Real Life Tatooine

Kepler-16b might as well be called Tatooine, since it shares an unusual feature with Luke Skywalker’s home: Each planet orbits two suns. Although Kepler-16b does have two suns just like Luke’s home, the real-life planet is extremely cold. The stars are smaller than our sun, so a warm day on Kepler-16b would be minus 100 degrees Fahrenheit. I suppose the good news is that it means no pesky sand people.
