Alpha Centauri Bb was a proposed exoplanet orbiting the K-type main-sequence star Alpha Centauri B, located 4.37 light-years from Earth in the southern constellation of Centaurus. Its existence was announced in October 2012 but in October 2015, a scientific paper disproved the existence of the planet. Alpha Centauri B dominates the sky. Just above it to the right is a very bright star: Alpha Centauri A. And above that to the right is another star: our sun.
