List of extrasolar candidates for liquid water

Possible existence of liquid water beyond Earth

Extraterrestrial liquid water in the Solar System is likely uncommon, although it has been hypothesized to exist in some of its moons, and to have formerly existed on Mars and Venus. Extrasolar liquid water has not yet been confirmed to exist. The following list contains candidates that meet the following criteria:Confirmed object of Earth mass or greater orbiting within a circumstellar habitable zone (CHZ) May not be a star Has been studied for more than a year Confirmed surface with strong evidence for it being either solid or liquid Water vapour detected in its atmosphere Gravitational, radio or differentation models predict a wet stratum
