Discovery of Titania

11 January 1787

Titania is the largest moon of Uranus, discovered by the astronomer William Herschel with his reflecting telescope at Slough in England, along with Oberon. It is about 1,580 kilometres in diameter, roughly half the size of Earth's Moon, and is made of a mixture of water ice and rock. The moons of Uranus are named after characters from the works of Shakespeare and Alexander Pope, and Titania, the queen of the fairies in A Midsummer Night's Dream, was named by Herschel's son John in 1852. In 1986 the spacecraft Voyager 2 flew past and showed a surface with craters and huge canyons, which suggest that it expanded as its interior froze.
