Small, Rocky Planet Discovered Circling Another Star, SpaceRef
“Researchers speaking today at the National Science Foundation announced the discovery of the smallest extrasolar planet yet found – one that resembles our own planet much more than any other yet discovered. The planet is between 6 to 9 times the mass of Earth and orbits its host star once every 1.9 days at a distance of 2 million miles.”
