Planet Orbiting Two Suns

This artist's concept illustrates Kepler-16b, the first planet known to definitively orbit two stars -- a real-life Tatooine, from 'Star Wars.' The planet, which can be seen in the foreground, was discovered by NASA's Kepler mission.

Real-Life Tatooine Planet

NASA/JPL-Caltech

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 not thought to be habitable. It is a cold world, with a gaseous surface, and it circles two stars, just like "Star Wars" Tatooine.

This artist's concept illustrates the Kepler-16 system (white) from an overhead view, showing its planet Kepler-16b and the eccentric orbits of the two stars it circles (labeled A and B). For reference, the orbits of our own solar system's planets Mercury and Earth are shown in blue.

This star chart illustrates the large patch of sky that NASA's Kepler mission will stare at for the duration of its three-and-a-half-year lifetime. The planet hunter's full field of view occupies 100 square degrees of our Milky Way galaxy, in the constellations Cygnus and Lyra.
