[Artist Concept] Vulcan may not be real, but Spock's home system is. It takes a little imagination to wish some favorite fictional universes into existence. But, for legions of "Star Trek" fans, they don't have to wish: one star system really exists in our Milky Way galaxy. In Star Trek lore, Vulcan is the home of logic, learning and the deeply beloved first officer Mr. Spock. While Vulcan is fictional, the star system it belongs to-40 Eridani-is very real. It's located only 16.5 light-years away from Earth and its primary star can be spotted with the naked eye. So how much is science fiction and how much is science fact? "Could there be an Earth-like planet in this system? We have no way of knowing that now," said Karl Stapelfeldt, chief scientist of NASA's Exoplanet Exploration Program. So while Vulcan (as far as we know) doesn't exist, a fascinating triple sunset would occur on any rocky planet in the system, because 40 Eridani has three stars that circle each other.
