Alpha Centauri is a binary star system located just over four light-years away from Earth, making it the closest known star system to our Solar System. It consists of two main stars, Alpha Centauri A and Alpha Centauri B, as well as a third companion star called Proxima Centauri. Research on the Alpha Centauri system primarily focuses on studying the properties of these stars, their potential exoplanets, and the possibility of habitable worlds within the system. Astronomers have discovered exoplanets orbiting both Alpha Centauri A and Alpha Centauri B, and there is ongoing research to further characterize these planets and determine if any of them could potentially host life. Overall, research on Alpha Centauri is important for understanding the diversity of star systems in our galaxy and expanding our knowledge of potential habitable worlds beyond our own Solar System.
