Does the sun change temperature?

Question

Does the sun change temperature?

Answer 1

Sunspots are hotter regions, but the temperature only varies on the surface.

Answer 2

The sun has spent the last 4 billion years or so burning a CNO fusion cycle at its core. For the next 4.5 billion years the sun will remain in this fusion cycle - known as a main sequence state. However, the overall energy output of the sun does gradually creep upwards as it ages. Thus, the surface temperature of the sun (currently 5730 K) will rise by a few tens of degrees over the next few million years!

Answer 3

Generally the outer surface of the sun is cooler than the inside layers of the sun.

Answer 4

as for now, it is not changing..

only the temperature of the surface with sun spots

because the sun spot area is usually cooler than the surrounding area

the sun will change temperature after a billion years from now

a change in color will indicate a change in temperature of the sun

Answer 5

No. Sunspots are cooler areas on the Sun but they don't significantly affect the amount of radiation that comes from it!
