In 2016, scientists discovered a potentially habitable planet orbiting the third star in the Alpha Centauri system, Proxima 2020-06-10 · And that’s the strategy astronomers used in looking for neighboring planets. They started by looking around neighboring stars that were close by. In fact, they’ve been looking at the closest star system, Alpha Centauri, for decades. Alpha Centauri is a bit more than four light-years away. The system is only 4.37 light-years from Earth, and this marks the first time the habitable zones of Alpha Centauri A and Alpha Centauri B have been directly imaged. Until now, habitable zone planets had not been found around either of those stars, but another star in the system, Proxima Centauri — a red dwarf star smaller than the Sun — appears to host to a possible planet in its Alpha Centauri is a three-star system (Alpha Centauri A, Alpha Centauri B, and Proxima Centauri) that is located a little over 4 light-years away from Earth. And the system may hold not one but two possibly habitable planets.

We are presently unaware of any other planets orbiting either Alpha Centauri A, Alpha Centauri B, Proxima Centauri, or the entire Alpha Centauri system as a whole. The planet candidate Alpha Centauri Bb was announced as the nearest exoplanet to Earth and also the lightest exoplanet ever discovered around a Sun- like star. Proxima Centauri b is a super Earth exoplanet that orbits an M-type star.

Call me "cautiously interested." But if it is a planet, that would be very cool indeed. Alpha Centauri is the closest star system to ours. It consists of three stars, a binary star consisting of Alpha Centauri A and B, both orbited by Proxima Centauri, a dim red dwarf. Proxima is likely to have at least two planets, and there's evidence for a
