Gliese 667 Ce is an exoplanet orbiting the star Gliese 667 C, which is a member of the Gliese 667 triple star system. It is slightly less massive than Gliese 667 Cc. It is located in the habitable zone. Its stellar flux is about a third of Earth's, but it could have liquid water on its surface if enough greenhouse gases are present.[2]
