Question: How long does it take for a star to die from when it was born.

It depends how massive the star is! From when a star is born, how much mass it has determines its trajectory in life, whether it’ll become a black dwarf or collapse into a black hole. Stars like our sun will live for about 10 billion years! Bigger stars are more unstable so they won’t live for as long as smaller stars but they’re all in the range of millions of years. So a long long time…
