Sun's 8.2-billion-year-old twin found

(QHA) - About 250 light-years away in the constellation Capricornus (The Sea Goat) lies a star that looks awfully familiar, fox news reports. Known as HIP 102152, the star is a virtual twin of our sun, which in and of itself is not so unusual. But HIP 102152 is older than our 4.6-billion-year old sun -- by nearly 4 billion years, making it the oldest solar twin found to date. "It is important for us to understand our sun in the proper context of stellar astronomy and to identify which of its properties are unique and normal, to predict what its fate may someday be," astronomer TalaWanda Monroe, a postdoctoral fellow at the University of San Paulo in Brazil, wrote in an email to Discovery News.
