Alpha Centauri has a planet

This article was particularly relevant to the exoplanet detection methods we have been studying. It’s nice to know that if we ever send a probe to Alpha Centauri it will have a planet to orbit. This is indeed a very well-known system, and if we ever do travel to another star this will likely be our destination. 

It was interesting when the article explained the Doppler Shift and how it was used to detect the planet. I suspected that this would be the method they used, as it seems to be quite effective. Here is a graph of Alpha Centauri’s Doppler shift itself.
