Is there life on Gliese 667Cc?
Is there life on Gliese 667Cc?
Gliese 667Cc is located in the habitable zone of its host star and is currently the most Earth-like planet known (ESI=0.82). The planet GJ667Cc is even more similar to our Earth than Kepler-22b, which was confirmed as a potentially habitable planet just a few weeks ago.

How big is Gliese 667Cc compared to the Earth?
Gliese 667Cc is an extrasolar planet that’s located in the constellation Scorpius. With approximately 4.5 times the mass of the Earth, the planet is considered a “super-Earth.” By definition, a super-Earth is an extrasolar planet with a mass higher than Earth’s, but substantially below the mass…
How big is Gliese 667 compared to Uranus and Neptune?
Gliese 667 Cc is a super-Earth, an exoplanet with a mass and radius greater than that of Earth, but smaller than that of the giant planets Uranus and Neptune. It is heavier than Earth with a minimum mass of about 3.7 Earth masses. [2]
Where was the red dwarf Gliese 667Cc found?
Gliese 667Cc Gliese 667Cc (ESI=0.85) was discovered in 2011 orbiting a red dwarf in the Gliese 667 triple star system, just 24 light years away. It was found by the radial velocity method, which is a measure of the small movement a star makes as it responds to the gravitational tug of the planet.
How long do stars like Gliese 667 C live?
As a result, stars like Gliese 667 C have the ability to live up to 100–150 billion years, 10–15 times longer than the Sun will live. The planet is likely tidally locked, with one side of its hemisphere permanently facing towards the star, while the opposite side is shrouded in eternal darkness.
