What is inside the sun?

Answer 1

Core (center)

•	What happens: This is where nuclear fusion occurs — hydrogen atoms are fused into helium, releasing a massive amount of energy.

•	Temperature: Around 15 million°C (27 million°F)

•	Density: Extremely dense, like 150 times the density of water.

•	Composition: Mostly hydrogen (about 70%) and helium (about 28%)

⸻

2. Radiative Zone

   • What happens: Energy from the core slowly moves outward by radiation (photons bouncing from atom to atom).

   • Temperature: Drops from about 7 million°C to 2 million°C.

   • Time scale: It can take thousands to millions of years for energy to pass through this zone.

⸻

3. Convective Zone

   • What happens: Energy is transported by convection — hot gases rise, cool gases sink.

   • Temperature: Around 2 million°C down to 5,500°C

   • What it looks like: Like boiling water — rising and falling blobs of plasma.

⸻

4. Photosphere (visible surface)

   • What we see: This is the layer of the Sun we can observe directly with our eyes or telescopes.

   • Temperature: About 5,500°C (9,932°F)

   • Sunspots: Cooler, darker areas caused by magnetic activity.

⸻

5. Chromosphere and Corona (outer atmosphere)

   • Chromosphere: A thin reddish layer seen during solar eclipses.

   • Corona: The outermost layer, extending millions of kilometers into space.

   • Temperature: Corona is incredibly hot — over 1 million°C, much hotter than the surface, and scientists are still studying why.

⸻

Summary of Composition:

•	Hydrogen: ~70%

•	Helium: ~28%

•	Other elements (oxygen, carbon, iron, etc.): ~2%

Answer 2

The Sun, our star, is a colossal sphere of extremely hot gas and plasma, held together by its own immense gravity.

The Sun is primarily composed of:

Approximately 73.46% hydrogen

Approximately 24.85% helium

Answer 3

The sun is composed mostly of hydrogen, some helium, and trace amounts of other elements. At the cor of the sun hydrogen is undergoing nuclear fusion and turning into helium, releasing huge amounts of energy.

Answer 4

Inside the sun there is a Core, Radiation Zone and Convective Zone. And on the surface there are Sun Spots

Answer 5

The Sun is a massive ball of hydrogen and helium undergoing nuclear fusion in its core. This process releases energy in the form of light and heat, which is what we see and feel here on Earth.
