Nasreddin (crater)
Nasreddin is a crater on Pluto's largest moon, Charon. The crater was first observed by NASA's New Horizons space probe on its flyby of Pluto in 2015. The name was chosen as a reference to Nasreddin, the hero of humorous folktales told throughout the Middle East, southern Europe and parts of Asia.
The location of Nasreddin crater is in the northern Pluto-facing hemisphere of Charon, north of Mandjet Chasma in a region informally called Oz Terra. The crater has bright bluish rays, which have exposed ammonia and water ice.
