Puck is one of the natural satellites of Uranus. It was discovered in 1985 by the Voyager 2 spacecraft during its flyby of the planet. Puck is the second-largest of Uranus' inner moons and is named after a character from William Shakespeare's play "A Midsummer Night's Dream." Puck has a somewhat irregular shape, measuring approximately 162 kilometers (around 100 miles) in diameter.
