40 amazing, unexpected facts about the sun that you don't know (P2)

Perhaps most people only know that the Sun is the brightest and largest star in the Solar System, providing sunlight and many nutrients - essential chemicals for life on Earth. In fact, there are many things about the Sun that will make you dizzy and unimaginable when you hear it.

21. If we departed from Earth with a normal plane with a speed of 664km / h, it would take up to 20 years without stopping to reach the Sun.

22. The Sun's equatorial diameter is roughly equal to its polar pole about 10 km, meaning that the Sun is almost a perfect sphere. But now, the Sun is not the most perfect sphere in the Solar System, because the most perfect sphere is Venus.

23. Our Earth takes 24 hours to spin around its axis, and the Sun takes up to 25 days to spin around its axis. But 25 days is in the equator; at the Sun's pole, it takes 36 days to complete one round. This is why the Sun's rotation speed is inversely proportional to the latitude. When combined with the tilt of the Sun axis, the higher the latitude, the slower the rotation speed. Imagine that if you plug a pencil through the apple in one corner, it will protrude at the top and bottom of the apple. Now, if you rotate the apple, the middle part of the apple will spin faster than the corner of the apple.

The Sun is about 24 to 26 thousand light-years from the center of the galaxy.

24. The Sun is about 24 to 26 thousand light-years from the center of the galaxy and it takes up to 225 to 250 million solar years to complete one revolution.

25. Suppose the Sun revolves around the center of the Milky Way, which takes up to 225 to 250 million years with an average speed of 220 km / sec (about 136.7 miles / sec).

26. The energy in the Sun's core is produced by nuclear reactions when hydrogen particles are burned into helium particles. The Sun can then produce around 386 billion MW (megawatts).

27. In fact, helium gas is lighter than hydrogen gas so when the hydrogen particle aggregates into helium particles in the Sun core, its mass will be reduced a little.

28. During the sun's nuclear reaction, the core temperature can reach 150 million degrees Celsius.

29. The surface of the Sun has a temperature of about 5,500 degrees Celsius, although it seems much cooler here than the core.

30. Nuclear reactions in the Sun's core cause tremendous heat and cause the core to expand. Without the massive attraction inside, the Sun exploded like a bomb.

31. The Sun has a very strong magnetic field , which is why a magnetic storm phenomenon occurs. During the period of magnetic storms, it is possible to see storms from the Sun through images: they are small black nodules or "Sunspots - Sunspots " . In a magnetic storm, the magnetic lines will twist and spin like a tornado on Earth.

The Sun has a very strong magnetic field, which is why a magnetic storm phenomenon occurs.

32. The most frequent Sun's " Sunspots - Sunspot " storms have occurred over the past 11 years, meaning that the Sun has one cycle of that behavior every 11 years.

33. Sometimes the Sun creates something called the solar wind, which is charged particles like protons and electrons, which are ejected and "blown" throughout the solar system at a rate of about 450km / s.

34. These solar winds are created when electrons and protons accumulate enough electricity and momentum to escape the center of the Sun, beyond its enormous attraction.

35. The winds from the Sun can cause interference on Earth and disturb the orbit of the spacecraft.

36. In addition, the solar wind also produces a number of polar aurora phenomena, the phenomenon of comet tails and the Aurora Borealis or The Northern Lights, " Latin sunrise" " ) is also caused by these winds.

The solar wind also produces some aurora phenomena in polar regions.

37. Earth-like planets with strong magnetic fields often deflect winds from the Sun, causing them to be pushed back and unable to contact the planet's surface.

38. Throughout human history, the Sun has a great influence on ancient culture. The Sun is often referred to as the giver and many cultures of the past glorified the Sun as a god. The Egyptians worshiped the Sun God as Ra and the Sun god of the Aztecs was Tonatiuh.

39. For centuries, astrologers considered the Earth the center of the universe and the Sun always revolved around the Earth. They claim that the Moon is the closest planet to the Earth, then to Venus, Mercury or the Sun.

40. Assuming the Sun loses its illumination surface, the whole world will be in darkness. Although in fact, the Sun's surface is so bright that it will make your retina burn long, but its core is completely black.
