It is almost perfectly spherical and consists of hot plasma interwoven with magnetic fields.^[12]^[13] It has a diameter of about 1,392,684 km,^[ 5] about 109 times that of Earth, and its mass (about 2x10^ 30 kilograms, 330,000 times that of Earth) accounts for about 99.86% of the total mass of the Solar System.^[14] Chemically, about three quarters of the Sun's mass consists of hydrogen, while the rest is mostly helium. The remainder (1.69%, which nonetheless equals 5,628 times the mass of Earth) consists of heavier elements, including oxygen, carbon, neon and iron, among others.^[15] Excerpt from Wikipedia. Sun ?
