Titania is Uranus’ largest moon. Images taken by Voyager 2 almost 200 years after Titania’s discovery revealed signs that the moon was geologically active.
A prominent system of fault valleys, some nearly 1,000 miles long, is visible near the terminator (shadow line). The troughs break the crust in two directions, an indication of some tectonic extension of Titania’s crust. Deposits of highly reflective material, which may represent frost, can be seen along the sun-facing valley walls.
The moon is about 1,600 km (1,000 miles) in diameter. The neutral gray color of Titania is typical of most of the significant Uranian moons.
Titania was discovered on 11 January 1787 by British astronomer William Herschel.

PLANETARY FORMATION EVIDENT
“With a diameter of 1.610 kilometers, Titania is the largest satellite of Uranus. Like Oberon, much of its surface is heavily cratered and includes multiring impact basins. Titania has more faults than Oberon, including features 20 to 50 kilometers wide that appear to be grabens. High-albedo materials – possibly ice of frost deposits – are exposed on some of the cliff faces. The faults may represent global extension of Titania’s crust, perhaps in response to expansion that occurred as ice froze in the interior of the satellite. Smooth, relatively uncratered zones look like areas that have been resurfaced by the extrusion of fluid-like materials, such as ice slush.”
