Uranus’ Moon Puck

Uranus’ moon Puck — 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).

In Celtic mythology and English folklore, Puck is a mischievous tricky sprite, originally an evil demon, but better known as a character in Shakespeare’s Midsummer Night’s Dream who travels around the globe at night with the fairies.

Most of the moons of Uranus are named after characters in Shakespeare or Alexander Pope.
