Habitability Assessment

✓ Classified as a Temperate Habitable Zone Candidate.

With an estimated equilibrium temperature of 305 K (+32°C / +90°F) and a radius of 1.458 R⊕, K2-3 d falls within the conservative empirical boundary where a solid rocky surface could sustain liquid surface water under suitable atmospheric greenhouse conditions.

Discovery Facility: K2.
