The Sun
What is the Sun?
The sun is the energy source of our planet. Our sun is about 1.4 million kilometer wide. We can fit over 1 million Earth size inside it. The sun is filled with scorching hot gasses. It's temperature is is 5 500 ˚C on the surface however it's core reaches up to 4 billion ˚C.
The sun's layers order:
*Core
*Radiation Layer
*Convection Layer
*Photosphere
*Chromosphere
*Corona Layer

Core
The core is the sun's energy source. It keeps the output of the energy constant.
The core is filled with highly compact hydrogen atoms.
The core can reach up to 4 billion ˚C.
With the enormous amounts of heat it is producing it creates plasma and nuclear reaction.

Radiation Layer
The radiation layer can reach up to 14 million ˚C.
When the core releases energy by atoms, it takes 170 000 years to reach the Radiation Zone.
The radiation layer is cooler than the core.

The radiation layer is cooler than the core.
Convection Layer
The Convection Layer is known as the convection zone.
The Temperature of the Convection Layer is 2 million ˚C.
When the hot bubble gas rises up to the surface, it causes the rising and the falling of the granules.
A granule is a convective cell that is hotter than it's surroundings and can last for a few minutes.

Photosphere
The Photosphere is the coolest part of the sun, it's temperature can only go up to 6000 ˚C.
Photosphere has sunspots; sunspots are dark cooler parts of the surface.
Sunspots can last for an hour or a month.
The photosphere is an apparent surface of the sun made out gas.

Chromosphere
The Chromosphere has a red appearance and its about 2000km think. It's temperature is between 6000˚C - 50 000˚C.
It is a hydrogen layer and has jagged edges that looks like flames.
The energy it receives from the core is transported by radiation.
It shoots flames that can reach 400 000km and can last for a few days or a few weeks.

Corona Layer
The corona layer is the outer layer of the sun.
The corona can only be seen if the sun is blocked, e.g. solar eclipse, lunar eclipse.
The corona is just a thin layer that stretches out to space.
