The sun uses a very efficient process of nuclear fusion to convert the bulk of its material, hydrogen, into helium. Once the hydrogen is gone, the sun will turn into a red giant and expand almost to where the earth is at this point. The sun has about 5 billion years before the hydrogen is burned out so you have nothing to worry about. This was a very basic summary. Read more here:

The sun uses the process of nuclear fusion to produce visible, infra-red waves. The infra-red are sort of ‘heat’ waves and help to keep the surface temperature of the Earth warm enough for organisms like us and animals, plants etc, to survive.

Sun's major's role is 2 attract all the planets ,ofcourse it is the universal gravitation law ,it produces lots of energy by nuclear fusion

Fusion allover..
.
neutrino emission too is an activity....
hydrogen to helium produces heat it is an activity..
in core more heavy fusions occur...ex..helium to carbon.
It bends space-time and thus compel earth and other planets..objects to revolute around it..
It do rotate around milky way's centre
