Gliese 667 Cb is an exoplanet orbiting the star Gliese 667 C, a member of the Gliese 667 triple-star system. It is the most massive planet discovered in the system and is likely a super-Earth or a mini-Neptune. Orbital-stability analysis indicates that it cannot be more than twice its minimum mass. It orbits too close to the star to be in the habitable zone.[1] Eccentricity analysis indicates that Gliese 667 Cb is not a rocky planet.[2]
