Editing Supergiant (section)

==Well-known examples==
Supergiants are rare and short-lived stars, but their high luminosity means that there are many naked-eye examples, including some of the brightest stars in the sky. [[Rigel]], the brightest star in the [[constellation]] [[Orion (constellation)|Orion]], is a typical blue-white supergiant; the three stars of [[Orion's Belt]] are all blue supergiants; [[Deneb]], another blue supergiant, is the brightest star in [[Cygnus (constellation)|Cygnus]]; and [[Delta Cephei]] (itself the prototype) and [[Polaris]] are Cepheid variables and yellow supergiants. [[Antares]] and [[VV Cephei A]] are [[red supergiant]]s. [[Mu Cephei|μ Cephei]] is considered a red hypergiant due to its large luminosity; it is one of the reddest stars visible to the naked eye and one of the largest in the galaxy. [[Rho Cassiopeiae]], a variable yellow hypergiant, is one of the most luminous naked-eye stars. [[Betelgeuse]] is a red supergiant that may have been a yellow supergiant in antiquity,<ref>{{cite journal |bibcode=2022MNRAS.516..693N |title=Colour evolution of Betelgeuse and Antares over two millennia, derived from historical records, as a new constraint on mass and age |last1=Neuhäuser |first1=R. |last2=Torres |first2=G. |last3=Mugrauer |first3=M. |last4=Neuhäuser |first4=D.
