Habitability Assessment
✓ Classified as a Temperate Habitable Zone Candidate.
With an estimated equilibrium temperature of 321 K (+48°C / +118°F) and a radius of 2.180 R⊕, K2-125 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.
