*The confirmation of the nature of CoRoT-7b as the first rocky planet outside our Solar System marks a significant step forward in the search for Earth-like exoplanets. The detection by CoRoT and follow-up radial velocity measurements with HARPS suggest that this exoplanet, CoRoT-7b, has a density similar to that of Mercury, Venus, Mars and Earth making it only the fifth known terrestrial planet in the Universe.
