List of potentially habitable exoplanets
The following list includes potentially habitable exoplanets. It is mostly based on estimates of habitability by the Habitable Worlds Catalog, and data from the NASA Exoplanet Archive. The HWC is maintained by the Planetary Habitability Laboratory at the University of Puerto Rico at Arecibo.
Surface planetary habitability is thought to require an orbit at the right distance from the host star for liquid surface water to be present, in addition to various geophysical and geodynamical aspects, atmospheric density, radiation type and intensity, and the host star's plasma environment.
Main list
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. Note that inclusion on this list does not guarantee habitability, and in particular the larger planets are less likely to have a rocky composition and more likely to be mini-Neptunes. 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.
