The extra-solar planet GJ667Cc (or Gliese 667Cc) has been declared the most Earth-like object known outside of our solar system. It orbits a type of star which is studied at the Institute of Theoretical Astrophysics.

Comparison of the planets that are currently the promising candidates for potentially habitable worlds.  The Earth Similarity Index (ESI) describes how similar an object is to Earth and ranges from zero (no similarity) to one (identical to Earth). The surface temperature, which is the most important factor in the ESI, depends much on the distance to the host star. The zone around a star, where the surface temperature allows for the existence of liquid water on the planetary surface, is called habitable zone.  Gliese 667Cc is located in the habitable zone of its host star and is currently the most Earth-like planet known (ESI=0.82).
