Habitability is the conformance of a residence or abode to the implied warranty of habitability. [ circular definition ] A residence that complies is said to be habitable . It is an implied warranty or contract, meaning it does not have to be an express contract , covenant , or provision of a contract .
Planetary habitability is the measure of a planet's or a natural satellite's potential to develop and maintain an environment hospitable to life. [1] Life may be generated directly on a planet or satellite endogenously.
The habitability of natural satellites is the potential of moons to provide habitats for life, though it is not an indicator that they harbor it. Natural satellites are expected to outnumber planets by a large margin and the study of their habitability is therefore important to astrobiology and the search for extraterrestrial life .
Surface planetary habitability is thought to require an orbit at the right distance from the host star for liquid surface water to be present, in addition to various geophysical and geodynamical aspects, atmospheric density, radiation type and intensity, and the host star's plasma environment.
Supergalactic habitable zone: a place in a supercluster of galaxies that can provide for habitability of planets. The supergalactic habitable zone takes into account events in galaxies that can end habitability not only in a galaxy, but all galaxies nearby, such as galaxies merging , active galactic nucleus , starburst galaxy , supermassive ...
Planetary habitability in the Solar System is the study that searches the possible existence of past or present extraterrestrial life in those celestial bodies. As exoplanets are too far away and can only be studied by indirect means, the celestial bodies in the Solar System allow for a much more detailed study: direct telescope observation, space probes, rovers and even human spaceflight.
The habitability potential is therefore in possible Earth-like exomoons and not in the planet itself. It was the first multiple-planet system to be found around a main-sequence star (as well as, consequently, an F star) and is shown to be dynamically stable in all scenarios.
