| Abstract | The majority of rocky planets that have both size and mass measured are much bigger than Earth, and studies suggest that an Earth-like composition may be common among them. However, the interior composition of truly Earth-sized planets remains largely unexplored. This proposal makes use of the newly-commissioned Keck Planet Finder (KPF) spectrograph to precisely measure the masses of 12 Earth-sized exoplanets whose size was already determined by transit measurements. These precise mass measureme |
