Gliese 12 b — Gliese 12 System
Cataloged by the NASA Exoplanet Archive TAP service, Gliese 12 b orbits host star Gliese 12 every 12.76 days at a distance of 12.21 parsecs (39.82 light-years). With a planetary radius of 0.93 R⊕, equilibrium temperature of 315 K, and habitability index of 0.76, it represents a premier target for transmission spectroscopy of water vapor, carbon dioxide, and biosignature disequilibrium gases.
