This is a list of the most massive stars. The list is ordered by solar mass (1 solar mass = the mass of Earth's Sun).
Stellar mass is the most important attribute of a star. Combined with chemical compositions, mass determines a star’s luminosity, its physical size, and its ultimate fate. Due to their mass, most of the stars below will eventually go supernova or hypernova, and form black holes.
