It does. Or rather, it will. It just hasn't yet, and is not expected to burn out until
a few more billion years from now, because it has that much fuel remaining.
Our sun is estimated to be about halfway through it's normal lifespan now.
"Never" is a big word... The Sun has shone for a long time, and it will continue shining for a long time, but it will eventually run out of fuel.

In the center of the sun, hydrogen nuclei (protons) are at extreme density and temperature. When the atoms combine, they create helium, a fusion reaction that converts some of the mass to energy. The energy created by the various self-sustaining processes (called stellar nucleogenesis) slowly makes its way to the surface of the Sun where it is continually released as light and heat.
Gravity compresses the Sun, and other stars, to a high density, and at a high temperature. This causes hydrogen-1 to convert (via a process called nuclear fusion) to helium-4; this process releases a lot of energy.
It does NOT burn. The Sun is so hot, about 5500 Celsius at the surface and 16 million at the core that only gas and hotter states of matter can exist there.
There is no flammable material there and if you know, 98% of gas there are hydrogen and helium, so there isn't enough oxygen there for things to burn.
So how does it shine?
Deuterium and Tritium Hydrogen Atoms, those found in hydrogen bombs, merge to form helium, an energetic neutron and energy in the source of light and heat.
So many reactions take place that the sun is converting 4 billion tonnes of hydrogen into helium and vast amounts of energy every second, sending vast amounts of light, heat over the 15 billion kilometer journey from the sun right to earth.
Hope I helped.

The sun shines via nuclear fusion. Hydrogen combines with itself to form deuterium--the helium nucleus. This nucleus has a smaller mass than its individual components, and this mass difference or "defect" is liberated as energy. It takes tremendous heat and pressure to sustain this nuclear reaction, which occurs deep within the core of our sun--and any other star.
The sun derives its energy from nuclear fusion reactions that transform, in its nucleus, hydrogen into helium. The photons are released from the sun's core because of these reactions. It takes from 10 000 to 170 000 years for the photons to reach the sun's surface. Some of these photons are in form of light. Some photons releases thermal radiation. It takes eight minutes to light to travel from the sun to the Earth.
first of all the is here to keep you warm or you would freeze to death and second of all the sun gives you 70% of life
At present it is the thermonuclear fusion of hydrogen atoms into those of helium.
The surface of the sun is 5780 K.
There is small portion of oxygen about 0.77% in the Sun. Additional tip for clarification: Sun didn't burn with oxygen, this ball of fire burn from nuclear fusion reaction.
Ultraviolet light from the sun can cause skin cancer if you are exposed to enough of it for a sufficiently long time. If untreated, skin cancer can be fatal. Staring directly at the sun can cause permanent or temporary blindness, depending upon circumstances.
No. The sun will live for about a billion years more.
cold is bad for health because our body needs hot and it is cold
Yes you can. It is very hot and sunny there most of the time.
yes no matter what you are you get a sun burn
Put some tea on the sun burn so it keeps it from blistering and then put some aloe lotion on the sun burn and in a few days the sun burn should be gone.
Right here on earth! What do you think a "sun burn" is?
Burn Back the Sun was created in 2006.
The answer to your question is yes you can het sun burn from reflections of snow, but its a combination of the sun and the reflection that gives you the sun burn. sun light is sun light yes uv light is reflected and will burn you
Trying to Burn the Sun was created in 1975-01.
The sun fuses hydrogen in its core. It does not burn it in the sense we are familiar with.
you have to stay here on Earth have you ever hear of a sun burn.
Sun Burn itch is when you have a sunburn and it starts to itch badly.
stay out of the sun
No, Creepers do not burn, the sun burns undead such as Zombies and Skeletons.
