It might be the right distance for the so called goldylocks zone but the planet
would be sterile as it is very close to a very active Flair Star,which would make the CME's from our sun look a damp squib.
Over hype as far as I am concerned.
BTW this is the third time they have supposed to have found a planet around the Alpha Centurii system with nothing so far to show that it is real.
I really think they place to much score on the dopplar system.
