We now know of thousands of exoplanet candidates discovered by NASA's Kepler Mission, using the so-called transit method. Unfortunately, transits only tell astronomers the size of the planet, not the mass. Cool Worlds Lab member Jingjing Chen discusses her new research paper which applies a type of forecasting model to predict planetary masses, based off their sizes. This reveals a couple of strange observations, as Jingjing explains in this video.
