This session primarily focuses on neutral atmospheres and exospheres of terrestrial bodies other than Earth. This includes not only Venus and Mars, but also exoplanets with comparable envelopes, small bodies and satellites with dense atmospheres such as Titan, and exospheres such as Ganymede. 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, modelling and theoretical studies, or laboratory work. Comparative planetology abstracts will be particularly appreciated.

The session has historically prioritised contributions from early career scientists.
