Core

This is where the process of nuclear fission occurs. It encompasses 25% of the suns radius. The temperature is hotter than 15 million K.

Radiative Zone

This is the layer where energy is primarily transferred towards the exterior. The temperature ranges from 1.5 million K to 15 million K.

Convective Zone

This is the layer that is unstable to convection. energy is primarily transferred here by convection.

Photosphere

This is the deepest layer of the sun that we can observe directly. the temperature ranges from 4000 K to 6500 K.

Corona

This is the outermost layer of the sun. The temperature is 500,000 K. This can not be seen with a naked eye.
