NASA's Kepler mission has confirmed the first near-Earth-size planet in the “habitable zone”* around a sun-like star. This discovery marks another milestone in the journey to find another “Earth.”
Kepler-452b is 60 percent larger in diameter than Earth and is considered a super-Earth-size planet. While its mass and composition are not yet determined, previous research suggests that planets the size of Kepler-452b have a good chance of being rocky.While Kepler-452b is larger than Earth, its 385-day orbit is only 5 percent longer. The planet is 5 percent farther from its parent star Kepler-452 than Earth is from the Sun. Kepler-452 is 6 billion years old, 1.5 billion years older than our sun, has the same temperature, and is 20 percent brighter and has a diameter 10 percent larger.The Kepler-452 system is located 1,400 light-years away in the constellation Cygnus.Last the gravity of the planet is twice the earth.
Since Kepler launched in 2009, twelve planets less than twice the size of Earth have been discovered in the habitable zones of their stars.http://www.nasa.gov/sites/default/files/thumbnails/image/fig6-surfacetemperaturevsenergy.gif
habitable zone*=the temperature range between 273K-373K where the water exists so we can live
