blue supergiant greater than 1000 Kelvin supergiant A supergiant star with spectral type O or B. All blue supergiants are hot and young. Rigel, in the constellation Orion, is the best example. I

naked eye star Milky Way greater than 1000 Kelvin for many centuries asterism naked eye object brighter than 5 A star visible without visual aids

O star O, B, A, and early F 35000 K very high blue-white He II rare 3 to 6 million years early star Very hot blue star, whose spectra is dominated by the lines of singly ionized helium (see Pickering series). (Most other lines are from at least doubly ionized elements, though H and He I lines are also present.) O stars are useful because they are found in dust clouds and virtually define the spiral arms.
