Best Answer

The sun would then be dead, and the solar system including all the planets would receive no more energy from the sun. Life on Earth would die out.

More Info:

It is thought that the sun is not large enough to fuse carbon into iron. It turns out it should fuse all of the helium and finally end leaving nothing but carbon. In fact, our sun will turn into a dwarf star which will resemble basically a planet sized diamond.

Stars that produce iron through fusion are usually much larger and produce supernovas. The heavy gravitational pull uses excess energy to fuse iron into the larger and more rare elements before blowing the entire star and core apart. This is how these heavy elements exist around the universe.

What is events of occurring in the sun?

Nuclear fusion: mainly of hydrogen into helium. To a lesser extent there is fusion of helium into larger elements - all the way to iron.


What does nuclear fusion cause?

Nuclear fusion, which is the mechanism by which stars operate, will cause lighter nuclei to "combine" (fuse) to create heavier ones. It will also cause a lot of energy to appear. This is because the fusion reactions are exothermic (at least through fusion that creates elements up through iron).
