Oberon ("OH ber on) is the outermost of the major moons of the planet Uranus. It was discovered on January 11, 1787 by William Herschel.
The name "Oberon" and the names of all four satellites of Uranus then known were suggested by Herschel's son John Herschel in 1852 at the request of William Lassell, who had discovered Ariel and Umbriel the year before.[1] Lassell had earlier endorsed Herschel's 1847 naming scheme for the seven then-known satellites of Saturn and had named his newly-discovered eighth satellite Hyperion in accordance with Herschel's naming scheme in 1848.
All of the moons of Uranus are named for characters from Shakespeare or Alexander Pope. Oberon was named after Oberon, the king of the Faeries in A Midsummer Night's Dream.
