Planetary habitability

degree to which a planet is suitable for life, or study of planets which may be so suited

Planetary habitability is the measure of a planet's or a natural satellite's potential to develop and maintain environments that are hospitable to life.[1]

Understanding planetary habitability is partly an extrapolation of the conditions on Earth, as this is the only planet known to support life.
