The sun is main source of energy, it is necessary for life on the Earth, without it, there is no life on the Earth. It is the main part of our solar system. With its great gravitational force, all eight plants, including Earth are orbiting the Sun. The sun is huge ball of hot, glowing gases. It is only star in our solar system. The hottest part of the sun is centre or core. 

                                           THE SUN

While billion of stars are scattered true hot the universe the one of the centre of our solar system. Plays a special role for us here on earth. I was informed about 4.5 billion years ago in the milky way galaxy. It was born when a cloud of dust and gas known as solar nebula collapsed and it's the middle of these formation matter condensed into a burning ball of gas become our sun. 

The sun's fiery nature along with great gravitational pull and an extensive magnetic field helped it to become the heart of our solar system. The sun can be divided into six layer or regions

1. The Corona

The corona is the outer atmosphere of the sun. Its often called outer part of the sun that we can see form the earth. 

2. The chromosphere 

The chromoshpere is the inner layer of the sun. Its color is red and only visible during eclipses. 

3. The photoshpere

After chromosphere, photosphere is the inner layer of the sun. It is the most hottest part of the sun, which has temperature is 10 million degrees. 

4. The connective 

In this part we found gasses such as Hydrogen and other gasses. Every second, sun releases 1 million times more energy than a Earth used in one year. 

5. Radiative zone

The heat and energy is transferred by the Radiative Zone. 

 6. The core 

The last and more hottest part is the sun is called Core, the hear and energy is produced by the core. And the core in the terms of atom count the sun is about 91% the hydrogen the sun's fuel 8.9% helium point 1% heavier elements such as carbon and nitrogen . Due to the sun's extreme temperature these element stay in a gas like phase and plasma. 

In the core temperatures reaching at least 27 million degrees Fahrenheit combined with sun powerful gravity fused together hydrogen molecules and create helium call thermonuclear fusion this release and in various amount of energy in the form of radiation electricity solar wind and as we experience on earth. 

                             All planets are orbiting the sun 

Such volatility is contained. Thanks to the sun its gravity. it's strong enough to hold the solar system intact and is primarily due to the sun's size and mass. Our sun is the largest and most massive object in the solar system. It's more than 100 Earth wide and theoretically fit all 8 planet inside nearly 600 time. 

It also contain approximately 99.8% of all the match in solar system. because of this match the sun has a great pool on the fabric space. creating a gravitational force that causes nearby planetary body to be drawn towards it. This gravitational pull allows the sun to hold together a system of eight planet, dozen of other planets, 170 moons and countless comets and asteroids. 

Without the sun's gravity these body is good drift off into deep space. Another critical property of the sun is its magnetic field which encapsulate the entire solar system. Called the heliosphere this force field protects the planets from harmful cosmic radiation. Is caused by the sun's plasma pushing electrically charged particles towards the stars poles. This process turns the sun into a giant magnet. 

Although the sun's magnetic field is invisible to the naked eye its effects are noticeable. On the surface are dark areas called sun sport, which more strong pockets of magnetism. on earth and on some of the other planet the sun's magnetic field interacts there atmosphere resulting beautiful auroras. 

Despite its size and setting the sun will not last forever in about 6.5 billion years it will run out of its hydrogen fuel expand to envelope mercury Venus and even Earth and then collapse into a small star known as White dwarf. in the meantime the sun will continue to play a critical role in the solar system that bears its name. The sun's protected magnetic field great gravitational pull and ability to create was amount of energy we will protect contain and give life to our solar system.
