Anaxagoras is a young lunar impact crater that is located near the north pole of the Moon. It lies across the larger and more heavily worn crater Goldschmidt. To the south-southeast is Epigenes, and due south is the worn remains of Birmingham.
Anaxagoras is a relatively recent impact crater that is young enough to still possess a ray system that has not been eroded by space weathering. The rays from the site reach a distance of over 900 kilometers from the rim, reaching Plato to the south. It is consequently mapped as part of the Copernican System.[1]
The crater interior has a relatively high albedo, making it a prominent feature when the Moon is nearly full. (The high latitude of the crater means that the Sun always remains close to the horizon even at maximum elevation less than a day after Full Moon.) The interior walls are steep and possess a system of terraces. The central peak is offset from the crater midpoint, and joins a low range across the crater floor. In fact, it appears that some of the central peak material has landed outside the crater rim.[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 Anaxagoras.
