47 UMa b — 47 UMa System
Cataloged by the NASA Exoplanet Archive TAP service, 47 UMa b orbits host star 47 UMa every 1078 days at a distance of 13.8 parsecs (45.01 light-years). With a planetary radius of 13.2 R⊕, equilibrium temperature of 215 K, and habitability index of 0.55, it represents a premier target for transmission spectroscopy of water vapor, carbon dioxide, and biosignature disequilibrium gases.
