because the heat and energy comes from the fusion of hydrogen atoms into helium atoms and not from normal combustion (basically it's a continous nuclear explosion, except much worse). In fact, normal fire would never be hot enough to keep the earth habitable.

The pressure and temperature at the center of the sun is so imense that hydrogen atoms can get close enough to fuse into helium atoms. The total weight of the hydrogen atoms is slightly less than the weight of a helium atom they create. The lost mass (mass defect) is converted into a relatively large amount of heat energy per Einstein's equation E = mc2 (Energy equals mass times the speed of light, c, squared). it takes about a century for the newly created heat to reach the surface of the sun (which prevents it from cooling off!) and then it takes about 8 more minutes for the light created by that heat to reach your eyes on earth. We are always looking at 8 minute old sunlight that was actually generated 100 years ago.

Yes. The Sun is not on fire, and there is no "burning" happening there. The Sun is very hot - it gets its heat from the nuclear reactions that happen at its core, which keep it much hotter than it could be if it were burning.

The sun is like a continuously exploding H-bomb: it burns
by thermonuclear fusion reactions, that is, it emits energy
by fusing hydrogen nuclei into helium nuclei. Space doesn't have Oxygen, that's why airplanes can't fly into space and astronauts have to wear spacesuits.

The solar isn't hearth as all of us be responsive to it. it is not flame. this is a nuclear reaction or technique. fullyyt distinctive. ben of marlow mentioned it maximum suitable, i think of ("this is using fact the solar isn't "burning" interior the actual sense. the approach that retains the solar going isn't combustion. this is nuclear fusion - the nuclear of Hydrogen nuclei into Helium. No oxygen is needed for this.")

The sun is not on fire. It is a gigantic nuclear reaction that is giving off heat and just appears to be "fiery".

The sun is not actually 'On Fire", it's rather in a state of plasma discharge.

nuclear fusion in the core of the sun not combustion at its surface

it burns the hydrogen atoms and releases solar neutrinos

woah...i dont know. maybe its a different type of fire...good thing there no oxygen in the universe, it would burn up.
