SUN YELLOW DWARF ENCYCLOPEDIA Equatorial diameter 1.39 m km Mass 1.99×10'30 kg Gal. center distance 26 038 lY Rotation period 25 days Galactic orbit period 225 m years Surface gravity 274m/s 2 Surface temprature 6000 k [ 5505°c] The sun also referred to as " sol" , is the star at the center of the solar system. Sun's mass accounts for some 99.86℅ of the total mass of the solar system . COMPOSITION Roughly three - quarters of the sun's mass is hydrogen , with the rest mostly helium. only 1.69℅ of the sun ( which is still 5628 times the mass of the earth) is only made up of heavier elements like carbon, iron, neon and oxygen. DISTANCE The mean distance of the sun from the earth is approximately 144.6 million kilometers (1.AU) . on average , it takes light from sun about to 8 minutes and 19 seconds to reach the earth. STRUCTURE the photosphere is a thin outermost layer of the sun below photosphere the sun becomes opaque. However , the photosphere it self is only slightly less opaque then the air on earth. CONVECTIVE ZONE Thermal columns carry hot materiel to the surface of the sun . once the material cools off, it plunges back toward the hot radioactive zone. RADIOACTIVE ZONE The radioactive zone carries the intense heat of the core outward as thermal radiation, with materials rapidly cooling and the density of solar material decreasing a hundred fold from the top of the core to the top of the radioactive zone. CORE 99% of all power generated by the sun comes from within 24℅ of the sun's radius. @Quantum90_bot
