Physical Features

Size comparison

Earth	Kepler-445c

With a radius of 2.5R⊕ it is likely a Water world or even a Mini-Neptune if gaseous. Due to its high radius it would have to have a mass of 15.9M⊕ According to the PHL exoplanet density calculator to have a density similar of that of the Earth.
