  • The sun spins in one full cycle in 25 earth days.

The Sun's Layers

  • The sun has 6 layers the core, radiative zone, connective zone, photosphere, cromosphere, and corona.
  • Core
- The core is the very centre of the sun which is 15 million degrees Celsius. The core provides all the energy for the sun.

  • Radiative Zone
- The radiative zone covers the core and transfers the energy to the connective zone.

  • Connective Zone
- The connective zone is the next layer and it covers the radiative zone. It takes 17,000 years for the energy to go all the way to the connective zone.

  • Photosphere
- The photosphere is the sun's surface. It transfers radiation which comes to theatric as sunlight.

  • Chromosphere and Corona
- Two light layers of gas on top of the earths surface. The corona extends beyond the dwarf planet pluto. The coronas features change from eclipse to eclipse.
