Mean diameter: approximately 1,578 km · Orbits Uranus.
Titania is the largest moon of Uranus, although it is less than half the diameter of Earth’s Moon. Voyager 2 photographed both impact scars and long fault valleys, evidence that its crust has been stretched.
Those troughs distinguish it from a simple crater-covered sphere. Compare its fractured terrain with Oberon’s battered surface to see how two moons of one planet can preserve different geological histories.
