Titania
1,600 kmdiameter
Details
Titania is Uranus' largest moon, about 1,600 kilometers across. Voyager 2 saw long fault valleys and other signs of crustal extension, evidence that its icy crust stretched and cracked.
Voyager 2 imaged long fault valleys crossing Titania, evidence that the icy crust expanded and fractured after the oldest terrain formed. Bright deposits on some sun-facing valley walls may be frost. Models informed by Voyager data also allow a briny ocean beneath the ice, but Titania has not been revisited closely enough to confirm it.

About
Scale of Space is a scroll-based journey through the universe, placing objects on a single logarithmic scale so you can compare size across an unbroken range.
Guides explain selected parts of that range, while focused views filter the objects by subject.
