Why will the sun never become a neutron star?

Answer 1

The Sun will never leave behind a stellar remnant such as a neutron star, as it does not have enough mass to achieve the massive pressures required to make one.

Our Sun will end up as a white dwarf stellar remnant.

Answer 2

The sun does not have enough mass to undergo a supernova explosion and collapse into a neutron star. Instead, it is expected to shed its outer layers and eventually become a white dwarf.
