  2. Habitability of K-type main-sequence star systems - Wikipedia

    en.wikipedia.org/wiki/Habitability_of_K-type...

    K-type main-sequence stars, also known as orange dwarfs, may be candidates for supporting extraterrestrial life.These stars are known as "Goldilocks stars" as they emit enough radiation in the non-UV ray spectrum [1] to provide a temperature that allows liquid water to exist on the surface of a planet; they also remain stable in the main sequence longer than the Sun by burning their hydrogen ...

  3. Planetary habitability - Wikipedia

    en.wikipedia.org/wiki/Planetary_habitability

    The separation between stars in a binary may range from less than one astronomical unit (AU, the average Earth–Sun distance) to several hundred. In latter instances, the gravitational effects will be negligible on a planet orbiting an otherwise suitable star and habitability potential will not be disrupted unless the orbit is highly eccentric.

  4. K-type main-sequence star - Wikipedia

    en.wikipedia.org/wiki/K-type_main-sequence_star

    K-type main-sequence stars are about three to four times as abundant as G-type main-sequence stars, making planet searches easier. [17] K-type stars emit less total ultraviolet and other ionizing radiation than G-type stars like the Sun (which can damage DNA and thus hamper the emergence of nucleic acid based life). In fact, many peak in the red.

  5. Superhabitable world - Wikipedia

    en.wikipedia.org/wiki/Superhabitable_world

    A superhabitable world is a hypothetical type of planet or moon that is better suited than Earth for the emergence and evolution of life. The concept was introduced in a 2014 paper by René Heller and John Armstrong, in which they criticized the language used in the search for habitable exoplanets and proposed clarifications. [2]
