Planet around binary star Kepler-453 插畫檔

Kepler 453-b is the tenth transiting, so-called Tatooine exoplanet found by the Kepler spacecraft. It is a circumbinary planet, meaning that it orbits the two central stars as if they were one. From the planet, or from a satellite around the planet, it would be possible to witness double sunsets (or sunrises) as in the movie Star Wars, when Luke Skywalker gazes at the setting suns on his home planet of Tatooine. The planet is a gas giant within the systems habitable zone, taking 240 days to complete an orbit. The two stars, meanwhile, orbit each other in only 27 days.
