“World of Two Suns”-Kepler-47 System So Compact Would Fit Inside Earth’s Orbit

Binary Stars


The Kepler-47 planetary system is an example of the diversity of solar systems outside our own. Despite having two “suns,” the entire system is so compact that it would fit inside the orbit of Earth. A team of astronomers from the Institute for Astronomy at the University of Hawaii at Manoa, discovered a third planet in the system approximately 3,340 light-years away in the direction of the constellation Cygnus.
