Short answers, pulled from the story.
William Herschel discovered the first two moons, Titania and Oberon, on the 11th of January 1787. William Lassell found Ariel and Umbriel in 1851, and Gerard Kuiper discovered Miranda in 1948 at the McDonald Observatory. Ten more inner moons were found during the Voyager 2 flyby in January 1986, and additional moons were identified through 2025 using the Subaru Telescope and the James Webb Space Telescope.
Uranus has 29 known moons as of 2025. They are divided into three groups: 14 inner moons, 5 major moons, and 10 irregular moons. The most recent addition, Uranus XXVIII, was announced in August 2025 from James Webb Space Telescope images taken in February 2025.
John Herschel, son of Uranus's discoverer, named the first four known moons in 1852 after magical spirits in English literature rather than figures from Greek mythology. He drew from William Shakespeare's A Midsummer Night's Dream and Alexander Pope's The Rape of the Lock. The International Astronomical Union continued this tradition, naming all subsequent Uranian moons after characters from Shakespeare's plays and Pope's poem.
Titania is the largest moon of Uranus, with a diameter of 1,578 km and a radius of 788.9 km. It is the eighth-largest moon in the Solar System, slightly larger than Rhea, the second-largest moon of Saturn.
Yes. Simulations show that Desdemona may collide with Cressida within the next million years, and Cupid is likely to collide with Belinda within ten million years. Perdita and Juliet may be involved in later collisions. The inner moon system is considered chaotic and apparently unstable.
Titania and Oberon may harbor liquid water oceans at the boundary between their rocky cores and ice mantles. All five major moons contain approximately equal amounts of rock and ice, except Miranda, which is made primarily of ice.
