Paglalarawan
English: This artist’s impression shows the planet orbiting the star Alpha Centauri B, a member of the triple star system that is the closest to Earth. Alpha Centauri B is the most brilliant object in the sky and the other dazzling object is Alpha Centauri A. Our own Sun is visible to the upper right. The tiny signal of the planet was found with the HARPS spectrograph on the 3.6-metre telescope at ESO’s La Silla Observatory in Chile. In October 2015, astronomers from the University of Oxford published a scientific paper disproving the existence of the planet. They observed that an identical statistical analysis of randomly-generated synthetic data gave the same results as the actual astronomical data.[8] This led Xavier Dumusque, the lead author of the original paper, to concede "We are not 100 percent sure, but probably the planet is not there."
Deutsch: Diese künstlerische Darstellung symbolisiert einen Planeten, der den Stern Alpha Centauri B umläuft (dieser ist Teil eines Dreifachsternsystems, deren Mitglieder unsere nächsten Sternnachbarn sind). Das Bild wurde 2012 von der ESO anlässlich einer Entdeckungsmeldung für einen solchen Planeten veröffentlicht, die allerdings 2015 wieder zurückgezogen würde. Das Bild ist vom wissentschaftlichen Standpunkt her fehlerhaft: das Planetenbild müsste eine Überlagerung zweier Sicheln zeigen, deren Symmetrieachsen durch die Mittelpunkte der beiden jeweils verursachenden Stern verlaufen.
