It's the brightest star in Orion, and its scientific name is Alpha Orionis. Also, diverse astronomers over the years have compiled star catalogs that use exclusive numbering methods.|Incredibly reduced mass stars, with masses underneath 0.5 M are thoroughly convective and distribute helium evenly through the entire total star whilst on the leading sequence.
