By mass . The smaller the star the longer it shines. Stars that are 20 times the mass of the sun only last 10 million years or so but will be thousands of times brighter than our sun. Our sun will shine for 10 billion years (it is about half way through it's life). Small stars called red dwarfs less than a tenth of the suns mass may shine for a trillion years or more but will be less than 1/100 of our sun's brightness.

What is the most important characteristic in determining the length of a stars life?
The most important characteristic in determining the length of a star's life is its mass. More massive stars burn through their fuel more quickly and have shorter lifespans, while less massive stars can burn for billions of years.
Is it true that the length of a stars life depends mainly on its temperature?
Yes (and its temperature depends on its size), the bigger (and hotter) the shorter its life.
How do scientists determine the chemical makeup of the stars?
Different chemicals emit and absorb light at various wavelengths. Astronomers can look at the wavelength of light coming from stars and determine which chemicals must be present.
Are red stars old or new?
The color of a star does not directly determine its age. Red stars are large and a little less hot then the Sun. Scientists can use the color of a star to determine its heat and then using that and its mass determine how old it is.
The light from stars are used to determine what?
The light from stars can tell us what type of star it is (our Sun is a G type), the stars spectrum can tell us what elements are in the star, and its intristic brightness can help us determine how far away it is. Also, if there is a wobble in the star, or a change it the stars brightness can tell us if it has a planet.
Do stars determine the life ahead of you?
maybe, but I'm no expert in astrology.
What are the factors that determine the length of an engagement?

What is role of historical data in life insurance?
Data on the length of life is used to create a statistical model of how long people live. That is used to determine the mortality tables which determine the insurance company's prices.
What are Binary stars used to determine?
The masses of the two stars.
The length of a stars life cycle?
That would be its size. Bigger stars live shorter lives because they use up energy faster, while smaller stars live longer because they don't use up as much energy.
What determines how bright stars are?
Size and temperature determine the brightness of stars.
What is the most important characteristic in determining the length of a stars life?
The most important characteristic in determining the length of a star's life is its mass. More massive stars burn through their fuel more quickly and have shorter lifespans, while less massive stars can burn for billions of years.
What is this improved the ability to determine latitude and longitude based on the altitude of stars?

How do you determine the length and width?
measure it
Is it true that the length of a stars life depends mainly on its temperature?
Yes (and its temperature depends on its size), the bigger (and hotter) the shorter its life.
What is the length of a rectangle that its perimeter is 30?
The perimeter of a rectangle is not sufficient to determine its length.
Why does the short length of pulsar pulses eliminate normal stars as possible pulsars?
The short length of pulsar pulses eliminate normal stars as possible pulsars because normal stars do not have strong enough magnetic fields.
