Do you think you know everything you need to know about the Sun? Think again. Here are 10 facts about the Sun, grouped in a certain order. Some you may already know, while others will be completely new to you.
1. The Sun is the Solar System
We live in the world, so we think we are an equal member of the Solar System. But that would not continue from the truth. The fact that the Sun weight makes up 99.8% of the weight of the Solar System. And much of this last 0.2% comes from Jupiter. So the mass of the Earth is a small amount of the mass of the Solar System. Truly, we scarcely exist.
2. The Sun is mostly hydrogen and helium.
If you were to divide the Sun and accumulate its various elements, you would find that 74% of its weight comes from hydrogen. with 24% helium. The excess 2% incorporates the measures of iron, nickel, oxygen, and the wide range of various things we have in the Solar System. All in all, the Solar System is made generally of hydrogen.
3. The Sun is very bright.
We know some amazingly bright and large stars, such as Eta Carina and Betelgeuse. But they are far from ideal. Our Sun is a bright star. If you could take the nearest 50 stars within 17 years of the Earth's light, the Sun would be the fourth brightest star in the universe. Not bad at all.
4. The Sun is big but small
With an aggregate of multiple times the size of the earth, the Sun makes up a tremendous span of room. You could spread 11,990 planets to cover the face of the Sun. That's great, but there are very big stars out there. For example, the largest star we know of would have nearly reached Saturn if it had been placed inside the Solar System.
5. The Sun is middle-aged
Astronomers estimate that the Sun (and the planets) were formed from a solar nebula about 4.59 billion years ago. At some point, about five billion years from now, the Sun will enter a large red phase, where it swells to use the inner planets - including the Earth (probably). It will cut off its outer layers, then return to the small white spot.
6. The Sun has layers
The Sun resembles a searing ball, however it really has an inward edge. The visible surface we can see is called the photosphere, and it heats up to a temperature of about 6,000 degrees Kelvin. Below that is the transmission area, where the heat slowly moves from the inner Sun to the top, and the living coolant returns to the bottom of the pillars. This region starts at 70% in the Sun range. Below the convection area, there is a lighted area. In this area, heat can only travel through radiation. The Sun's core extends from the center of the Sun to a range of 0.2 solar radiation. That’s when temperatures reach 13.6 million degrees Kelvin, and hydrogen molecules are mixed with helium.
7. The sun is heating up, and it will kill all life on Earth
Sounds like the Sun has always been there, never changed, but that's not true. The Sun is really heating up a little. It depends on 10% more light every billion years. In fact, within a billion years, the heat from the Sun will be so high that liquid water will not be available on the earth's surface. Life on Earth as we probably are aware it will be gone for eternity. Bacteria may live underground, but the surface of the planet will be burned to the ground. It will take another 7 billion years for the Sun to reach its ultimate red phase before it expands to the point where it covers the Earth and destroys the entire planet.
8. Various pieces of the Sun pivot at various paces
Unlike the planets, the Sun is a major source of hydrogen gas. Subsequently, various pieces of the Sun turn at various speeds. You can see how fast the place rotates by following the movement of the sun's rays on the surface. The hemisphere circles take 25 days to complete a single cycle, while the features on the poles can take up to 36 days. And the inside of the Sun seems to last for about 27 days.
9. The external atmosphere is more sweltering than the surface
The Sun's surface reaches temperatures of 6,000 Kelvin. But this is actually much less than the spirit of the Sun. Above the surface of the Sun, there is a wind region called the chromosphere, where temperatures can reach 100,000 K. But that is nothing. There is a very distant region called the corona, which reaches a much larger mass than the Sun itself. Corona temperatures can reach up to 1 million K.
10. There are spacecraft looking at the Sun right now.
The most famous spacecraft sent to observe the Sun by the Solar and Heliospheric Observatory, built by NASA and ESA and launched in December 1995. SOHO has been noticing the Sun ceaselessly from that point onward and sent innumerable pictures. The latest mission is NASA's STEREO space. This was actually a dual spacecraft, launched in October 2006. The twin spacecraft are designed to view the same activity in Sun from two different locations, to give a 3-D view of the Sun's work, and to allow astronomers to better predict the weather.
