35 things about the Sun


1. The sun is a medium-sized star, responsible for the climate, the evolution of life and most of the phenomena on Earth;

2. Sun is about 4.6 billion years old and is at the middle of his life;

3. The distance from Earth to the Sun is 150 million km;

4. The Sun's diameter is 1,392,684 km and the weight of 1,989 x 1030 kg; has a diameter of 109 times the Earth and is 330,000 heavier, being responsible for 99.86% of the mass of the Solar System;

5. The Sun is just one of the 100 billion stars in our galaxy;

6. The temperature of the photosphere (surface) is about 6,000 degrees Kelvin; core temperature reaches 15 million Kelvin degrees;

7. In the past, people believed that the Sun is a ball of fire set in the sky by the gods;

8. Without the Sun, life on Earth would not be possible;

9. It is about 25,000 light years from the center of our galaxy;

10. It consists of 72% hydrogen, 26% helium and 2% other elements (oxygen, carbon neon, nitrogen, magnesium, iron,
Silicone);

11. The Sun converts every second 700 million tons of hydrogen into 695 million tons of helium and 5 tons of gamma radiation;

12. After burning all its fuel, the Sun will burn helium for about 130 million years, during which it will become the red giant, swallowing the planets Mercury, Venus and Earth; in the last stage of life it will shrink, becoming a white dwarf;

13. The sun has an almost perfect spherical shape;

14. A complete rotation of the Sun around the center of the galaxy lasts 225-250 million years;

15. Sunlight travels 8 minutes and 20 seconds to reach Earth;

16. According to the star classification system, the Sun is a yellow dwarf;

17. Sun-released energy is produced by nuclear fusion, using hydrogen as fuel;

18. In addition to heat and light, the Sun also emits a series of particles that make up the so-called solar wind that travels through the solar system at speeds of over 450 km / s; it sometimes causes interference with the Earth's electronics and is responsible for the bourgeois aurora phenomenon;

19. Though it seems to be in place, the Sun, like any heavenly body, is turning; it performs a complete rotation around its own axis in 26 days;

20. Because it is made up of gas, different parts of the Sun are spinning at different speeds; the fastest rate of rotation takes place in Ecuador, while the rotation is slower;

21. The sun loses 5 tons every second;

22. The pressure in the Sun's core is 340 billion times the pressure on Earth;

23. Solar eruptions are violent explosions taking place in the solar atmosphere; they can reach more than 160,000 km away from the Sun;

24. Density of matter in the Sun's core is 150 times greater than water;

25. If the Sun would have a diameter of a few centuries, the nearest star would be 700 kilometers;

26. A man weighing 60 kg would weigh 1680 kg on the Sun;

27. The closest star of the Sun is Proxima Centaruri; it is 4.3 light years away;

28. The energy produced in the Sun's core needs 50 million years to reach the surface;

29. Sunspots appear as shadows on the solar surface; these are regions with a very strong magnetic field, thousands of times more powerful than Earth's;

30. The brightness of the Sun is equal to the brightness of 4 trillion trillions of 100-watt light bulbs;

31. The total amount of fossil fuels used by humans throughout history is equivalent to the energy produced by the Sun in less than 30 days;

32. If the Sun would not emit the heat, all the bodies on Earth would die frozen and the oceans would freeze;

33. On the island of Spitsbergen, Norway, during a certain period of the year the Sun shines continuously for three and a half months;

34. Over a billion years the sun will be 10% brighter than it is today;

35. The sun is a fairly bright star; if we were to take the closest 50 stars, the sun would be fourth in terms of luminosity;
