  2. Habitable zone - Wikipedia

    en.wikipedia.org/wiki/Habitable_zone

    As the name suggests, the continuously habitable zone is a region around a star in which planetary-mass bodies can sustain liquid water for a given period. Like the general circumstellar habitable zone, the continuously habitable zone of a star is divided into a conservative and extended region. [91]

    The super-Earth HD 40307 g around the K2.5V star HD 40307 orbits in the circumstellar habitable zone (CHZ), although it has a reasonably elliptical orbit (e=0.22). There may be many more, and the Kepler space telescope (now retired) was one of the main sources of information of these exoplanets. [9]

  4. Habitability of neutron star systems - Wikipedia

    en.wikipedia.org/wiki/Habitability_of_neutron...

    The habitability of neutron star systems is the potential of planets and moons orbiting a neutron star to provide suitable habitats for life. [1] Of the roughly 3000 neutron stars known, only a handful have sub-stellar companions. The most famous of these are the low-mass planets around the millisecond pulsar PSR B1257+12.

  5. Small rocky planet detected in orbit about nearby Barnard's star

    Because of this, scientists eager to study nearby potentially habitable worlds are excited by the discovery of the first confirmed planet orbiting Barnard's star, a rocky one with a mass about 40% ...

  6. Habitability of F-type main-sequence star systems - Wikipedia

    In addition, hotter stars would have wider habitable zones (2.0–3.7 AU for an F0 star and 1.1–2.2 AU for an F8 star as opposed to 0.8–1.7 AU for the Solar System), which would be another advantage of looking for habitable planets around F- and A-type stars. [2]

    Scientists refer to a "habitable zone" around a star - a distance considered not too close and not too far from it for a rocky planet to be able to host life. Earth resides within the sun's ...

    Upcoming missions such as the European Space Agency’s PLATO, or PLAnetary Transits and Oscillations of stars, will carry 26 cameras to study Earth-like planets in habitable zone orbits around ...

  9. Habitability of red dwarf systems - Wikipedia

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

    For planets to retain significant amounts of water in the habitable zone of ultra-cool dwarfs, a planet must orbit very near to the star. [30] At these close orbital distances, tidal locking to the host star is likely. Tidal locking makes the planet rotate on its axis once every revolution around the star.
