The light that we see is the result of Nuclear fusion, which emits photons during the fusion process. Unlike a fire which releases light, heat and other radiation by chemical reactions (the rapid breaking apart of molecules), the energy of suns is produced by fusing elements (mostly hydrogen) together and releasing MUCH more energy. A nuclear bomb works on the same mechanism, using powerful explosives directed inward to cause nuclear fusion. In the sun the force that causes nuclear fusion is the intense pressure of the sun's gravity.
The light from the sun comes from millions of nuclear reactions happening very rapidly in it's core, the only reason our sun won't explode is it's powerful gravitational field holding back the most powerful force imaginable.

∙ 12y agoStars appear as points of light to us because of their long distance from the earth which has to be measured in light years&each light year is 10 trillion kilometers which is really a long distance
Wiki User
∙ 12y agoIt's because we are very, very, very distant (far away) ,that can be long as space which is endless according to scientists, from the stars. In space they are actually very, very, very large. The far away effect looks like they are so small since the stars can be even 20 billion light years away. If you want to see it closer up try using a telescope or go to an observatory to look at the stars.

Why they are hot is another question [See related question]

∙ 13y agoThey look so small because they are so far away from us they seem smaller then they really are.
If you were to go up close to a star it would be huge!

the stars emitt its own light. But the planets do not have any own light. It absorbs the light from the stars like a sun. It just reflects the light. And also the stars are far away from the earth than the planets. So we can found the twinkling of stars but not the planets.
