A bright-red supergiant intrinsic variable star, the second brightest star in the constellationOrion; Alpha (α) Orionis. It is the tenth brightest star in the nighttime, and one of the largest stars known.
Origin
Ultimately from an alteration of the Arabic يَد الجَوْزَاء ("hand of the central one"), from يَد + جَوْزَاء.
Jawzā, ‘the central one’, initially referred to Gemini among the Arabs, but at some point they decided to refer to Orion by that name. During the Middle Ages the first character of the name, yā’ (', with two underdots), was misread as a bā’ (', with one underdot) when transliterating into Latin, and Yad al-Jauza became Bedalgeuze. This was then misinterpreted during the Renaissance as deriving from a corruption of an original Arabic form إِبْط الجَوْزَاء.
