Sol is the Latin name of our Sun. At 93 million miles, it is by far, the closest star to Earth.

Alpha Centauri is the nearest neighbor of our star. It is actually a triple-star system. So there are three stars bound together by gravity. Alpha Centauri A and B are two bright, closely orbiting stars with a distant, dim companion, Proxima Centauri. The interesting thing is that this "dim companion" claims the honor of being the closest star to Earth outside of the Solar System.

As for Andromeda, it is not even a star. It is one of the most famous constellations.
