In a new study, astronomers from the Institute of Astrophysics and Space Sciences in Portugal, using the latest methods and the latest data from the Gaia space telescope, found the “twin” of the Sun. Scientists discovered an almost identical twin to our sun 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. Stars form in giant clouds of dust and gas, the mass of which is hundreds of thousands of times greater than the sun. At the same time, most of the luminaries are born in pairs - at a distance of 500 astronomical units (about 75 billion km) from each other. According to expert estimates, up to 85% of all stars are in binary, and perhaps even in triple or quadruple systems. Given this, scientists have always thought it strange that the sun does not have a pair. Read more at: https://phys.org/news/2018-11-solar-s... https://www.rt.com/news/444436-suns-l...
