Planet with two Suns

Its_gora

A giant and frigid planet that enjoys double sunsets as it circles two stars has been spotted in the northern skies.
Astronomers said the planet, named Kepler-16b, marked the first unambiguous discovery of a world in orbit around two stars – an oddity made famous by the planet Tatooine in Star Wars.
The planet, which lies about 200 light years from Earth and has a similar mass to Saturn, was observed by Nasa's Kepler spacecraft as it passed in front of its twin suns, causing light from the stars to dim.
The unusual arrangement means that an observer on the planet's surface, where temperatures range from -70C to -100C, would see two small suns rise and set together, and on occasion appear as one as they passed in front of each other.
