Liquid water habitable zone of GJ 667C with the proposed seven candidates as estimated using the updated relations in Kopparapu et al. (2013). Three of the reported planets lie within the HZ. The newly reported planets f and e are the most comfortably located within it. The inner edge is set by the moist greenhouse runaway limit and the outer edge is set by the snow ball runaway limit. The empirical limits set by a recent uninhabitable Venus and an early habitable Mars are marked in brown solid lines. The presence of clouds of water (inner edge) or CO₂ (outer edge) might allow habitable conditions on planets slightly outside the nominal definition of the habitable zone (Selsis et al. 2007).
