Alpha Centauri Bb (α Cen Bb) was a proposed exoplanet orbiting the K-type main-sequence star Alpha Centauri B (Toliman), located 4.37 light-years from Earth in the southern constellation of Centaurus, but there has not been enough evidence to support the claim. The claimed discovery of the planet was announced in October 2012 by a team of European observers, and the finding received widespread media attention.
