How big can a star get?
But Figer found no stars larger than about 130 solar masses. Mindful of limits to the accuracy of his observations, Figer says that a reasonable upper limit to a star’s mass is about 150 solar masses. He adds that his results indicate there is only a 1 in 100 million chance that stars have no upper limit to their mass.
