The official name of the new planet is Kepler 16b, but astronomers are already referring to it informally as Tatooine, after the home planet of Luke and Anakin Skywalker in the George Lucas “Star Wars” movies, which also had two suns. Indeed, a representative from Mr. Lucas’s production company, Lucasfilm, expected to participate in a news conference at NASA’s Ames Research Laboratory in California, Kepler’s home office.
So, not a moon. Or a space station. I’m so relieved.
Kepler is the first NASA mission capable of finding Earth-size planets in or near the “habitable zone,” the region in a planetary system where liquid water can exist on the surface of the orbiting planet.
