Titania is the largest of Uranus’ moons, though Oberon is very close to it in size.  Titania’s surface is somewhat similar to, though apparently a little older than, the surface of Ariel.  It has many small, but few large, craters, as well as networks of interconnected valleys.  There is one multi-ringed basin of about 300 kilometers in diameter, named Gertrude, near the moon’s equator.
