The advent of radial velocity (RV) and transit photometry method has resulted in the detection of more than 5000 exoplanets since 1995. Of these detected planets, a significant fraction, ∼20%,1 may be dominantly rocky. Given the biases inherent to exoplanet detection, this implies an even larger fraction of the overall planet population as likely possessing a significant rock fraction (e.g., Fulton et al. 2017). However, owing to the difficulty in detecting Earth-sized planets, the vast majority of these rocky planets are much larger than Earth (so-called ‘super-Earths’); with radii ≲ 1.5 times that of Earth (1.5 RE...
