Domovoy is the second-largest known crater on Uranus's Ariel's surface, with a diameter of 71 km. The name comes from Domovoy, a spirit that protects homes in Slavic mythology; this name was approved by the International Astronomical Union in 1988. It was imaged for the first time by the Voyager 2 spacecraft in its January 1986 flyby of the Uranian system.
