Sun is a star in the center of our Solar system, with the mass that is 330.000 times greater than that of Earth. It is at the same time the biggest renewable source of energy in the world. This fiery ball mostly consists out of helium and hydrogen. Each second in its center 600 million tons of hydrogen in the process of fusion take transferred to helium, during of which a large amount of energy is released.
More energy is created in this way than a humanity produces in a year. Due to mentioned reactions the temperature in the inside of the Sun exceeds 15 million ͦC. Energy produced by the fusion process expands throughout the universe in the form of a sun light so that only a small part of it reaches Earth, where it turns into other forms of energy. About these and other interesting facts about the sun you will find out if you watch this attachment.
10FACT No 10
In the Sun were “turn off”, within a week the Earth would be 0F. In a year´s time it would dip to – 100F, and millions of years later it would be a stable – 400F.
09FACT No 9
The Sun is getting hotter, becoming 10% more luminous around every billion years. This could means that in a billion years there will be no liquid water on Earth.
08FACT No 8
The Sun is comprised of 72% hydrogen, 26%helium and other trace elements. This dense mass of gases makes up 99% of all the mass in our SOLAR SYSTEM.
07FACT No 7
The Sun puts out a huge amount of energy to heat the Solar System. Every second around 700 million tons of hydrogen are converted into helium ashes by the Sun’s fusion processes.
06FACT No 6
The Sun’s surface is colder than its atmosphere, at around 6.000 Kelvin. The atmosphere can reach 10.000 K and the region called the corona can be one million K.
05FACT No 5
The Sun is around 25.000 light years away from the center of the Milky Way galaxy. It takes about 240 million years to orbit once around the galactic center.
04FACT No 4
Different sections of the Sun rotate at varied speeds, as it is made of gas. The equator regions rotate around every 25 days, where the poles take about 36 days.
03FACT No 3
On some planetary bodies and moons there exists a “Peak of Eternal Light”, where the Sun never sets. This is due to the angle of the rotational axis in relation to the Sun.
02FACT No 2
The Sun is middle aged. Astronomers believe it formed around 4.59 billion years ago. In five billions years time it will enter the red giant phase of its life.
01FACT No 1
1.000.000.000.000 tons of dynamite would have to be detonated every single second to match the energy that the Sun produces.
