Kepler finds tenth transiting ‘Tatooine’ exoplanet

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.
