PARTS OF THE SUN
2
Our Sun Four Main Layers

• the corona
• the chromosphere
• the photosphere
• the core

3
Corona

• The corona is the outer most layer of our sun.
• Most scientist believe that it is about 1,700,000
  degrees Celsius in temperature.
• The corona is the bright halo that is still
  visible to us during a total eclipse.
• Scientist wait eagerly for solar eclipse to
  gather more information about our suns corona.

4
Chromosphere

• Moving inward from the Corona, the next layer of
  the sun is the Chromosphere.
• The Chromosphere is the layer that appears as a
  red disk when the sun is photographed.
• The Chromosphere is 27,800 degrees celcius.

5
Photosphere

• The Photosphere is the third layer of the sun as
  you move inward from the Chromosphere.
• This layer is 6000 degrees Celcius.

6
Core

• The Core is the inner most layer of the sun.
• It is about 15,000,000 degrees celcius.
• The Core is presently the site of most of the
  nuclear fusion that is producing energy on our
  sun.

7

• From studying our sun and exploring its various
  layers, astronomers can better understand the
  other stars in our universe.
