About Uranus's Moon System

Uranus has 28 known moons, all named after characters from the works of William Shakespeare and Alexander Pope. The five major moons -- Miranda, Ariel, Umbriel, Titania, and Oberon -- were all discovered before the Space Age. Miranda, the smallest of the major moons at 472 km in diameter, has one of the most bizarre surfaces in the solar system, featuring a patchwork of old, heavily cratered terrain alongside younger, grooved regions with cliffs up to 20 km high. Titania and Oberon are the largest, with diameters of 1,578 km and 1,523 km respectively. The moon system of Uranus is relatively compact compared to the systems of Jupiter and Saturn, with all major moons orbiting within 583,000 km of the planet. Like Uranus itself, the moons orbit in a plane tilted nearly 98 degrees.
