Alpha Centauri

1.  Overview

Alpha Centauri is generally considered a trinary system, but AC-A and AC-B are two sunlike stars orbiting each other every 80 years or so. AC-C, or Proxima Centauri is much farther away from the other two, and it is uncertain that it is actually "captured" by the gravity of the other two or it will wander off in a million years or so.

Both A and B have habitable zones which can hold a few terrestrial planets each. Their closest approach to each other doesn't really affect the weather on those planets, but observers living there would certainly notice the change in brightness for the "star".

2.  AC-A is almost a twin of Sol.
