BEIJING, Oct. 16 (Xinhuanet) -- A planet in solar system with four suns was discovered by the cooperation of amateur astronomers and professional scientists.
The finding was presented Monday at the annual meeting of the American Astronomical Society's Division for Planetary Sciences in Reno, Nevada.
The Neptune-sized gas giant, named PH1, was found by volunteers working with professional scientists in the Yale University-led project named Planet Hunters.
Supported by NASA, the National Science Foundation Astronomy and Astrophysics Postdoctoral Fellowship, researchers find evidence of new worlds in the bountiful data collected by NASA's Kepler space telescope.
The gas planet, 5,000 light-years away from our earth, orbits its twin parent stars, which is orbited by another pair of stars. And the planet circles them about every 138 days.
"Although PH1 is a gas giant planet, even if there is a possibility of rocky moons orbiting the body, their surfaces would be too hot for liquid water to exist," said researcher Meg Schwamb of Yale University.
