How long does a star live for?

Answer 1

the life san of stars is like if you had everyone bring in candles into the class,some would be round,some would be tall and skinney,and they all would go ot at different times.the round candles may take a lung time to go out, while tea lights may last only a short period of time.just like stars

Answer 2

The lifespan of a star depends on its mass. Typically, a star like our sun will live for about 10 billion years. More massive stars have shorter lifespans, while less massive stars can live for hundreds of billions of years.

Answer 3

a 40 solar mass star should live around 1,000,000 years
a 17 solar mass star should live around 10,000,000 years
a 7 solar mass star should live around 80,000,000 years
a 2 solar mass star should live around 2,000,000,000 years
a 1 solar mass star should live around 10,000,000,000 years
a .2 solar mass star should live around 500,000,000,000 years

Answer 4

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

Answer 5

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.

Answer 6

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.

Answer 7

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.

Answer 8

The life of a star can be tracked through a series of known paths.

Answer 9

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.

Answer 10

i'd have to say between 2 to 100 or 20 to 100 either or
