What does the sun consume to produce energy and helium?

Sun consumes Hydrogen to produce energy

Explanation:

Sun is a huge sphere of hydrogen gas in which hydrogen gas nuclei combines and forms helium nuclei by nuclear fusion reaction.

This is also known given as

so here when these two isotopes of hydrogen combines and gives helium nuclei then in this reaction the energy is released and due to this nuclear energy released the sun will get energy to consume and to give high temperature.

the working equation for the angular size is the product of the physical size and 360 degrees divided by the product of two pi and distance from earth. the minimum size would be 0.559 degrees while the maximum size would be 0.49 degrees.
