KOI-1686.01 was also considered a potentially habitable exoplanet after its detection in 2011, until proven a false positive by NASA in 2015. [ 72] Several other KOIs, like Kepler-577b and Kepler-1649b, were considered potentially habitable prior to confirmation, but with new data are no longer considered habitable.
This list of nearest terrestrial exoplanet candidates contains possible terrestrial ("rocky") exoplanets spaced at a distance of up to 50 light-years from the Solar System, ordered by increasing distance. [ 1][ 2][ 3] They may be composed primarily of silicate rocks and/or metals. Within the Solar System, the terrestrial planets are the inner ...
On February 26, 2014, NASA announced the discovery of 715 newly verified exoplanets around 305 stars by the Kepler Space Telescope. 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 ...
Kepler-452b (sometimes quoted to be an Earth 2.0 or Earth's Cousin [3] [4] based on its characteristics; also known by its Kepler Object of Interest designation KOI-7016.01) is a super-Earth exoplanet orbiting within the inner edge of the habitable zone of the sun-like star Kepler-452 and is the only planet in the system discovered by the Kepler space telescope.
List of nearest exoplanets. Fomalhaut b (Dagon), 25 light-years away, with its parent star Fomalhaut blacked out, as pictured by Hubble in 2012. [ 1] In 2020 this object was determined to be an expanding debris cloud from a collision of asteroids rather than a planet. [ 2] There are 7,026 known exoplanets, or planets outside the Solar System ...
The planet has 6.9 Earth masses and 1.8–2.4 Earth radii, and with its close orbit receives 40 percent more stellar radiation than Earth, leading to surface temperatures of about 60° C. HD 40307 g, a candidate planet tentatively discovered in November 2012, is in the circumstellar habitable zone of HD 40307.
Proxima Centauri b is the closest exoplanet to Earth, at a distance of about 4.2 ly (1.3 parsecs). It orbits Proxima Centauri every 11.186 Earth days at a distance of about 0.049 AU, over 20 times closer to Proxima Centauri than Earth is to the Sun. As of 2021, it is unclear whether it has an eccentricity but Proxima Centauri b is unlikely to have any obliquity.
Gliese 581c / ˈɡliːzə / ( Gl 581c or GJ 581c) is an exoplanet orbiting within the Gliese 581 system. It is the second planet discovered in the system and the third in order from the star. With a mass about 6.8 times that of the Earth, it is classified as a super-Earth (a category of planets with masses greater than Earth's up to ten Earth ...
