The workshop examines how planetary masses constrain formation, dynamical history, internal structure, atmospheres and habitability. Lectures compare astrometry and precision radial velocities, their biases and complementary strengths, and use Gaia DR4 alongside long-running radial-velocity surveys to demonstrate joint orbital fitting. Hosted by the NASA Exoplanet Science Institute, the workshop offers in-person and remote attendance without a registration fee. It is aimed at advanced undergraduates, graduate students and postdoctoral researchers, while welcoming all career stages.
