Kepler-1647b: New planet is largest discovered that orbits two suns

If you cast your eyes toward the constellation Cygnus, you'll be looking in the direction of the largest planet yet discovered around a double-star system. It's too faint to see with the naked eye, but a team led by astronomers from NASA's Goddard Space Flight Center and San Diego State University used the Kepler Space Telescope to identify the new planet, Kepler-1647b. The discovery was announced today in San Diego, at a meeting of the American Astronomical Society.
