Alpha Centauri is a triple star system located approximately 4.37 light-years from Earth, with its smallest member, Proxima Centauri, being the closest individual star at 4.24 light-years. The system is only visible from the Southern Hemisphere and is a favorite telescope target for observers in Australia and South America. The discovery of an exoplanet orbiting Proxima Centauri in 2016 made this system one of the most exciting subjects in modern astronomy (Deals).
