text: Oberon is the second largest and most massive of the Uranian moons after Titania, and the ninth most massive moon in the Solar System.[f] Oberon's density of 1.63 g/cm³, which is higher than the typical density of Saturn's satellites, indicates that it consists of roughly equal proportions of water ice and a dense non-ice component.
