Geology and Geophysics of Satellites and Small Bodies

Session ID#: 72863

Session Description:
This is a session of contributed and invited papers on the geology and geophysics of satellites and dwarf planets, including small exoplanets. Research is progressing rapidly due to the stream of new spacecraft and Earth-based telescope data.  Additionally, there are exciting future missions to the Jovian system under development.  Papers are welcomed on processes that affect the interiors of individual bodies as well as the surface expressions they produce. Included are the effects and chronology of internal heating (e.g., radioactivity, tidal dissipation), structural evolution (e.g., differentiation), tides, and other geophysical and geological processes (e.g., volcanism).
