  2. List of potentially habitable exoplanets - Wikipedia

    en.wikipedia.org/wiki/List_of_potentially...

    This is a list of confirmed exoplanets within the circumstellar habitable zone that are either under 10 Earth masses or smaller than 2.5 Earth radii, and thus have a chance of being rocky. [ 3 ] [ 1 ] Note that inclusion on this list does not guarantee habitability, and in particular the larger planets are more unlikely to have a rocky ...

  3. Planetary habitability - Wikipedia

    en.wikipedia.org/wiki/Planetary_habitability

    Understanding planetary habitability is partly an extrapolation of the conditions on Earth, as this is the only planet known to support life.. Planetary habitability is the measure of a planet's or a natural satellite's potential to develop and sustain an environment hospitable to life. [1]

  4. Habitability of natural satellites - Wikipedia

    en.wikipedia.org/wiki/Habitability_of_natural...

    To support an Earth-like atmosphere for about 4.6 billion years (Earth's current age), a moon with a Mars-like density is estimated to need at least 7% of Earth's mass. [20] One way to decrease loss from sputtering is for the moon to have a strong magnetic field of its own that can deflect stellar wind and radiation belts.

  6. Habitability of red dwarf systems - Wikipedia

    en.wikipedia.org/wiki/Habitability_of_red_dwarf...

    Red dwarfs [12] are the smallest, coolest, and most common type of star. Estimates of their abundance range from 70% of stars in spiral galaxies to more than 90% of all stars in elliptical galaxies, [13] [14] an often quoted median figure being 72–76% of the stars in the Milky Way (known since the 1990s from radio telescopic observation to be a barred spiral). [15]

  7. Planetary habitability in the Solar System - Wikipedia

    en.wikipedia.org/wiki/Planetary_habitability_in...

    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.

  8. List of nearest terrestrial exoplanet candidates - Wikipedia

    en.wikipedia.org/wiki/List_of_nearest...

    This list is incomplete, currently containing 34 exoplanets, 11 of which probably lie inside their star's habitable zone. There are roughly 2,000 stars at a distance of up to 50 light-years from the Solar System [4] (64 of them are yellow-orange "G" stars like the Sun [5]). As many as 15% of them could have Earth-sized planets in the habitable ...

  9. Superhabitable world - Wikipedia

    en.wikipedia.org/wiki/Superhabitable_world

    Thus, F-type stars are described as the "hot limit" for stars that can potentially support life, as their lifespan of 2 to 4 billion years would be sufficient for habitability. [10] However, F-type stars emit large amounts of ultraviolet radiation , and without the presence of a protective ozone layer, could disrupt nucleic acid-based life on a ...
