Water geyser activity, cryovolcanism Water ! • • • 504 km 1.61 g/cc Likely source of material for Saturn’s E-ring Liquid water in crust/mantle of Enceladus Liquid heated by tidal flexure Young surface, apparently due to ice-water tectonics and volcanism Jovian Planets: Uranus Uranus ! Orbit: Diameter: Density: ! Spin axis is nearly perpendicular to its orbital plane ! ! • ! ! 19.2 AU 58,118 km 1.29 g/cc Likely a result of an ancient collision or near-miss Mostly a rock-ice interior, with only 15% H2 and trace He (bulk composition) Thick atmosphere of 83% hydrogen, 15% He and 2% methane Jovian Planets: Neptune Neptune ! ! ! ! ! Orbit: Diameter: Density: Nearly identical in composition to Uranus Strong storms sweep the outer cloud layers • ! 30.06 AU 49,532 km 1.29 g/cc Fastest winds in the solar system, up to 2000 km/hr Triton • • Moon of Neptune Location of N2 cryovolcanism, geyser activity...
