Distance to the Sun : 149.6 million km = 1.496 × 1011 m = 8.31 light minute
Radius of the Sun : 695 990 km or 109 Earth radii Mass of the Sun : 1.989 · 1030 = 333 000 kg of mass of the Earth
The surface temperature of the Sun : 5770 to the chemical composition of the sun on the surface of 70% hydrogen (H), 28% helium (He), 2% other elements (C, N, O, ...) by weight
The temperature in the center of the Sun : 15.6 million to the chemical composition in the center of the Sun : 35% hydrogen (H), 63% helium (He), 2% other elements (C, N, O, ...) by weight. Thus a sun storm can knock off our electric grid as well as radio and mobile phone networks!
