Habitability Assessment
✓ Classified as a Temperate Habitable Zone Candidate.
With an estimated equilibrium temperature of 226 K (-47°C / -53°F) and a radius of 1.900 R⊕, K2-288 B b falls within the conservative empirical boundary where a solid rocky surface could sustain liquid surface water under suitable atmospheric greenhouse conditions.
Discovery Facility: K2.
