The Sun Case Essay
The sun is the center of solar system. All the eight planets in the solar system revolve around the sun. It is responsible for the day and the night we experience. It gives light and heat to the planets that revolve around it. Our Earth is the third closest planet to the Sun which is about 92 million miles from here to the sun (Myron, 2007). It may be far, but the Sun still provides enough light for plants to grow and enough heat for the people to be warm.
This is made possible by the Sunâ€™s very large size. The sunâ€™s diameter is about 864, 938 miles. It is 10 times bigger than Jupiter, the biggest planet in the Solar System. Compared to the Earth, the Sun is 109 times bigger than our home planet (How Big is the Sun?, 2007).
The Sun, even if it is very big, is mostly composed of gaseous elements like hydrogen and helium. It has a very hot temperature on its outer layer, and an even hotter inner layer. On the surface, it is about 5,515 degrees Celsius or 9,940 degrees Fahrenheit. Because of this very high temperature, the planets revolving around the sun receive heat and light even though they are very far apart.
Why is the sun yellowish-white in color? We see the sun as yellowish-white because of its very hot temperature. The color is also scattered when the light passes through the atmosphere. What is left of the scattered is just the yellowish-white color which we see as the color of the sun. This is why we see a different color of the sun during the afternoon, when the sun is positioned very low in the sky (Dorn, 1999).
The sun is a very magnificent body in space. It plays a very important part in our lives. We should be happy and proud that we have the Sun here in our Solar System.
