Uranus's+Satellites

Major Moons:


 * All large moons are relatively dark objects: their geometrical albedo varies in the range of 30–50%, while bond albedo is within the range of 10–23% Umbriel is the darkest moon, and Ariel is the brightest.**


 * The major moons of Uranus are believed to have formed in the accretion disc, which existed around Uranus for some time after its formation or resulted from the large impact suffered by Uranus early in its history.**


 * All major moons comprise approximately equal amounts rock and ice, except Miranda, which is made primarily of ice. The ice component may include ammonia and carbon dioxide. Their surfaces are heavily cratered, though all of them (except Umbriel) show signs of endogenic resurfacing in the form of lineaments (canyons) and, in the case of Miranda, ovoid race-track like structures called coronae.**


 * The largest Uranian moons may be internally differentiated, with rocky cores at their centers surrounded by ice mantles. Titania and Oberon may harbor liquid water oceans at the core/mantle boundary. The major moons of Uranus are airless bodies. For instance, Titania was shown to possess no atmosphere at a pressure larger than 10–20 nanobar.**

Miranda  Contains Silicate rock and organic compounds in it's interior with a water ice surface  Radius of 235.8km  Has Craters

 Ariel The moon's density is 1.66 g/cm3, which indicates that it consists of roughly equal parts water ice and a dense non-ice component. The latter could consist of rock and carbonaceous material including heavy organic compounds known as tholins. The presence of water ice is supported by infrared spectroscopic observations, which have revealed crystalline water ice on the surface of the moon.  Radius of 578.8km

 Umbriel  Same composition as Ariel  Radius of 584.7km

 Titania  One of the first two moons of Uranus to be discovered (January 11, 1787)  Radius of 778.9km  Made up of Carbon Dioxide, Nitrogen, and methane.

 Oberon One of the first two moons of Uranus to be discovered (January 11, 1787) and is the most heavily cratered on the surface Radius of 761.4km Made up of (assumedly) Carbon Dioxide, Nitrogen, and methane. (The precise composition is not known)
