What is the surface area of the Sun's corona? How many joules is the Corona producing?
The corona is high temperature plasma of over a million degrees. How much surface area is emitting energy from the Corona?
If the sun generates 4 x 10^33 ergs per second converting 4 x 10^12 grams per second of hydrogen in helium and energy?
How fast is the mass of the sun decreasing? As the sun mass decreases does it energy production decrease also?
How much energy is being emitted from one square meter of the corona and how many square meters does the corona approximately cover?

The Surface area of the Sun is 6.0877×1018 m2 which is 11,990 times of Earth's.

However considering the Corona, it produces nearly 1kilowatt for every square meter or 1/40000 of the light energy emitted from the sun.

Therefor the Corona produces like 6.0877×1018 m2 KW of energy by the Corona.
Hope this helps !

Sorry. It has to be changed to 10^18 from 1018 :-)
Will convert the value into joules and btu, also
