Under The Light Of Three Suns

Gliese 667 is a triple-star system located about 24 light years from us. Orbiting within the habitable zone of one of them, the red dwarf Gliese 667C, is the planet Gliese 667Cc, a super-Earth with a mass 3.8 times greater than that of the Earth. It is probably a rocky planet that could also have oceans and atmosphere. In the sky its mother star shines with an intense reddish light and has a splendid apparent size of 1.25º, almost two and a half times the Sun seen from Earth. The other two stars of the system, Gliese 667A and Gliese 667B are K-type main-sequence stars and their powerful brightness are always visible.
