g C: GJ 667Ca - System might also contain a gas-giant planet and an additional super-Earth with an orbital period of 75 days. However, further observations are needed to confirm them.
g C: GJ 667Cb - Planet of about six Earth-masses (0.018 Jupiter-Masses) orbits around 0.05 AUs, completing revolution in 7.2 days
g C: GJ 667Cc - with an orbital period of 28.15 days and a minimum mass of 4.5 times that of Earth. It receives 90 percent of the light that Earth receives. However, because most of its incoming light is in the infrared, a higher percentage of this incoming energy should be absorbed by the planet. When both these effects are taken into account, the planet is expected to absorb about the same amount of energy from its star that the Earth absorbs from the Sun.
g D: NA
Habitable zone
g A: To be warmed sufficiently have liquid water at the surface, an Earth-type rocky planet around Star A would have to have an orbital distance around 0.35 AU, with a year lasting less than 88 days. Star probably is not luminous enough to support an Earth-like world in an orbit similar to that of Earth around Sol.
g B: To be warmed sufficiently have liquid water at the surface, an Earth-type rocky planet around Star B would be located with 0.23 AU and a period of less than 49 days. Star probably is not luminous enough to support an Earth-like world in an orbit similar to that of Earth around Sol.
g C: Water zone would be located at around 0.02 AU with a period of only days; at such a close distance, a planet would probably be tidally locked.
g D: NA
Orbital map
g See map
g Stars A and B have an average separation of 12.6 AUs (a semi-major axis of 1.81") in a highly eccentric orbit (e= 0.58). The orbital period takes 42.15 years to complete
g Stars A and B have been separated from Star C by 56 to 213 AUs (8 to 30.5") at an orbital inclination of 139° to 215 AUs (30.8") at an inclination of 136°
