About 90 percent of the stars in the universe, including the sun, are main sequence stars. These stars can range from about a tenth of the mass of the sun to up to 200 times as massive. <span> But if the body has sufficient mass, the collapsing gas and dust burns hotter, eventually reaching temperatures sufficient to fuse hydrogen into helium. </span><span>All main sequence stars (including the Sun) are powered by the fusion of hydrogen (H) into helium (He). Fusion of hydrogen requires temperatures of more than </span>10 million Kelvin<span>.</span>
