Named after Edgar Degas - French painter (1834-1917).
Degas is a rayed crater on Mercury at latitude 37.5, longitude 127. The rays consist of light colored material blasted out during the crater's formation. Craters older than Degas are covered by the ray material, while younger craters are seen superimposed on the rays. (wikipedia entry)
A crater is a circular depression likely created by an impact event. On Mercury they are named after deceased artists, musicians, painters, and authors who have made outstanding or fundamental contributions to their field and have been recognized as art historically significant figures for more than 50 years.
