Solar - Corona

We've learned about the Sun's core, radiation zone, convection zone and photosphere.
The area outside the surface of the sun is called the corona which comes from the word crown.

Even though the corona is outside the surface of the sun, it is even hotter than the surface!
The photosphere surface is about 10,000 degrees F, and the corona is over 5,000,000 degrees F.
