The Sun orbits the Galactic Center at a distance of 24,000 to 28,000 light-years. From Earth, it is () or about 8 light-minutes away. Its diameter is about (), 109 times that of Earth. Its mass is about 330,000 times that of Earth, making up 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.
