The Sun is the star at the center of the Solar System . It is a nearly perfect sphere of hot plasma , with internal convective motion that generates a magnetic field via a dynamo process . It is by far the most important source of energy for life on Earth . Its diameter is about 1.39 million kilometers ( 864 , 000 miles ) , or 109 times that of Earth , and its mass is about 330 , 000 times that of Earth . It accounts for about 99.86 % of the total mass of the Solar System . Roughly three quarters of the Sun ' s mass consists of hydrogen ( ~ 73 % ) ; the rest is mostly helium ( ~ 25 % ) , with much smaller quantities of heavier elements , including oxygen , carbon , neon , and iron .
