Descartes is a heavily-worn lunar crater that is located in the rugged south-central highlands of the Moon. To the southwest is the Abulfeda crater.
The rim of Descartes only survives in stretches, and is completely missing in the north. The crater 'Descartes A' lies across the southwest rim. The interior floor contains several curved ridges. These are concentric with the surviving outer walls to the northwest and southeast.
A section of the outer rim of Descartes is covered by a region that has a higher albedo than the surrounding surface. Measurements by the Clementine spacecraft showed that this patch is actually a magnetic anomaly—the strongest on the near side of the Moon. This magnetic field may be deflecting particles from the solar wind, and thus preventing the underlying surface from growing darker because of space weathering.
About 50 kilometers to the north of this crater was the landing site of the Apollo 16. The uneven region about the landing area is sometimes called the Descartes Highlands or the Descartes Mountains.
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 Descartes crater.
