    The sun will never explode. In a few billion years it will puff up to a red giant with a circumference somewhere around the orbit of earth or mars when it starts burning helium. After the helium runs out it will lose the outer layers and become a stellar remnant called a white dwarf. It’ll stay that way til it fades to darkness in a few hundred billion years. At no point will it explode as it doesn’t have enough mass to explode.
