Alden (crater)

Alden is a lunar crater that lies on the far side of the Moon, between Hilbert crater to the north-northwest and Milne crater to the south-southeast. To the south-southwest lies the Scaliger crater.

The Alden crater has a low rim that is overlain in the north and northeast by the 'Alden C' and smaller 'Alden E' craters. The rim is worn and eroded, with a low gap along the southern wall. The floor is somewhat irregular. Crater 'Alden V' lies just inside the north rim, and is attached to 'Alden C' to the east.

Satellite craters

By convention these features are identified on Lunar maps by placing the letter on the side of the crater mid-point that is closest to Alden crater.
