Apianus (crater)

Apianus is a lunar impact crater that is located on the rugged south-central highlands of the Moon.

It is named after 16th century German mathematician and astronomer Petrus Apianus.

The outer wall of the crater has been worn and eroded by subsequent impacts, and a pair of small craterlets overlay the rim to the southeast and northeast.

The central crater is 63 kilometers in diameter and 2,080 meters deep.

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