Unsure. Because of the close proximity to the binary system at Alpha Centauri it could be considered a tertiary system. Also it is a red dwarf star so isn't burning very hot and is quite small. You'd be best off looking at other yellow dwarf stars since we know with absolute certainty that can sustain life
This year is the 50 anniversary of the Drake Equation.....this is the famous back of fag packet contention, that if you take the number of stars in a galaxy, x by the number of observable galaxies....allow for a long shot number of planets, then another long shot capable of sustaining life, you've got a lot of potential aliens.
Frank Drake went on to start SETI (Search for Extra-Terrestrial Intelligence).....which is still going today in various forms.
Drake's project was to scan various sectors of the cosmos for radio waves, which might have come from intelligent life. He, or his successors have yet to find any.
Others have gone for optical route of looking for incoming lasers, or the outgoing route of sending our own messages out to alert aliens.
It is possible to get involved in the search.....could give fB something to do....
