Outer planet magnetospheres are different from the terrestrial one mainly because of their rapid rotation, unique sources of plasma and neutrals (e.g., Io and Enceladus), and their distance from the sun, reducing its influence. This session invites abstracts on the structure, dynamics, and variability of the magnetospheres of the giant planets (Jupiter, Saturn, Uranus, Neptune) and Ganymede, spanning in situ and remote observations, theory and modeling. Subjects that are welcome include magnetosphere-ionosphere coupling, aurora, especially outside of the visible wavelengths, radiation, satellite and ring surface constituents and weathering, neutrals and dust. The session will provide a forum for discussion of recent advances enabled by spacecraft and ground-based observations alongside numerical modeling efforts, and will highlight emerging opportunities and open questions motivated by ongoing and upcoming exploration of the outer planet magnetospheres.
