Origin and evolution Titania is thought to have formed from an accretion disc or subnebula; a disc of gas and dust that either existed around Uranus for some time after its formation or was created by the giant impact that most likely gave Uranus its large obliquity . [31] The precise composition of the subnebula is not known; however, the relatively high density of Titania and other Uranian moons compared to the moons of Saturn indicates that it may have been relatively water-poor. [j] [6] Significant amounts of nitrogen and carbon may have been present in the form of carbon monoxide and N 2 instead of ammonia and methane. [31] The moons that formed in such a subnebula would contain less water ice (with CO and N 2 trapped as a clathrate) and more rock, explaining the higher density. [6] Titania's accretion probably lasted for several thousand years. [31] The impacts that accompanied accretion caused heating of the moon's outer layer.
