How long do massive stars live?

Answer 1

Alexander Acosta

Less than a few million years...

A star's life span is determined by its mass.

Because they burn hydrogen (fusion) more slowly than massive stars, smaller stars have much longer lives.

However, massive stars have a shorter lifespan than smaller stars due to their rapid fuel burning.

The fuel can be burned for up to 10 billion years by our Sun, a medium-sized star.

The exact lifespan of a massive star depends on its mass, but generally speaking, they undergo fusion at a much faster rate, leading to shorter lifespans. Massive stars typically live for only a few million years, which is much shorter than smaller stars like the Sun, which can live for billions of years.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
