When a wood or plastic burns, smoke comes out of it and we can see it but we are not able to see the smoke of sun. Why?

The Sun doesn't put off smoke.It is a ball of gas. It is not burning any thing.

When you have a wood fire, or burn other complex materials such as paper or leaves, this is a chemical reaction. The carbon in the material is combining with the oxygen in the air to make carbon dioxide.

Materials left over from the chemical reaction (including unburnt carbon) are left behind as ash. Some of the ash being generated by the fire is very fine and is carried away in the convection currents generated in the air by the heat of the reaction. This is the smoke that you see. It's basically a finer powder of the same ashes that fall to the bottom of your charcoal grill or your fireplace.

The sun is not a chemical fire where atoms and molecules break electronic bonds and make new ones. Hydrogen nuclei are being slammed together because the heat of the sun makes them move so fast that the natural repulsive forces of nuclei are not strong enough to keep them apart. When they collide, this creates a helium nucleus - an entirely different element.

This helium is heavier than the hydrogen, so most of it finds its way to the center of the sun, where it will remain until the hydrogen is depleted. At this point, the sun will momentarily condense, heating itself further until the hydrogen begins fusing into heavier elements such as oxygen, etc....

There's no ash being left behind in this process, and it's not escaping due to convection, which is why there is no smoke.

You see smoke due to oxygen from the wood or plastic burning. I am fairly sure there is no oxygen in the vacuum of space. The sun does not "burn" the way regular materials burn here on earth. Plus, the sun is too bright to look at it with the naked eye. Plus...I'm almost sure that the flares and solar winds generated from the sun's production can be perceived as "smoke-like action".

wood and plastic mainly consists of carbon and hydrogen molecules , In presence of Oxygen If it gets ignited and catches fire .Its an exothermic reaction is a chemical reaction whereby heat and energy are released as a substance changes to a more stable chemical form (in the case of fire, usually generating carbon dioxide and water). These co2 molecules are released as fumes or gases.

Rather than this exothermic reaction , In the solar system i.e., Sun , the nuclear fusion reaction takes place which is the process of spontaneous stimulation of stable nucleus to an unstable one.And this process is uncontrollable due to triggering of further photons.The fusion of two nuclei lighter than iron or nickel generally releases energy .the hydrogen atoms are trigered to helium atoms which is more stable and it releases huge amount of energy as heat and light without any smoke.

The sun is not wood or plastic. Nor is it on fire. The sun is a giant nuclear fusion reaction.

All the people who are saying "it's too far away" or "the sun is too bright" are joking, aren't they? Seriously, aren't we taught in something like the fifth grade that the reaction that goes on in the sun is not chemical combustion?

Because we are not looking at a carbon-based fire.
The sun is nuclear fusion, turning hydrogen into helium.
There is debris, in the form of a solar wind.
But that is particles which are caught by magnetic fields.
We see this in the form of northern lights, aurora borealis.

The problem, dear Spibbles, is that it was necessary for them to be paying attention in the fifth grade.

Fortunately, when social systems break down because of the spread of ignorance and greed, the people who paid attention in the fifth grade will end up ruling the world.

well, ther might not be smoke cuz theres no air in space, thats just a guess but a better answer is the suns really far away and to see somthing as transparant as smoke through the atmosphere all those millions of miles away would be hard if ther is smoke. im not an expert this is just my rational...

Edit: oh yea 2 thumbs down cuz i try to guess an help somone with a question real mature, i do best in english yet when i go out of my way to help somone, even if its not a serious question i get demoted cuz some science major outta colledge decides he dosent like my obviously 1 highschool year educated guess yea the smart fifth graders really know how to be mature dont they?
yes we are taught that it is a reaction of nuclear fusion however asking people to now that that isnt a chemical reaction based on what they learned in fifth grade is a little bloated. i could have recited the text book answer of what goes on in the sun however i couldn't have told u the whole its not a chemical reaction thing cuz teachers dont go as fas to tell u that much cuz it isnt gonna help u pass the state required tests usually halfway to the end of the year or a little later. in fact majority are just going to get confused i ve lived in 4 states gone to 7 different schools and i still cant tell u that, and i know im not stupid cuz im in governers school where they only let like 30 kids in out of the tricounty are in, yes im sort of bragging but to make a point that the average person, especially someone not in college or majoring in science isn't really gonna know that unless ur like this kid i go to school with who wants to spend a two year project on somthing as boring as the hundred year war instead of somthing you enjoy just to impress teachers...

because the sun doesn't burn
it goes through nuclear fusion- a process that's very very powerful and releases alot of energy. the scientists in wwii tried to discover how to make it happen, but they could only figure out nuclear fission.

Smoke is caused by incomplete burning.
