About Sadalbari
Sadalbari is an orange star of class K that has swollen well beyond the Sun’s size, its outer layers cooled to an orange glow. It is Mu Pegasi, an ageing star of a very common kind.
Its name comes from the Arabic saʿd al-bāriʿ, “luck of the excellent one”. It lies near Scheat and Matar on the horse’s foreleg, among the family of saʿd names that runs through Pegasus, Aquarius and Capricornus.
