Habitability Assessment
✓ Classified as a Temperate Habitable Zone Candidate.
With an estimated equilibrium temperature of 279 K (+6°C / +43°F) and a radius of 2.100 R⊕, Kepler-22 b falls within the conservative empirical boundary where a solid rocky surface could sustain liquid surface water under suitable atmospheric greenhouse conditions.
Discovery Facility: Kepler.
