Puck is a moon of Uranus. It was discovered by Voyager 2 in 1986. Little is known about it aside from its orbit, its size, and its dark albedo (approximately 0.07).
Most of the moons of Uranus are named after characters in Shakespeare or Alexander Pope. In Celtic mythology and English folklore, a Puck is a mischievous sprite, imagined as an evil demon by Christians; the moon is named after the Puck who appears in Shakespeare's A Midsummer Night's Dream, where he travels around the globe at night with the fairies.
