Will the Sun Become a Black Hole?

💡 The Answer

• No, the Sun is too small to become a black hole; it will end as a white dwarf.
• After exhausting its hydrogen, it will swell into a red giant and then shed its outer layers as a planetary nebula.
• The remaining core, about the size of Earth, will be a white dwarf made mostly of carbon and oxygen.
• A star needs at least 20 times the Sun's mass to collapse into a black hole.
