WebApr 24, 2024 · Depending on the type, stars have lifetimes that run from hundreds of millions to tens of billions of years. Generally, the bigger a star is, the faster it uses up its supply of nuclear fuel, so the longest-lived stars are among the smallest. The stars with the longest lifetimes are red dwarfs; some may be nearly as old as the universe itself. WebO-type main-sequence stars are main-sequence stars (luminosity class V) of spectral type O.

(A traditional mnemonic for this sequence is “Oh Be A Fine Girl [or Guy], Kiss Me.”) Additional letters have been used to designate novas and less common types of stars. Numbers from 0 to 9 are used to subdivide the types, the higher numbers applying to cooler stars. kids captioning
