  2. Planetary habitability - Wikipedia

    en.wikipedia.org/wiki/Planetary_habitability

    Although geologically active planets with volcanism but no plate tectonics, called Ignan Earths, could also be habitable. [50] "Low mass" is partly a relative label: the Earth is low mass when compared to the Solar System's gas giants, but it is the largest, by diameter and mass, and the densest of all terrestrial bodies.

  3. 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.

    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 ...

    The planet is about the size of Venus, so slightly smaller than Earth, and may be temperate enough to support life, the researchers said. Dubbed Gliese 12 b, the planet takes 12.8 days to orbit a ...

    Two teams of scientists have discovered a theoretically habitable planet called Gliese 12b that’s smaller than Earth but bigger than Venus, just 40 light-years away.

  7. Superhabitable world - Wikipedia

    en.wikipedia.org/wiki/Superhabitable_world

    Due to the low luminosity of red dwarfs, the circumstellar habitable zone (HZ) [a] is in very close proximity to the star, which causes any planet to become tidally locked. [14] The primary concern for researchers, however, is the star's propensity for frequent outbreaks of high-energy radiation , especially early in its life, that could strip ...

  8. Habitability of red dwarf systems - Wikipedia

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

    The low masses of red dwarves (from roughly 0.08 to 0.60 solar masses (M ☉)) cause their nuclear fusion reactions to proceed exceedingly slowly, giving them low luminosities ranging from 10% to just 0.0125% that of the Earth's Sun. [20] Consequently, any planet orbiting a red dwarf would need a low semi-major axis in order to maintain an ...
