    en.wikipedia.org/wiki/List_of_most_massive_stars

    It is the most massive star that has a Bayer designation. It was only discovered to be (at least) two stars in the past few decades. Both the obscuring clouds and the great distances also make it difficult to judge whether the star is just a single supermassive object or, instead, a multiple star system. A number of the "stars" listed below may ...
