Outer planets are complex systems comprising not only the exciting atmospheres and interiors of the giant planets but also unique satellites and rings. This session encompases the outer planets systems in a general sense, including the gas giants, their ring systems and their satellites. In particular, Ganymede is the only satellite that possesses an internal dynamo. Europa’s ocean has significant astrobiological potential and the ocean/rock interface might resemble the terrestrial sea floor. Around Saturn, Titan is the only moon in the solar system with a dense atmosphere and the only place besides earth with stable liquids at its surface. Enceladus ejects water vapor and organics from its south pole. Io’s volcanoes bear a lot of similarities with those of Earth, but at much higher levels of activity and many of the satellites exhibit stunning variety in tectonic processes. This session will cover the atmospheres, surfaces, interiors and exchange processes in the outer solar system, including Pluto and Charon. The session welcomes abstracts describing observations, laboratory experiments and numerical simulations.
