Our sun is 4.5 million years old, and 150 million kilometers away from Earth. The sun is made up of 75% hydrogen and 25% helium. At the core of the sun, the temperature is very hot, about 15 million degrees Celsius. The chromosphere is about 8,300 degrees at the edge, the photosphere is 6,000 degrees K, and the corona is about 1 million degrees. Along with these extreme temperatures comes many benefits and downfalls that could either hurt or help us. Experts and scientist always tell us that we should avoid sunlight as much as possible. The sun can cause wrinkles, skin cancer, discolored skin, and even tumors. It is also a proven fact that people under the age of 18 that have been exposed to a large amount of sunlight are more likely to develop melanoma later in life. Even though the sun can harm our skin it can also help us with our health and bodies. One way that we benefit from the sun is that it gives us warmth. This warmth warms up our bodies which increases cell function and allows us to be more energized throughout the day. Our bodies synthesize vitamin D from the sun to maintain good calcium levels and healthy lives. Without the vitamin D from the sun we would not have the strong bones and teeth we need to live a healthy life. Many people say that the sun has no purpose, but actually it does. Without the sun there would be no life on Earth. The sun provides the energy that all matter on Earth needs to survive. The amount of energy released from the sun to the Earth can be affected by different changes on both the sun and on Earth. An increase in sunspots on the sun causes the amount of energy released from the sun to decrease. So the more sunspots there are on the sun the less energy the sun gives off. This increase in sunspots can be both a benefit and a downfall. When there are more sunspots we don’t get as much energy but it also cools the Earth down.
