List of potentially habitable exoplanets

This is a list of confirmed 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. Earth is included for both comparison and reference, while Venus and Mars are included for reference only. Note that mass and radius values prefixed with "~" have not been measured, but are predicted from a mass–radius relationship. } || ==Current candidates==

Some habitable exoplanets detected by radial velocity were considered as stellar artifacts by some studies. These include Gliese 581 d and g, Gliese 667 Ce and f, Gliese 682 b and c, Gliese 229 Ac, HD 85512 b and Gliese 832 c. Several other planets, such as Gliese 180 b, also appear to be examples of planets once considered potentially habitable but later found to be interior to the habitable zone. but with improved models of the circumstellar habitable zone, PHL does not consider it potentially habitable. Kepler-1638b was thought to be a possibly habitable planet with a radius smaller than after the validation. However based on the later measurement of host star parallax by Gaia, the radius of the planet was revised upward to , meaning it is more likely an ice giant like Neptune with poor prospect for habitability. KOI-1686.01 was also considered a potentially habitable exoplanet after its detection in 2011, until proven a false positive by NASA in 2015. 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. TRAPPIST-1 d was considered to be potentially habitable until JWST/NIRSpec data found little evidence for an atmosphere with Earth-like surface pressure, highly likely ruling out habitability. ==See also==
