An intriguing suggestion from computer modelling suggests that Proxima Centauri, along with it's potentially habitable planet, may have been captured by the binary stars of Alpha Centauri at some time in the past:
Our closest star system may be home to a stolen star and planet
While certainly not proof, it's good to see the idea of wandering stars and planets being captured becoming more acceptable. In this case, suspicions are already high because the star Proxima apparently has a very different chemical signature to Alpha, suggesting that both stars did not form from the same disc of matter.
