Uranus' moon Titania

Matt Williams

In fact, astronomers can now account for 27 moons in orbit around Uranus. Discovery and Naming: Titania was discovered by William Herschel on January 11th, 1787, the English astronomer who had discovered Uranus in 1781. 520 km (320 mi), which would mean the core accounts for 66% of the radius of the moon, and 58% of its mass. The surface of Titania is less heavily cratered than the surface of either Oberon or Umbriel, suggesting that its surface is much younger. These include craters, faults (or scarps) and what are known as grabens (sometimes called canyons).
