Explore a fascinating conference talk examining how exoplanet discoveries inform our understanding of Earth's origins. Recorded during the "Planets on the Edge" conference at the Kavli Institute for Theoretical Physics (KITP), this 35-minute presentation by Lauren Weiss from Notre Dame investigates what thousands of short-period exoplanets discovered by Kepler, TESS, and ground-based telescopes reveal about planetary formation. Learn how these Earth-sized rocky planets, which have no direct counterparts in our Solar System, provide crucial insights into fundamental questions: the nature of close-in rocky planets and their atmospheres, whether they form in place or migrate inward, what parameters vary between star systems, and why similar planets don't exist around our Sun. This talk contributes to a broader scientific effort bringing together experts in exoplanet demographics, protoplanetary disks, planet formation models, and meteoritics to advance our understanding of Earth-sized planets in inner protoplanetary disks.
