Sun is a crucial reason for our existence. Without the Sun there would be no existence of life on Earth as it is responsible for the process of photosynthesis and generating oxygen with the help of plants. It gives us energy directly as well as indirectly in many forms such as heat and light, solar energy, oxygen, etc.
The Sun is a powerful star. It holds a very important position in our solar system. Earth and other planets revolve around it. They revolve only because of Sun’s position and the gravitational pull of the Sun keeps all of them in their elliptical orbit.
The Sun is the nearest star to the Earth. Its light takes about 8 minutes to reach the Earth as it is 150 x 1,00,000 kilometers away from the Earth. Sunlight travels at the speed of 3,00,000 kilometers per second. The Sun and sunlight are very crucial for us as we can imagine only a cold and dark Earth without it.
This big ball of fire holds temperature which is unbearable for any life form. It has a temperature of about 6000 degrees Celsius on its surface and the temperature at its center is about 20 million degrees celsius. It is not a solid body. It consists mostly of hydrogen gas.
We should be grateful for this asset we have. It has given us so many resources to live our lives. But we cannot enjoy its benefits forever as research and findings predict that this star will die in 5 billion years and Earth will also no longer exist due to its dependence on Sun for its survival.
