Habitability Assessment

✓ Classified as a Temperate Habitable Zone Candidate.

With an estimated equilibrium temperature of 301 K (+28°C / +82°F) and a radius of 1.110 R⊕, Ross 128 b falls within the conservative empirical boundary where a solid rocky surface could sustain liquid surface water under suitable atmospheric greenhouse conditions.

Discovery Facility: La Silla Observatory.
