Question

why supernova can't occur with our sun ☀.

(unexpected answer: sun is a dwarf star) ,I already know it but what is the theory.​

Answer 1

Explanation:

Astronomers believe that our star, the Sun, is not massive enough to become a supernova. Instead, in about 5 billion years it should dramatically expand to become a red giant and will fry the Earth in that way. It's less dramatic than with a supernova, but the Earth will eventually.. be destroyed

Answer 2

Explanation:

Our sun, for example, doesn't have enough mass to explode as a supernova (though the news for Earth still isn't good, because once the sun runs out of its nuclear fuel, perhaps in a couple billion years, it will swell into a red giant that will likely vaporize our world, before gradually cooling into a white dwarf).
