Sun

Sun is a star in the center of the solar system. It kilometers 1392000 approximately miles (865 000), times about 109 of the Earth, its mass (about 2 × kg 1030, that of the earth, once 330 000) about the total mass of the Solar System 99.86 with a diameter that per cent . The rest is mostly helium, Sun about four thirds of the mass of , is composed of hydrogen. Less than 2 percent oxygen, carbon, neon, iron, is composed of heavy elements, including other This is from the earth's surface may appear yellow due to atmospheric scattering of blue light color of the Sun is white. Based on the spectral class, the classification of stars, and, G2V have been given a yellow star is the unofficial, the visible light, intense yellow-green part of the spectrum most , in this Supekutorukurasuraberu, G2 is approximately 5778 K (℃ 5505, 9941 ° F) shows the surface temperature of the order, and V (Rome) 5, Sun is, like most stars to indicate that the main sequence stars generate energy by nuclear fusion of hydrogen nuclei into helium. In its core, Sun is the fusion of hydrogen 600000000 to 430 tons per second. Once been considered a relatively insignificant little star by astronomers, Sun is currently about 85 red stars in the Milky Way percent and most of them believed to be brighter than the dwarf. The Sun has an absolute magnitude is 4.83, so the closest stars to Earth, Sun is -26.74 to create a hot day is the brightest object in the solar wind and the sky's apparent magnitude continuously expand the space corona. The flow of charged particles from the heliopause at about 100 astronomical units. Solar wind and interstellar bubbles formed in the heliosphere is the largest continuous structure in the solar system.
