The Closest Star to Earth
Alpha Centauri is the closest star to earth. It is 4.37 light years away from our planet. It is not a single star. It is a star system that has three stars, Alpha Centauri A, Alpha Centauri B and Proxima Centauri. But in our sky, it is visible as one single star. It is the third brightest star in the earth’s sky. Proxima Centauri, a red dwarf is too faint to be seen even with a small telescope. Alpha Centauri A is the brightest star of the system. It is a yellow star and 25% larger than the Sun. Alpha Centauri B is an orange star but a bit smaller than the Sun.
