Comparative study of the terrestrial planets provides critical constraints on Earth's formation and evolution that cannot be obtained from Earth's rock record alone. This session welcomes contributions that use studies of terrestrial planetary bodies to enhance understanding of planet Earth. We encourage contributions that address divergent evolutionary pathways across the terrestrial planets, as well as constrain a broad range of processes, such as core formation and differentiation, the effects of impact bombardment, habitability, the onset and sustainability of plate tectonics, atmospheric evolution, volcanic forcing, and controls on major components of the modern Earth system.
