Two suns found in distant planetary system

South Korean researchers say they've discovered a planetary system that has two suns.

Lee Jae-woo and Kim Seung-ri of the Korea Astronomy and Space Science Institute and Kim Chun-hwui of Chungbuk National University said the planetary system, which they've named HW Vir has had the two suns since its birth, unlike other planetary systems in which a second sun was drawn by gravitational attraction, South Korea's Chosun Ilbo newspaper reported Friday.

The report, published in the Astronomical Journal, said the HW Vir planetary system lies about 59 billion light-years from Earth.
