This session primarily focuses on neutral atmospheres, surfaces, and exospheres of terrestrial bodies other than the Earth. This includes not only Venus and Mars, but also exoplanets with comparable envelopes, small bodies and satellites carrying dense atmospheres such as Titan, exospheres such as Ganymede, or with a surface directly exposed to space like asteroids. We welcome contributions dealing with processes affecting the atmospheres of these bodies, from the surface to the exosphere. We invite abstracts concerning observations, both from Earth or from space, modeling and theoretical studies, or laboratory work. Comparative planetology abstracts will be particularly appreciated.
