just to the west of the huge walled plain Mendeleev, and is nearly joined with the west-northwestern edge of the crater Hartmann.

The crater has not been significantly eroded although a few tiny craterlets lie along the edge and inner wall. The perimeter is nearly circular, but has an outward bulge along the eastern side with some indications of a landslip. The inner sides display some terrace structures, particularly to the northeast. At the midpoint of the relatively level interior floor is a central ridge. The floor is more level along the western half, with some low rises in the east. There are only a few tiny craterlets on the interior.

Prior to naming in 1970,^[1] this crater was known as Crater 216.^[2]

Satellite craters

By convention these features are identified on lunar maps by placing the letter on the side of the crater midpoint that is closest to Green.

Green M crater has a ray system and is consequently mapped as part of the Copernican system.^[3]
