Here's the breakdown:
* Our Solar System: Consists of our Sun and all the objects orbiting it, including planets, moons, asteroids, and comets.
* Alpha Centauri: Is a triple star system (three stars) located about 4.37 light-years away from our Sun. It's the closest star system to our own.
So, while Alpha Centauri is our nearest stellar neighbor, it is not part of our solar system.
