Scientists Discover Our Sun’s Long-Lost Identical Twin

Most stars are born in pairs, and our star, as the Portuguese scientists found out, is no exception. Astronomers discovered a yellow dwarf HD 186302 at a distance of 184 light years from Earth, which could appear with the Sun from a single star-forming cloud 4.57 billion years ago.



The "twins" have similar size, surface temperature, spectral class and chemical composition. Astronomers will continue to research HD 186302 to learn more about the past of the Sun, as well as to find new Earth-like planets.


According to the calculations of researchers, HD 186302 was born about 4.5 billion years ago - almost simultaneously with the Sun. Scientists also noted that the similarity of HD 186302 with the Sun gives hope for the existence of earth-like planets in the vicinity of a new star.
