The sun is the main source of warmth, energy, and light, the foundation of life on earth

 The sun is the most important and main star in the solar system. It is almost spherical, and the nearest star is the distance of the Earth, a medium-sized star with a diameter of one million three hundred and ninety-two thousand six hundred and four Eighty times the Earth's diameter is ten times larger, and its mass is three hundred and thirty thousand times that of Earth

 The sun is a yellow dwarf, although its color appears yellow when viewed from the surface of the earth

 but the color of white, and the temperature of the surface about five thousand seven hundred and seventy thousand Kelvin, while the temperature of the sun's cavity about 15 million degrees Celsius, and needs Sunlight reaches eight and nine seconds, and the temperature of one centimeter of the sun is about one million light

The sun is about the center of our galaxy - the Milky Way - about 25,000 light-years away, where billions of powerful and powerful interactions take place at every moment. The sun derives the tremendous energy it produces from the nuclear thermal reactions that occur at its center. Hydrogen gas turns to helium In a series of long interactions, these interactions are the cause of the sun's radiation activity. The interactions of the sun The massive nuclear reactions that occur continuously in the sun's cavity are the main source of energy produced by the sun

 Massive reactions occur, including the nuclear fusion of hydrogen nuclei to produce helium nuclei, which are enormous and very large, and pass through a long series of proton reactions, In which reactions occur in which the production of oxygen, nitrogen and carbon occurs in the center of the sun under extreme temperatures of about 14 million degrees Kelvin. In the heart of the sun, about ninety-nine percent of the sun's heat is produced, and in the outer region there are no clear nuclear reactions, and very few occurrences

The rest of the sun draws heat by transferring heat from the inside of the sun to the outside through radiation. The processes of convection. It is worth mentioning that the products of nuclear fusion remain concentrated in the heart of the sun, and do not go out 

The composition of the sun The sun is made up mainly of hydrogen gas. Hydrogen accounts for about three quarters of the mass of the sun. Seventy-three percent is hydrogen, the rest is helium, or 24 percent, as well as gases such as oxygen, carbon, neon, iron, sulfur , Silicon, magnesium, and some other elements in very few proportions
