You walk outside during the morning or afternoon and you are greeted with bright light thanks to the sun. However, how much do you know about it? This glowing sphere of hot gas is incredibly interesting and there is so much that people can learn about it.
Does the Sun Rotate?
While at a considerably slower pace than many other solar system elements, the sun does rotate, or spin. However, it does this in a different way because unlike the planets which are solid, the sun is a giant ball of gas. When you compare the poles and the equator of the sun, you will learn that the equator area spins faster than the pole area.
At the equator, the sun rotates approximately one time every 24 days. However, near its poles, it only rotates approximately one time every 35 days. This information is something that scientists learned by examining the sun spots and making an observation concerning their motion. They also gleaned information about this by looking at other solar features and how they moved across the sun.
Why Does the Sun Rotate Differently Than Earth?
The Earth completes one rotation every 24 hours. This means that it moves faster than the sun and this is largely due to the fact that the Earth is solid. Since the sun is basically a flaming gas ball, it is more difficult to pinpoint its rotation. NASA says that this is because the sun does not have to rotate in a rigid manner like the solid moon and planets do.
Now you have more information about some of the basics concerning the sun. With this base of knowledge, it will be easier to build on it and increase how much you know about one of the most important elements in the solar system.
