The first list shows a few of the known stars with an estimated luminosity of 1 million L ☉ or greater, including the stars in open cluster, OB association and H II region. The majority of stars thought to be more than 1 million L ☉ are shown, but the list is incomplete. The second list gives some notable stars for the purpose of comparison.
Some of the brightest stars in the night sky, such as Rigel and Antares, are in the list. While supergiants are typically defined as stars with luminosity classes Ia, Iab or Ib, other definitions exist, such as those based on stellar evolution. [1] Therefore, stars with other luminosity classes can sometimes be considered supergiants.
