An exoplanet has been discovered orbiting Alpha Centauri B, which is a member of the closest star system to Earth, just 4.3 light-years away. The planet mass is (probably) of order one-to-a-few Earth masses, so it is likely a rocky planet.

The orbital period is so short that it'll be nothing more than a scorched wasteland, however it's discovery holds out the possibility that there are other planets in the system at longer periods, possibly in the habitable zone.
