The rim of Protagoras is circular and rises above the surrounding flat terrain, although the rim dips down along the southwestern edge. The interior floor contains a few light markings but no formations of interest. There is an area of rough terrain just to the east of this crater, but the surroundings are otherwise level with only a few small craters in the vicinity.
The crater is named for the Greek sophist Protagoras of Abdera.
Protagoras is a crater of Lower (Early) Imbrian age.[1]
