Anaxagoras is a young lunar impact crater that is located near the north pole of the Moon.
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.
[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.)
[2] 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.
