How hot does the sun burn?
Surface temperature on the Sun is more than 10,000 Degrees F. Inside the core of the Sun where the nuclear fusion is taking place, it is estimated that the temperatures reach into the Millions of Degrees F. The burning you mention is not actually burning as we know it. There is no flame from some material being oxidized. There is no remaining ash from the end of the fire…like on Earth. There is a nuclear fusion reaction going on which is converting Hydrogen Gas into Helium Gas. The process is something like that process going on inside of a nuclear power plant, except much, much larger and working on Hydrogen instead of plutonium.
