The Sun
The Sun
The sun is the largest object in the solar system. It is a middle-sized star and there are many other stars out in the universe just like it. Even though it is only a middle-sized star it is large enough to hold over 1 million Earth 's inside if it were hollow. The temperature on the sun is far too much for any living thing to bear. On the surface it is 10,000 degrees Fahrenheit and the core is a stunning 27,000,000 degrees Fahrenheit. But don 't worry we are over 90,000 million miles away, the sun could never reach us, at least not yet. The sun is a still a middle aged star and later in its life it will become a Red Giant. In this stage it will get bigger, and closer to us causing a temperature increase and most likely the end of the world as we know it, but this will not take place for quite some time. But the sun is not our enemy, if it weren 't for that big ball of burning gas there would be no life on this planet at all. We need its heat, its light, and its energy. Without these our planet would be frozen over like a big ice cube and there would be no signs or traces of life ever. In total amount the sun provides about 2 pounds of energy to us every day. Yes, that 's right only 2 pounds. The sun evaporates water from the earth 's lakes, streams, and rivers. It also heats the earth and cools the earth at the same time. Without the Earth 's atmosphere to protect us from the sun 's ultraviolet rays we would be toast. This is kind of how the greenhouse effect takes place. The greenhouse effect is when the atmosphere of the earth traps heat from the sun and lets sunlight heat plants, yet prevents much of the heat from getting out. In a similar way, the atmosphere lets sunlight through to the surface of the earth. The sunlight warms the earth, but the heat that created cannot easily pass back through the atmosphere into space. Now what is going on in the sun? When we look up we just see a bright object that makes us warm, sometimes
