Surface gravity and effective temperature of the hosts of transiting giant planets (similar to an H–R diagram). The position of HD 202772A (red) falls near the edge of the occupied region of parameter space. The solid gray line is the best-fitting MIST stellar mass track of 1.721 ﹩{M}_{\odot }﹩. We estimate that the stellar age is 1.71 Gyr, and that it is going to leave its main-sequence life in ∼0.5 Gyr. Data were obtained from the NASA Exoplanet Archive (Akeson et al. 2013) on 2018 September 15.
