    Astronomers search for stars similar to the Sun in order to understand how the Sun formed and if it is unique. So far, the stars we've found that are like the Sun have had notable differences. The closest candidate was analyzed recently and found to have a composition that strongly resembles our Sun. The research gives us ideas about the nuclear fusion processes that take place in the cores of Sun-like stars and clues about the formation of planetary systems.
