Gliese 667 Cf is an extrasolar planet orbiting around a star Gliese 667C which is a member of a Gliese 667 triple star system. It is slightly less massive than Gliese 667 Cc. Orbital stability analysis indicates that it cannot be more than twice of its minimum mass. It is located in the middle of habitable zone. Although Gliese 667 Cf receives less than 60% of the visible starlight compared to Earth, it receives more infrared radiation than Earth. Based on the black-body temperature calculation, the total amount of starlight absorbed is higher.
