October 16, 2012
University of Oxford said in a statement on Monday that its astronomers joined the team to identify the planet, which is called PH1 and located 5,000 light-years away in the constellation of Cygnus.
It orbits one pair of stars, and in turn has a second pair of stars revolving around it, which is like four suns illuminating its skies. Quite how such a four star system remains stable enough not to tear it apart is a mystery.
