Alpha Centauri is similar to our sun except it is a double star system (Alpha and Beta), I think you a confusing it with Proxima Centauri which orbit both Alpha and Beta. Proxima is I believe closer to us than Alpha at this time.
I believe that should be "We can't directly see it, but we THINK it is there", not "KNOW it is there." Remember "Planet X" was inferred also, and where is it now?

Hey, I liked "Starship Troopers"!! But I have to agree that "B.E" will be probably fun to watch. Everybody lighten up!
