Sun

Sun (also called Ravi) is the name of the star very close to the center of the solar system. In almost ideal sphere shaped shapes, they are mainly made up of plasma and ionic materials, which are involved in magnetic fields. Its diameter is approximately 13,72,000 kilometers, which is 109 times the diameter of the Earth, mass about 2 × 1030 kilograms, 3,30,000 times the mass of the Earth. This mass is 99.86 percent of the total mass of the solar system. Hydrogen, the main structural material in the sun, is actually about three quarters of the total hydrogen. The most abundant element after hydrogen is helium. The heavier elements than helium are responsible for just 1.69% of the Sun, yet their combined mass is 5,628 times in mass. These heavy metals include oxygen, carbon, neon, iron etc.The average distance of the sun from Earth is approximately 14.96 billion kilometers which is considered as 1 November. However, since the orbit of the Earth changes its distance from the sun, it changes its distance from the sun in January, and moves away in July. However, the distance from the Sun takes 8 minutes to 19 seconds to reach the world. The energy of this sunlight keeps the life of almost all creatures alive. The plant produces food from this light in the photosynthesis process and the animals rely on these plants or other animals for food. In addition, sunlight plays a major role in climate and weather. The great impact of the sun on the earth is that people have been aware of that prehistoric period. In many cultures, the sun was considered to be a god. However, the scientific idea about the actual structure of the sun took a long time. Eminent scientists of the nineteenth century did not even know the exact information about the sun's structural elements and energy sources.
