Space: Earth-like Planet Detected
The lightest exoplanet yet discovered — only about twice the mass of Earth — has been detected, astronomers announced today.
"With only 1.9 Earth-masses, it is the least massive exoplanet ever detected and is, very likely, a rocky planet,"said Xavier Bonfils of Grenoble Observatory in France, a member of the team that made the discovery, which was announced at the European Week of Astronomy and Space Science at the University of Hertfordshire in the United Kingdom.
The planet was found in the famous system Gliese 581 and has been dubbed "Gliese 581 e." It was detected using the low-mass-exoplanet hunter HARPS spectrograph attached to the 3.6-metre ESO telescope at La Silla, Chile.
