Cool red starWhat is Sadalbari
Sadalbari is a cool, vast red giant burning with a ruby tone on the back of Pegasus. Its name comes from the Arabic «saʿd al-bāriʿ», «the luck of the excellent one», part of an old set of «fortune» stars that medieval astronomers grouped by symbolic affinity. At barely 106 light-years, it is among the closest red giants the unaided eye can contemplate.
