What determines how long a star will live?

Answer 1

Kinds of 'fuel' and the mass and the stars determines how it dies. If it is large enough, it will create a Neutron Star or a Black Hole; if it is some size close to our sun, it will become dwarf planets.

Answer 2

Mainly its mass. A massive star will get hotter and use up its fuel much faster. The most massive stars only live for a very short time - like a few million years. A star the size of our Sun can live a few billion years, and a red dwarf - which has quite a bit less mass than our Sun - can live some trillion years - quite a difference!

Answer 3

The mass of a star is the primary factor that determines how long it will live. More massive stars burn through their fuel more quickly and have shorter lifespans, while less massive stars can burn for billions of years. Other factors such as composition, pressure, and temperature also play a role.

Answer 4

What determines how long a star will live is on the star's mass.

Answer 5

The lifetime of a star is determined by the star's mass.

Answer 6

A star's mass determines the star's place on the main sequence and how long it will stay there.

Answer 7

It's initial mass

Answer 8

It's mass
