Where the Sun Sets Twice. NASA’s Kepler mission has discovered a world where two suns set over the horizon instead of just one. The planet, called Kepler-16b, is the most “Tatooine-like” planet yet found in our galaxy and is depicted here in this artist’s concept with its two stars. Tatooine is the name of Luke Skywalker’s home world in the science fiction movie Star Wars. In this case, the planet is not thought to be habitable. It is a cold world, with a gaseous surface, but like Tatooine, it circles two stars.
