If you cast your eyes toward the constellation Cygnus, you’ll be looking in the direction of the largest planet yet discovered with the widest orbit 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 NASA’s Kepler Space Telescope to identify the new planet.
Astronomers have discovered the tenth known ‘transiting circumbinary’ planet, which orbits two stars. Like the fictional planet “Tatooine” from Star Wars, this planet has two suns in its sky. Known as Kepler-453 b, the new planet is a gas-giant six times the diameter of Earth and lies in the habitable zone of its host pair of stars.
