Titania 

Titania, the largest moon of Uranus (788.9 kilometers in radius) was discovered by William Herschel in 1787. The moon is generally very rough, with many impact craters, rocks and impact basins. There is one long trench that extends 1,500 kilometers (1,000 miles) around the surface of the planet. The moon also is very internally active due to its plated surface and multiple faults.
