Nearest Rocky Planet Outside Our Solar System Found

Astronomers have confirmed the discovery of the nearest rocky planet outside of our solar system.
The planet orbits a star in another solar system about 21-light years away. It cannot be seen from Earth with the naked eye. The planet is bigger than Earth, but it's too close to its star to sustain life.
The newfound world doesn't have a very good name yet -- it's just called HD 219134b. The planet was first detected using the Galileo National Telescope in the Canary Islands. NASA's Spitzer Space Telescope confirmed the finding.
