Margaret, also known as Uranus XXIII and previously as S/2003 U 3, is an irregular moon of Uranus. It is the only known irregular moon of Uranus that follows a prograde orbit, meaning it orbits in the same direction as the planet's orbit around the Sun. It was discovered by Scott S. Sheppard and David C. Jewitt at Mauna Kea Observatory on 29 August 2003, although it had been briefly observed earlier by Matthew J. Holman and JJ Kavelaars on 13 August 2001. The moon is formally named after Margaret, the servant of Hero in William Shakespeare's play Much Ado About Nothing, while also alluding to the discoverers' family members.
