Gliese 667Cc is an Earth-like planet located in a triple-star system in the Scorpius constellation. It’s around 22.1 light-years away from Earth and appears as one star when viewed with the naked eye.
The planet revolves around the third star in the system and is 4.16 to 4.92 times the mass of Earth. Gliese 667Cc is one of the best confirmed candidates for supporting life and liquid water, although the surface would be slightly warmer than the Earth.
Gliese 667Cc’s parent star is part of a triple-star system, so the planet’s night sky would probably be a sight to behold. More information about the planet: https://goo.gl/QyKRlh
