THE SUN

The dark spots on the sun are the sunspots
The sun is not only at the center of our solar system, but it also enables us to live on earth. Because of this close relationship with the sun, the area in space near the earth is affected by any sun activity.
The sun has three different layers. The inner layer, the photosphere, is the brightest and the
coolest layer. The chromosphere is the
red colored second layer. The corona is
the outer atmosphere. The corona’s
temperature rises up to above a million degrees Kelvin. <
