How hot is the sun?

Question

Heat wise

Answer 1

The surface of the sun is 5780 K (6053 C, 10,930 F). This is the temperature needed for the surface to radiate the heat and light that we can detect (63.2 million Watts per square metre).
6.092 million million million square metres
(called trillions in Europe, quintillions in USA)
Total output = 3.85 x 10^26 Watts

The energy is not produced at the surface. It is produced in the core where the temperature is somewhere around 14 million degrees K (24 million F). At that temperature, and at the pressure and density that exists there, the hydrogen atoms are moving around so fast that they smash into each other (despite nuclear repulsion) and fusion occurs.

It is the fusion energy that eventually gets carried to the surface where, by the time it gets there, it is down to a bit below 6000 K.

Answer 2

extremely hot, heat wise. About 5800 K. imagine every square millimeter of the suns surface radiating more energy than a 60 watt lightbulb.

Answer 3

The surface temperature is 10.000 degrees C. The core is millions of degrees.

Answer 4

really hot

Answer 5

very.
