The "Ice Giants" Uranus and Neptune are a different class of planet compared to Jupiter and Saturn. Studying these objects is important for furthering our understanding of the formation and evolution of the planets, and unravelling the fundamental physical and chemical processes in the Solar System. The importance of filling these gaps in our knowledge of the Solar System is particularly acute when trying to apply our understanding to the numerous planetary systems that have been discovered around other stars. This session welcomes all presentations on the planetary environments of Uranus and Neptune, as well as comparative planetology. Presentations based on new recent ground- or space-based observations, modelling, and future mission concepts will be included.
