The planetary system around Gliese 667C

This diagram shows the system of planets around the star Gliese 667C. A record-breaking three planets in this system are super-Earths lying in the zone around the star where liquid water could exist, making them possible candidates for the presence of life. This is the first system found with a fully packed habitable zone.

The relative approximate sizes of the planets and the parent star are shown to scale, but not their relative separations.
