Kepler-22b- A New Possible Super-Earth Discovered

Kepler-22b is a confirmed extrasolar planet found to orbit the habitable zone of a Sun-like star. Kepler-22b, a possible Super-Earth, was discovered by NASA's Kepler Space Telescope.
 
The discovery was announced December 5, 2011. The planet was originally discovered on Kepler's third day of science operations in mid-2009. The third transit was detected in late 2010. Additional confirmation data was provided by the Spitzer Space Telescope and ground-based observations. The planet's radius is roughly 2.4 times the radius of Earth; it is 600 light years away from Earth, in orbit around the G-type star Kepler-22.
