Physical features
With a radius of 2.72 times that of Earth, it is likely a mini-Neptune with a gaseous composition. Assuming that Kepler-445c instead has the same density as Earth, it would have a mass of 15.9 MEarth, according to the PHL exoplanet density calculator Archived 2017-08-24 at the Wayback Machine.
