NASA has found the first planet in a binary star system, i.e., a planet with two suns like the planet Tatooine in Star Wars. For now it's named Kepler-16b. Link The two stars at the heart of the system are some 200 light years from Earth in the constellation Cygnus. The larger, yellow star is 69 percent as massive as the sun and the smaller red star is 20 percent as big. Kepler-16b orbits the system's center of mass every 225 days. "Sometimes, the red star would set first, sometimes the orange star, sometimes they'd set touching each other, sometimes set together. So you'd get this very dynamic sunset. It's never two sunsets are the same."It sounds like fun place for tourists to visit. But, as the news story points out, it's not in a habitable zone.
