• G-type main sequence star


  • The Sun is a G-type star.
  • The term yellow dwarf to qualify a G-type star is a misnomer, as G-type stars actually range in color from white, for more luminous types like the Sun, to only slightly yellow for the less luminous GV stars.[1]
  • Hydrogen-burning star[1]
  • G-type stars fuse hydrogen for approximately 10 billion years.[1]
  • Luminosity class V.[1]
  • From 0.8 to 1.2 times the mass of the Sun and surface temperatures between 5,300 and 6,000 K.[1]
  • Represent 7.6% of the stars in our galaxy.[1]
