The exosphere is the only atmospheric layer ubiquitous in all terrestrial bodies. Their composition, energy, and density distribution can provide important insight into atmospheric photochemistry (Venus), atmospheric evolution timeline (Earth, Mars, Venus, Titan), surface composition via interactions with the Sun (Mercury, Earth and Jovian's moons), and space weather effects through coupling with the solar wind and the local plasma environment (Jovian moons, Earth, Mars, Titan). This session focuses on investigations of exospheres of terrestrial bodies throughout the solar system and other stellar systems (exoplanets). Topics for this session include physics- and data-based modeling of exospheres, remote sensing techniques including space- and ground-based UV and visible light observations, inversion methods to retrieve density distributions, the interaction of the neutral exospheres with local plasma population ( solar/stellar wind, plasmasphere, ionospheres), estimations of atmospheric escape rates (due to planetary orbital location and solar/stellar activity), and presentations of current/upcoming missions aimed for exospheric observations.
