  2. 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 ...

  3. List of potentially habitable exoplanets - Wikipedia

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

    This is a list of 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 composition. [ 4 ]

  4. List of nearest exoplanets - Wikipedia

    en.wikipedia.org/wiki/List_of_nearest_exoplanets

    The first report of an exoplanet within this range was in 1998 for a planet orbiting around Gliese 876 (15.3 light-years (ly) away), and the latest as of 2024 is one around Struve 2398 A (11.5 ly). The closest exoplanets are those found orbiting the star closest to the Solar System, which is Proxima Centauri 4.25 light-years away

  5. Proxima Centauri b - Wikipedia

    en.wikipedia.org/wiki/Proxima_Centauri_b

    Proxima Centauri b is the closest exoplanet to Earth, [19] at a distance of about 4.2 ly (1.3 parsecs). [4] It orbits Proxima Centauri every 11.186 Earth days at a distance of about 0.049 AU, [1] over 20 times closer to Proxima Centauri than Earth is to the Sun. [20] As of 2021, it is unclear whether it has an eccentricity [e] [23] but Proxima Centauri b is unlikely to have any obliquity. [24]

  6. Habitable zone for complex life - Wikipedia

    en.wikipedia.org/wiki/Habitable_Zone_for_Complex...

    Planet rotation axis tilt habitable zone, or obliquity habitable zone: the region where a stable axial tilt for a planet's rotation is maintained. [41] Earth's axis is tilted 23.5°; this gives seasons, providing snow and ice that can melt to provide water run off in the summer.

  7. Habitable zone - Wikipedia

    en.wikipedia.org/wiki/Habitable_zone

    A diagram depicting the habitable zone boundaries around stars, and how the boundaries are affected by star type. [1] This plot includes Solar System planets (Venus, Earth, and Mars) as well as especially significant exoplanets such as TRAPPIST-1d, Kepler-186f, and our nearest neighbor Proxima Centauri b.

    Scientists have found a new Earth-like planet that could support alien life – just 40 light-years away.. The planet is a remarkable discovery in the search for habitable worlds: it is slightly ...

  9. List of exoplanets discovered by the Kepler space telescope

    en.wikipedia.org/wiki/List_of_exoplanets...

    The exoplanets were found using a statistical technique called "verification by multiplicity". 95% of the discovered exoplanets were smaller than Neptune and four, including Kepler-296f, were less than 2 1/2 the size of Earth and were in habitable zones where surface temperatures are suitable for liquid water.
