GJ 876 b — GJ 876 System
Cataloged by the NASA Exoplanet Archive TAP service, GJ 876 b orbits host star GJ 876 every 61.12 days at a distance of 4.68 parsecs (15.26 light-years). With a planetary radius of 13.3 R⊕, equilibrium temperature of 191 K, and habitability index of 0.55, it represents a premier target for transmission spectroscopy of water vapor, carbon dioxide, and biosignature disequilibrium gases.
