Why doesn’t the sun burn, because it burns so much?

The sun does burn, but not in the same way that we think of burning here on Earth. The sun is composed primarily of hydrogen and helium, and it is held together by its own gravity. The sun is powered by nuclear fusion, which is a process in which two hydrogen atoms combine to form a helium atom, releasing a large amount of energy in the process. This process is what powers the sun and allows it to shine.

The reason why the sun does not "burn" in the same way that we think of burning here on Earth is because the sun is so massive that the outward pressure of its gravity is almost equal to the inward pressure of its fusion reactions. This balance of forces keeps the sun from collapsing in on itself and allows it to continue to shine.

The sun does not "burn" in the same way that we think of burning here on Earth because it does not require an external source of fuel, such as wood or coal, to keep burning. The sun is powered by its own nuclear fusion reactions and is able to sustain itself indefinitely.
