Bételgeuse (α Orionis) est une étoile variable semi-régulière de type supergéante rouge, dans la constellation d’Orion, située à une distance très difficile à établir. En 2008 un article propose la distance de 197 ± 45 pc (∼643 a.l.)[1],[a], mais elle fut définie à 427 années-lumière pendant les décennies précédentes. En 2013, le télescope spatial Herschel estime que Bételgeuse pourrait approcher la distance de 500 années-lumière[4].
