The beautiful and famous (at least very popular) image in the article of Alpha Centauri and Beta Centauri is very confusing. It's an image of two separate star systems, with Proxima Centauri circled in red. It is easy to make the mistake (esp. if in passing) to think that this is an image of just the Alpha Centauri system, even with the caption explanation. What looks like a star on the left is Alpha Centauri, a binary system which Proxima Centauri orbits (thus a triple star system) all about 4.3-ish lightyears away. The apparent star on the right is the similarly constructed (binary with another orbiting star) Beta Centauri triple system and is about 400 lightyears away.
