Gliese 667
Gliese 667 är ett trippelstjärnsystem i Skorpionen positionerat cirka 6.8 pc (23.6 ljusår) från Jorden. Alla tre stjärnor i systemet har en massa mindre än solen. Stjärnan Gliese 667 C, en röd dvarg och den minsta stjärnan i systemet, antas ha minst sju planeter i omloppsbana runt sig, av vilka minst tre antas kunna finna inom den cirkumstellära beboeliga zonen.[1] Gliese 667 Cc, Gliese 667 Cf, Gliese 667 Cd samt Gliese 667 Ce. En till planet finns här, Gliese 667 Cb, vilket inte är i den cirkumstellära beboeliga zonen.

This artist’s impression shows a sunset seen from the super-Earth Gliese 667 Cc. The brightest star in the sky is the red dwarf Gliese 667 C, which is part of a triple star system. The other two more distant stars, Gliese 667 A and B appear in the sky also to the right. Astronomers have estimated that there are tens of billions of such rocky worlds orbiting faint red dwarf stars in the Milky Way alone.

The 6-Earth-mass exoplanet Gliese 667Cb orbits its low-mass host star at a distance equal to only 1/20th of the Earth–Sun distance. The host star Gliese 667C is a companion to two other low-mass stars, which are seen here in the distance.
