No one is sure. When you look up at the stars, it is like looking at a picture that was taken billions of years ago. Though light travels very fast, it will take billions of years before we even notice the star has died. Dwarf stars like the Sun average 8 billion years supergiants average a few million years

That depends on the type of star.

A star like our sun is believed to have a life span of 10-12 billion years.

In general, the larger a star is, the faster it burns out. Large stars don't live more than a few billion years, while the smallest stars may burn for hundreds of billions of years.

billions of years

It varies, though depending on how large or small the star is when it forms.

Large stars have shorter lifetimes, in the hundreds of millions of years. Small stars have longer lifetimes, tens of billions of years. This seems contradictory, but what happens is that the centers of large stars are compressed more because of the large amount of gravity. This causes the nuclear reactions that power the stars to proceed much more rapidly. Hence, in spite of the greater amount of material in a large star, the large stars burn out more quickly.

The life span of a star like the Sun is about 10 billion years.

Higher mass stars don't last as long. They have more "fuel", but they use it more quickly.

So, the life span is based on a star's mass.

They can live anywhere from 10 million years to 200 billion years depending on thier mass. Stars like our Sun will live from 15 billion to 20 billion years.
