Planetary habitability is the measure of a planet's or a natural satellite's potential to have as the existence of life beyond earth is unknown, planetary habitability is largely an extrapolation of k-type stars may be able to support life far longer than the sun low-mass planets are poor candidates for life for two reasons.
