Alpha Centauri is one of the brightest stars in the southern sky (in fact, it is a triple system). 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. The candidate was detected using the HARPS instrument on the 3.6-metre telescope at ESO's La Silla Observatory in Chile. The planet's existence was challenged by Hatzes (2013) and was shown to be likely an artifact caused by the data sampling by Rajpaul et al. (2015).
