Moon of Uranus · Updated May 2026
Titania.
Titania is the largest moon of Uranus at 1,578 km in diameter — about half the size of Earth's Moon. Its surface combines moderate cratering with huge fault systems and canyons, hinting at past tectonic activity, and the 2017 detection of a thin carbon dioxide atmosphere makes it one of the few moons with any detected gas envelope.

The Messina Chasmata canyon stretches 1,500 km across Titania's surface — about the distance from London to Athens.
About Titania
Named after the queen of the fairies in A Midsummer Night's Dream. Models suggest Titania may host a thin liquid water layer between its rocky core and icy mantle, kept liquid by ammonia antifreeze.
