The solar system terrestrial planets, and especially the Earth, provide the best opportunity to learn about the basic physical principles of rocky planets, which can then be applied to the evolution of exoplanets and their atmospheres. Similarly, knowledge of the diversity and properties of exoplanetary systems can provide important information about the formation and evolution of our own solar system. In this session, we will focus on general discussions of exoplanetary science, and especially the application of solar system based knowledge to exoplanets and understanding how the Earth can be understood in the exoplanetary context. Of particular interest are studies of atmospheric evolution due to surface-atmosphere interactions and atmospheric losses to space, as well as interactions between stars and planets. Topics include recent advances in observations of (exo)planets lying in the habitable zone, model studies calculating the habitable zone boundaries, factors affecting habitability including atmospheric processes (e.g. outgassing, escape), high energy particles, remote biosignatures and their spectra, planned missions such as JWST, PLATO, E-ELT, LUVOIR, HABEX and ELF and their impact on our knowledge of exoplanetary habitability.
