The planet's true size and density remain unknown, however, which means it could still turn out to be a gas planet, hostile to life as we know it. The extra-solar planet GJ667Cc (or Gliese 667Cc) has been declared the most Earth-like object known outside of our solar system. enthält 1022 von Alexandria aus sichtbare Sterne. This is the band of congenial temperatures for planetary orbits -- not too close and not too far. The habitable zone is so densely packed that any additional planet is likely to destabilize the system. Gliese 832c ist ein Exoplanet, der den rund 16 Lichtjahre von der Sonne entfernten Roten Zwerg Gliese 832 im Sternbild Kranich umkreist. Scientists have, in fact, taken to calling this water-friendly region the "Goldilocks zone.". source : NASA GLIESE 667CC : Gliese 667cc: Gliese 667 Cc is an exoplanet orbiting within the habitable of the red dwarf star Gliese 667C, which is a member of the Gliese 667 triple star system, approximately 23.62 light-years (6.8 parsecs, or about 217,000,000,000,000 km) away in the constellation of Scorpius. Too big, too uncertain, or circling the wrong kind of star: Shuffle through the catalog of habitable zone planets, and the closest we can come to Earth -- at least so far -- appears to be the new kid on the interstellar block, Kepler-452b. With a mass 3.8 times that of Earth, Gliese-667Cc orbits its star in 28 days. Too close and the planet is fried (we're looking at you, Venus). Ball Aerospace & Technologies Corp. operates the flight system with support from the Laboratory for Atmospheric and Space Physics at the University of Colorado in Boulder. JPL is managed by The California Institute of Technology for NASA. Gliese 581g, which is located just 20 light years away, is likely two to three times as massive as Earth and revolves around its parent star every 30+ days.

Three of them, all Super-Earths, are located in the habitable zone. Gliese 667 Cc. Gliese 667C is a well-studied nearby star, one component of a triple-star system. There is a 12th magnitude star close to the other three, but it is not gravitationally bound to the system. It is about 22 light years away from earth. But several other exoplanet discoveries came nearly as close in their similarity to Earth. Gliese 581d orbits a red dwarf, the star has a mass of around one third of the sun. Before this, the planet Kepler-186f held the "most similar" distinction (they get the common moniker, "Kepler," because they were discovered with the Kepler space telescope). A Study of Gliese 667Cc acts as both an epilogue to the story of In Other Waters and a partial catalog of some of the life players will discover in their study of the planet. An exception is Gliese 667Cc which lies 22 light-years from Earth. This artist's conception shows the inner four planets of the Gliese 581 system and their host star, a red dwarf star only 20 light years away from Earth.
