Earth-Mass Planet Found Orbiting Alpha Centauri B


SPACEREFEuropean astronomers have discovered a planet with about the mass of the Earth orbiting a star in the Alpha Centauri system -- the nearest to Earth. It is also the lightest exoplanet ever discovered around a star like the Sun. The planet was detected using the HARPS instrument on the 3.6-meter telescope at ESO's La Silla Observatory in Chile. The results will appear online in the journal Nature on 17 October 2012.
