During its activity, more than 1,000 confirmed exoplanets were discovered. Even Last July, NASA announced that Kepler had found the most Earth-like planet ever spotted – a small, rocky planet named Kepler 452b and nicknamed “Earth 2.0” – at 1,400 light years from Earth. Recovering Kepler from the emergency is the team’s No. 1 priority at NASA. Their next part of their mission had been to orient the telescope towards the center of the Milky Way. Kepler , a space observatory used by NASA to discover Earth-size planets orbiting other stars, was launched on March 7, 2009. Kepler’s sole scientific instrument is a photometer that continually monitors the brightness of over 145,000 main sequence stars in a fixed field of view.
