Question

why sun is shining,sun is far from Earth ​

Answer 1

Resposta:

the sun is a star and stars shine because they are extremely hot (which is why fire gives off light — because it is hot). The source of their energy is nuclear reactions going on deep inside the stars. In most stars, like our sun, hydrogen is being converted into helium, a process which gives off energy that heats the star.
