What is the process of nuclear fusion as if occurs in the Sun?

Nuclear fusion is the process in which two lighter nuclei ( hydrogen nuclei here) combines to form a larger nuclei( helium nuclei)…. it releases or absorbs a large amount of energy in the process…substances above iron in the periodic table absorbs and the ones below liberates energy… In our sun hydrogen is in plenty and the conditions are just optimum for the fusion reaction…so there two hydrogen nuclei combine to give a helium nuclei which is more stable than the hydrogen nuclei and hence liberates a tremendous lot of energy…of the order of MeVs…(about 17.6 MeV for a single reaction)…millions of reactions like this takes place in the sun simultaneously resulting in the enormous amount of energy released by the sun… For artificially creating a fusion reaction we need very high temperatures of the order of 10^7 kelvins…so normally a fission reaction is carried out first to obtain the suitable conditions for the fusion reaction to take place….. Hope this helped…
