Our Sun is just one out of over 200 billion stars in our galaxy, the Milky Way. The Sun is located in the Orion arm of our galaxy about 25,000 light years from the center of the Galaxy. Kepler will be examining over 100,000 stars in our neighborhood of our galaxy in the Cygnus and Lyra constellations. Most of these stars will be somewhere between 500 and 3,000 light years from our solar system.
