Alpha Centauri A

Alpha Centauri A is a G-type main-sequence star, slightly larger and more luminous than the Sun, with a radius 1.22 times that of the Sun and 1.1 times its mass. It's part of the closest star system to Earth, about 4.37 light-years away. Despite no confirmed planets orbiting it, its proximity and similarities to the Sun make it a prime focus for astronomical research, particularly in the search for Earth-like planets and potential life. The Alpha Centauri system, including Proxima Centauri, is a target for future exploration missions like Breakthrough Starshot.
