Habitability Assessment
✓ Classified as a Temperate Habitable Zone Candidate.
With an estimated equilibrium temperature of 288 K (+15°C / +59°F) and a radius of 1.120 R⊕, Kepler-438 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.
