Off in the distance, well beyond the planet orbit, resides a second pair of stars bound to the planetary system. Released Oct. 15, 2012. Credit: Haven Giguere/Yale Amateur astronomers have helped discover an alien planet with two suns and a twinkling twist: The entire twin-sun setup, a real-life version of Tatooine from “Star Wars,” is orbited by two more stars — a solar system that is the first of its kind known.

Image released on Oct. 15, 2012. Credit: Haven Giguere/Yale The alien planet, called PH1, is a gas giant planet slightly bigger than Neptune. Its discovery in the midst of a strange, four-star planetary system is the first confirmed world discovered as part of the Yale University-led Planet Hunters project, in which armchair astronomers work with professional scientists to find evidence of new worlds in the bountiful data collected by NASA’s Kepler space telescope. “Planet Hunters is a symbiotic project, pairing the discovery power of the people with follow-up by a team of astronomers,” said Debra Fischer, a professor of astronomy at Yale and planet expert who helped launch Planet Hunters in 2010, in a statement. “This unique system might have been entirely missed if not for the sharp eyes of the public.” Since its March 2009 launch, Kepler has found evidence of more than 2,300 candidate alien worlds. Finding a strange, new world Since its initial discovery via Planet Hunters, the existence of PH1 has been confirmed by a team of professional astronomers, who will present their work today (Oct. 15) at the annual meeting of the Division for Planetary Sciences of the American Astronomical Society in Reno, Nev. With a radius about 6.2 times that of Earth’s, PH1 is a smidge bigger than Neptune. The gassy planet spends 138 days completing a single orbit around its two parent stars, which have masses about 1.5 and 0.41 times that of the sun. The stars circle each other once every 20 days. The two other stars orbiting the PH1’s twin suns are about 1,000 astronomical units (AU) from the parent stars. (One AU is about the distance between the Earth and sun, about 93 million miles or 150 million kilometers.) source
