Celestial bodies heating particularly planets, brown dwarfs and Sun is mainly due to the gravitational contraction of their atmospheres. Gravitational contraction of the solar atmosphere is the Sun’s source of heating, which opinion at the end of the 19th century was proposed by Kelvin and Helmholtz. The solar heating occurs without any participation of nuclear fusion reactions.
