Once Nicholas Copernicus said that the planets revolves around the sun. Everyone doubted his statement but later he was proven right. Sun is the dominant natural source of light and heat for our planet. Our planet has been dependent on this light and heat source for millions of years. Some civilizations even respected sun as their god. Today, MerrySpell team is there to enlighten your knowledge with some interesting facts about the Sun.
Interesting facts about the Sun:
1. Sun is orbited by 9 planets:
Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, Neptune and Pluto (dwarf planet) revolves around the sun for millions of years.
2. Classification of the Sun:
After a comprehensive research, scientists now classify Sun as a G2 dwarf. They have considered its chemical properties and massive size to give justification to this classification. In other words, Sun is a medium-sized star.
3.Age of Sun:
Based on its chemical and molecular structure scientists have finally estimated the age of Sun. It is estimated that our Sun is around 4.6 billion years old. Till now it has only completed half of its total lifespan.
4. The Sun is burning:
The heat and light we receive from the sun is the result of constant combustion of inflammable gas present in sun’s structure. Every single second the Sun burns around million tons of hydrogen to emit light and heat.
5. Size of the Sun
Presently it is estimated that our sun covers about 99.85 percent mass in our entire solar system.
6. Why it is burning:
Till now the Sun has been using Hydrogen to sustain its light and heat for the burning process. Scientists have estimated that this will burning process will continue for the next five billion years. After billion years it is predicted that the sun will start burning on helium from its core.
7. The chemical activity:
Our Sun faces major activity surges in its molecular structure in every 11 years. A massive cloud gets created in the solar system when the crust of the sun explodes.
8. The magnetic properties of the sun:
In every 11 years, the sun witnesses a complete reversal of its magnetic properties. This phenomenon makes the North Pole become the south and the South Pole north.
9. Sun is the closest star:
There are countless stars in our universe. But did you know the fact our sun is the closest star to our planet. The sun is 149.60 million kilometres away from the surface of the earth.
10. Extreme temperature of the Sun
You will be amazed to know that the core of the sun burns at around 15 million degree Celsius. This is the reason why we are able to utilize sun’s heat even after being so far from its source. Kuddos to solar energy!
11. The sun also rotates:
Just like planets from our solar system, the Sun also rotates on its axis. However, due to its huge size it takes around 25.38 Earth days to complete a single rotation on its axis.
12. Sun is super powerful:
The energy generated from the sun is intense. In fact, it is perhaps the greatest source of power to mankind. It is estimated that it would take around 100,000,000,000 tons of lethal dynamite to match the energy level produced every second by our sun.
13. Ice age might come again:
Scientists have estimated that even a minute change in sun’s activity change the course of its heat level which can further affect earth’s average temperature by 2 degree Fahrenheit.
