A Non-Chronological Report About The Sun

Sun

The sun is a star at the center of our solar system. It provides us with not only just useful light and heat energy but also harmful gamma radiation.

How Big Is The Sun?

The sun is nearly a perfect sphere. Its equatorial diameter and its polar diameter differ by only 6.2 miles (10 km). The mean radius of the sun is 432,450 miles (696,000 kilometers), which makes its diameter about 864,938 miles (1.392 million km). You could line up 109 Earths across the face of the sun. The sun's circumference is about 2,713,406 miles (4,366,813 km).

How Was The Sun Formed?

Although it may look empty, space is filled with gas and dust. Waves of energy traveling through space pressed clouds of dust closer together, as gravity caused them to collapse on themselves and then start to spin. The spin caused the cloud to flatten into a disk like a pancake. In the center, the material clumped together to form a protostar that would eventually become the sun.

How Does The Sun Produce Energy?

The sun produces energy and radiation through nuclear fusion. Hydrogen cores fuse together into helium cores and producing heat, light and gamma radiation at the meantime. Since Earth not only receives the useful light and heat energy, it also receives harmful gamma radiation. Luckily, Earth has a protective ozone layer which blocks off the harmful rays. But there are some holes in the ozone layer due to chlorofluorocarbons (CFCs). Too prevent this from happening, conserve electricity as CFCs are a byproduct of using electricity.

What Are Sunspots?

Sunspots are darker, cooler areas on the surface of the sun in a region called the photosphere. The photosphere has a temperature of 5,800 degrees Kelvin. Sunspots have temperatures of about 3,800 degrees K. They look dark only in comparison with the brighter and hotter regions of the photosphere around them. They are caused by interactions with the Sun's magnetic field which are not fully understood. Sunspots occur over regions of intense magnetic activity, and when that energy is released, solar flares and big storms called coronal mass ejections erupt from sunspots.

Facts About The Sun.

1. At its center the Sun reaches temperatures of 15 million °C.
2. The Sun is all the colors mixed together this appears to be white to our eyes.
3. The Sun is mostly composed of hydrogen (70%) and Helium (28%).
4. The Sun is a main-sequence G2V star (or Yellow Dwarf).
5. The Sun is 4.6 billion years old.
6. The Sun is 109 times wider than the Earth and 330,000 times as massive.
