The smaller the mass of the star, the longer it lives.


If the star has smaller mass than the Sun, it can fuse hydrogen into helium for atleast a trillion years. The larger a star, the shorter its life because it fuses hydrogen into helium much more quickly. A star whose mass is more than 20 Suns will run out of hydrogen in only a few hundred million years.
