Planet masses and radii, versus composition models: Gray markers indicate planets with well-determined masses (errors smaller than 30%, from adopted values in the NASA Exoplanet Archive). Planets with periods of less than 2 days are shown with brown markers. Composition models indicated by solid lines are from Zeng et al. (2016, 2019), whereas the dashed line is a model from Dorn & Lichtenberg (2021) for an Earth-like rocky composition (66% Mg-Si oxides and silicates and 33% iron), where the molten rock contains water with a mass fraction of 5.4%. TOI-1416 b is indicated by the red dot.
