Ariel is a fairy who was a servant of Prospero in William Shakespeare's play The Tempest.


Ariel is a moon of Uranus discovered in 1851 by William Lassell. Its composition is roughly 50% water ice, 30% silicate rock, and 20% methane ice, and it appears to have regions of fresh frost in places. Largely devoid of impact craters, Ariel appears to have undergone a period of intense geological activity that has produced a huge network of fault canyons and liquid water outflows over its surface.
