Worlds without end: Astronomers have found a solar system with six exoplanets, three in the habitable zone.
These planets orbit the third fainter star of a triple star system. Viewed from one of these newly found planets the two other suns would look like a pair of very bright stars visible in the daytime and at night they would provide as much illumination as the full Moon. The new planets completely fill up the habitable zone of Gliese 667C, as there are no more stable orbits in which a planet could exist at the right distance to it.
The planets in the habitable zone are all super-Earths.
