5. The sun constantly generates a huge amount of energy as a result of nuclear fusion, and the temperature in the middle of this space reactor reaches fifteen million degrees Celsius. On the surface, the temperature is lower and is about 5600 degrees.
6. Light travels from the Sun to the Earth for about eight minutes. Although it takes only a few minutes for this energy to travel an average of 150 million kilometers, millions of years have passed since it was formed in the core and released from the surface of the sun.
7. Since the Earth moves around the Sun in an elliptical orbit, the distance between the Earth and the Sun varies from 147 to 152 million kilometers. This distance is called an Astronomical Unit (AU for short).
8. The age of the Sun is about 4.6 billion years and during this time it has used about half of the hydrogen, but the reserves will be enough for about another 5 billion years. Today, our star can be classified as a main sequence star or a Yellow Dwarf.
9. The Sun has a very strong magnetic field, and flares and sunspots on its surface are manifestations of magnetic storms. In sunspots, magnetic lines twist and turn, just like tornadoes on Earth.
