Large Rocky Planet Discovered.
Astronomers have found the most Earthlike extrasolar planet discovered so far. This new planet is about 7.5 times the mass of the Earth, and has twice the radius of our own planet. It whips every two days around a nearby star called Gliese 876, which is only 15 light years away - this star also possesses two additional giant, Jupiter-class planets. This is the first time that a rocky (or terrestrial) planet has been discovered around another star.
