Our sun is a fire ball in outer space and there is no oxigen in outer space, how does the fire keep burning?

Answer 1

It is not burning it's fuel in the manner you are familiar with. The sun does not burn gas or wood, which requires oxygen, as you are perhaps familiar with in gas grills or stoves, or bonfires.

Instead, the sun's "burning" is a process called nuclear fusion -- in which the heat and gravitational pressure combine (fuse) two atoms of hydrogen into one atom of helium. In the process of fusing the hydrogen into helium, immense quantities of energy are released.

Answer 2

The Sun is a massive nuclear reactor that radiates heat throughout our solar system from Mercury to Earth and to Pluto (and possibly a 10th planet past Pluto). The distance of our Sun to the Earth is approximately 92,000,000 miles or 149,597,687km. The approximate mean distance between the the Sun and the Earth is 149,597,870 AU. AU stands for Astronomical Units and is defined as the average (or mean) distance from the Sun's center to the average of the Earth's menter.

The light and thus the heat we receive from the Sun travels at the seed of light which is:
- 186,282 miles per second
- 670,616,629 miles per hour
OR
- 299,792,458 km per second
- 1,079,252,848 km per hour

There is no OXIGEN listed on the The Periodic Table of Elements. However OXYGEN is listed on chart as Element #8. The sun will keep burning for a very, very long

Answer 3

Because it isn't a fire ball. It isn't a fire. At least a chemical combustion fire anyway.
The sun undergoes a nuclear fusion reaction. Actually, a series of reactions, but the net overall sum of things is that hydrogen is fused together in a nuclear reaction to produce helium. There is a LOT of energy released when this happens, so there is plenty of nuclear fuel for a very long time.

Answer 4

Dave_Stark has the best answer so far. Please disregard any ideas of the sun having an oxygen atmosphere, or there bieng a loop of fission-fussion processes. Fission does not occur in the sun, it never occurs spontaneously.

Also, it should be noted that the "fire" you observe is really super-hot plasma gases. The hydrogen gets SO hot that it's electrons dissociate from the atom. The net movement of ALL the electrons from ALL the atoms in the sun causes the immense, bright glow that you see, and in addition, they are the root cause of most of the magnetic phenomena observed in the sun (sun spots and solar flares, for instance).

Answer 5

It's not really "fire". There is a mixture of certain chemicals that cause constant interactions and create the effect of "fire". What is happening is that these constant chemical reactions emulate "fire". The chemicals created are "released" and we feel their heat, thereby, giving yet another effect as if it might be "fire" that is going on. The process is on going and the effect seem to be lasting forever - however scientists think that the effect will eventually stop and the "sun" will emplode! Millions of years from now there will be no more "sun".

Answer 6

The "burning" that you are observing is actualy a complicated process of nuclear fusion. I dont quite understand it fully but from what I know the sun has a fuel source of hydrogen and through a nuclear reaction changes this into helium. Thats the " burning you see.

Answer 7

The sun is a natural nuclear fusion reactor. It is self-sufficient, as the fusion process creates burnable material, and the burning of that material sustains the fusion process. The sun is more likely to expand and destroy the earth than it is to burn itself out.

Fusion releases astronomically more energy than fission, which is used in nuclear reactors and weapons. Interestingly, if we can learn to duplicate and to truly control the fusion process without burning ourselves up (the biggest by-product of fusion is heat, then we'll have enough energy to power the entire planet!

Answer 8

Yes, this is true that for burning of fuel, oxygen is required. Oxygen is created by sun itself for burning hydrogen and helium fuel. You have ever noticed that a lava is burning inside the earth. Is oxygen gas is present inside the earth or not? Yes, oxygen is present. co gas will come out from earth when burning lava. oxygen is the supporter of combustion process.

Answer 9

Hydrogen is burned in the core and is already ignited from the birth of the star. Then the helium is sent out in space. So it is not the oxygen that is ignited but the hydrogen.

Answer 10

Because i think that the sun has a fuel source in it that keeps it burning, like when we use a oxygen tank to breathe under water
