Not just science fiction: Planet orbits 2 suns

This image provided by NASA shows an artist's depiction showing a discovery by NASA's Kepler mission of 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 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 it not thought to be habitable. It is a cold world, with a gaseous surface, but like Tatooine, it circles two stars. The largest of the two stars, a K dwarf, is about 69 percent the mass of our sun, and the smallest, a red dwarf, is about 20 percent the sun's mass. (AP photo/NASA)

MOUNTAIN VIEW, California (AP) ? Astronomers say a bit of science fiction is now reality. They've spotted a planet orbiting two suns.

The discovery was made by NASA's planet-hunting telescope Kepler. Scientists describe the find in Friday's issue of the journal Science.

They are calling the new planet Tatooine after the fictional body in the "Star Wars" films that boasts a double sunset.

The alien world, about the size of Saturn, is frigid and inhospitable. It orbits two stars 200 light-years from Earth.

Though there have been past hints of the existence of other planets that circled double stars, scientists said this is the first confirmation.

Kepler was launched in 2009 to find out how common other planets ? especially Earth-like planets ? are in the universe.
