Alpha Centauri or Proximia Centauri?? Alpha is a star SYSTEM, not a star
Alpha Centauri (a&b making a binary (2) star system)
4.37 light years about 25,689,044,200,000 miles away
Alpha Proxima (known as the closest star to us)
4.22 light years about 24,807,269,200,000 miles away
I know the picture sucks, but the only one I could find with all three in the same link
