As we know, the Sun is a star, which is a huge, spinning, glowing sphere of hot gases. It is like a star which we can see in the night. It looks larger and brighter than any other star. We are close to the Sun, so it looks closer and brighter than other stars. It is the center of our solar system and contains the mass in the solar system.
All planets of solar system orbit around the Sun, If we look at the composition of the Sun, then we can see that it is composed of two gases hydrogen and helium. There are two conditions for its compositions. The Sun should have mass falling within a specific range. This range can be accepted between 1.4 x 1029 kg and 3.0 x 1032 kg. It is 75 times of mass of Jupiter. The 2nd necessary condition for the Sun is that it should have nuclear fusion. Nuclear fusion is a process where two lighter atomic nuclei can join or fuse to produce a dense atomic nucleus.
25 KEY FACTS ABOUT THE SUN:
If you are looking for some facts about the Sun, then you can see some interesting facts about the Sun from below. The size of the Sun is compared is not as large as compared with other know stars like red giants. If we compare it with a common type of stars in the universe like a red dwarf, then the Sun is quite larger and bigger. So we can say it is not the biggest type of star in the universe.

1. The mass of Sun is greater than any other body in our solar system. The mass of the Sun accounts for 99.86% of the mass in the solar system. If we make a comparison with Earth then we can see that its mass is 330,000 times of Earth.
2. The surface area of the Sun is 11,990 times than Earth.
3. The Sun continues to burn for 130 million years after it burns through all of its hydrogens.
4. The Sun is orbiting around the nine majors planets like Mercury, Venus, Earth, Mars, Saturn, Jupiter Uranus, Neptune, and Pluto.
5. Due to its size, it is classified as a G2 dwarf. It is a medium-sized star.
6. The present age of the Sun is estimated to be 4.6 billion years
7. There is a consumption of 4 million tons of hydrogen by the Sun every year.
8. There may be a huge production of energy when four hydrogen nuclei are combined with one helium nucleus.
9. If you consider the sheer size of Sun then you can see a 10 km difference in its polar and equatorial diameters.
10. The Sun is traveling at 220 km per second. The Sun can take 225-250 million years to complete one orbit of the center of the Milky Way.
11. When the Sun completes its red giant phase, then it will collapse. However, its mass will be retained. Further, its volume is similar to the Earth, and this condition will be called a white dwarf.
12. The Sun takes 8 minutes to reach its light on the Earth. There is a distance of 150 million Km between Sun and Earth. Light can travel at 300,000 km/S from Sun to Earth. However, the energy can reach Earth from Sun in millions of years.
13. The Sun has burned off around half at 4.5 billion years old. How the Sun is a yellow dwarf star.
14. The distance between the earth and Sun can be changed. It is possible as the Earth travels on the elliptical orbit path around the Sun. There is a great distance between the two ranges from 147 to 152 million km. There is a distance of one astronomical unit between them.
15. The Sun always rotates in the opposite direction to the Earth with the Sun. The Sun rotates from west to east while the Earth rotates from east to west.
16. The Sun always rotates quickly at its equator as compared to its poles. This rotation of the Sun is called differential rotation.
17. There is a great magnetic field in the Sun. When Sun released magnetic storms, then Solar flared occur. These are known as Sunspots, which are visible on the Earth. These sunspots are dark areas on the Sun’s surface, which is caused by magnetic variation. They look darker due to low temperatures than surrounding areas.
18. There may be a rise in temperature up to 15 million degrees celsius. Due to nuclear fusion, the energy is generated. This is due to the conversion of hydrogen to Helium. Further, we know that objects generally expand so Sun can explode like an enormous bomb.
19. The Sun always generates solar winds. These are ejections of plasma or hot charged particles, which can be originated in the layer of the Sun, which is called Corona. They travel through the solar system at up to 450 KM per Second.
20. There are three layers in the atmosphere of Sun-like photosphere, the chromosphere, and the corona.
21. The Sun is considered as a yellow dwarf star. It is a star with a surface temperature between 5000 to 5700 degrees Celsius.
22. The people from Egyptian, Indo-European, and Meso-American cultures worship the Sun.
23. In 1645 many astronomers detected no Sunspot activity on the Sun.
24. The Sun radiates heat and stream of charged particles known as the solar wind. It blows about 450 kilometers per second throughout the solar system
25. The Sun reverses its overall magnetic polarity approximately every 11 years. It’s north magnetic pole becomes a south pole.
The Sun is the star which is a nearly perfect sphere of hot plasma. The Sun is a star. There are many stars, but the Sun is the closest to Earth. It is the center of our solar system. It is a hot ball of glowing gases. If you are looking for some facts about the Sun, then this is the best article for you to see the interesting facts about the sun.
