Session Proposal: Planetary Impacts as a Fundamental Geophysical Process: Multidisciplinary Perspectives (AGU25)

P029
Planetary Impacts as a Fundamental Geophysical Process: Multidisciplinary Perspectives

Session ID#: 258535

Session Description:
Encounters between planetary bodies may result in collisions: high-energy events whose outcomes range from cratering to catastrophic destruction. Impact processes can have fundamental effects on the geophysical properties, interior structure, and the formation and evolution of planetary bodies. We solicit interdisciplinary and integrated presentations covering aspects of planetary impact processes both in solar-system and extrasolar system contexts. Welcome topics include, but are not limited to, collisional processes in protoplanetary disks, formation of planetesimals and asteroid families, giant impacts, cratering impacts, and effects of impacts on planetary surfaces and atmospheres. We encourage presentations that advance our understanding of impact processes from different perspectives, including observations from spacecraft and Earth-bound telescopes, modeling, theory, and experiments both in the laboratory and in space. We will emphasize contributions that integrate modeling, observations, and experimental studies that advance our understanding of the timing, mechanisms, and consequences of impact-related processes.
