8 INTRESTING FACTS ABOUT SUN THAT WE ALL MUST KNOW

1. The current age of sun is 4.6 billion years and it will exist for another 5 billion years.

2.Sun is nearly a perfect sphere. The diameter between its poles and the diameter between the two most outward and opposite points on equator have a difference of just 10 kilometers.

1. The diameter of this star is 1,392,684 kilometers while its circumference calculated at its equator is 4,370,005.6 kilometers.

2. The surface temperature of the star is 5,500 degrees Celsius while the temperature at its core can reach up to 27 million degrees on Celsius scale.

3. The sun’s total mass is 1,989,100,000,000,000,000,000 billion kilograms, which is 333,060 times the total mass of Earth.

4. Light from sun takes 8 minutes and 20 seconds to reach our planet Earth. But interestingly, the same light actually takes 10,000 to 170,000 years to travel to sun’s surface from the sun’s core!

5. Hot objects are known to expand. So, sun is continuously expanding. This expansion would have caused sun to explode like a massive nuclear bomb but its internal gravitational pull prevents it from exploding.

8.Because the sun is continuously expanding, it will eventually suck in Mercury, Venus and Earth by the time all its hydrogen is converted into helium. When all hydrogen gets converted into helium, the sun will become a red giant.
