Comment Comment by chasil Our sun does not have an iron core. If it did, it would immediately collapse into a black hole.When the sun burns all of the hydrogen in the core, it will then burn helium. The burning will end at carbon.https://en.m.wikipedia.org/wiki/Carbon-burning_processSilicon burns to iron, which becomes degenerate matter that cannot resist gravitational collapse. parent chasil 2 years ago
