The interaction between the solar wind and a planet with an appreciable intrinsic magnetic field leads to a planetary magnetosphere. There are significant differences between the magnetospheres in our solar system. Studying these diverse systems is important for understanding the complex interaction between the Sun and a magnetised planet, and is relevant for the study of exoplanetary magnetospheres. In this session we invite submissions covering the configuration and dynamics of plasma and magnetic fields in all non-terrestrial solar system magnetospheres (Mercury, Jupiter, Saturn, Uranus, and Neptune). The magnetospheric physics sub-topics covered include, but are not limited to, solar wind-magnetosphere interactions, transport of magnetospheric plasma, magnetotail processes, and rotational dynamics. We particularly encourage submissions that compare magnetospheres, including comparison with the more extensively studied terrestrial magnetosphere. The session will be an ideal forum for the discussion of recent advances in our understanding of all these systems, relevant for a number of current and future missions.
