What are the 6 regions of the sun?
How does the sun produce energy?
The sun has a temperature of about 13,600,000K, it produces energy by nuclear fusion through some steps named the proton-proton chain. The core produces 99% of the heat through fusion. In the sun, hydrogen atoms are excited by the pressure and heat, they fuse together and make an atom of helium. This process releases an enormous amount of energy.
- Corona (outer atmosphere)
- Chromosphere (lower atmosphere)
- Photosphere (visible surface)
- Convection Zone
- Radiative Zone
- Core

- 99.8% of the earth’s mass is taken up by the sun.
- The sun is a giant ball of gas, so different parts of it spin at different times.
- There is no solid surface because it is a star.
- The temperature at the core of the sun is about 27 million degrees Fahrenheit.
- The sun has no rings around it.
- The solar atmosphere is a thin layer of gasses where sunspots and solar flares are visible.
- Eight planets, at least 5 dwarf planets, tens of thousands of asteroids, and hundreds of thousands to three trillion icy bodies and comets all orbit the sun.
- At the equator, it takes the sun 25 days to spin once, but at the poles, every 36 days it rotates on its axis once.
- A star is a ball of gas.
- Stars glow because nuclear fusion is occurring in the center of the ball of gas.
- The phase in which a star has nuclear fusion in the center a star is called a Protostar.
- The phase called a Protostar can go on for Millions or billions of years.
- During nuclear fusion the hydrogen in the star is converted to helium.
- After the Protostar phase the core of helium becomes unstable.
- As it becomes more unstable the star expands and becomes cool.
- As it cools the star turns red.
