It depends a lot on the mass of the star. It can be anywhere between a few million years (for the most massive stars), to tens of trillions of years (for red dwarves).

What determines the path a star will take during its lifetime?
The mass of the star
What is a star's main fuel during its lifetime?
hydrogen
If The light you see from the North Star was emitted in 1583 and takes 430 light years to get to earth does that mean it should be burning out soon?
No. A few hundred years is insignificant in the lifetime of a star. Even the shortest-live stars last for millions of years. Polaris is a three star system. The main star, Polaris A will probably last for another few tens of millions of years while the other tow stars will last for another few billion years.
Is the main sequence lifetime of a low mass star the same as the lifetime of the sun?
No. The less massive a star, the longer it will last. A main sequence star half the mass of the sun can be expected to last about 5 times longer.
What is the temperature range of a white star?
A white star has a temperature range of between 7,500-10,000 K. A blue white star has an even higher temperature range, and a blue star has the highest.
What is the range of lifetime for stars?
Lifetimes range from a few million to 100 trillion years
How long does an massive star live?
The lifetime of a star varies a lot, depending on its exact mass. The lifetime of a star can be anywhere from just a few million years for the most massive stars, to trillions of years for red dwarves.
The star 61 cygni B has a main sequence lifetime of about how many years?
10¹¹ years
The main squence lifetime of an O star compared with an M star?
An O star will stay on the main sequence for millions of years whereas a M star can stay on the main sequence for billions and billions of years.
How does a star's mass indicate lifetime?
When a star is at the end of its lifetime its mass increases.
What is the timescale for the cycle of a star?
The lifetime of a star may be anything between about a million years for the more massive stars, and several trillion (several million million) years for red dwarves.
How is the lifetime of a star comparable to stellar evolution?
Stellar evolution is the term for the changes a star undergoes during its lifetime.
How many years does a star lives?
It depends on the size. Small, dim stars live much, much longer than large, bright ones. The expected lifetime of a star like the Sun as a main-sequence star is about 10 billion years.
How does a stars mass indicate its lifetime?
When a star is at the end of its lifetime its mass increases.
What determines the path a star will take during its lifetime?
The mass of the star
How long does a star like the sun last?
Our sun, or another star just like it (there are many more like our sun) has a lifetime of about 10 billion years, give or take 500 million.
How far is centaurus from earth?
About 4.3 light years, assuming you refer to the Centauri triple star system. About 150,000 years away by Space Shuttle. :-) if you're looking for a range, from the nearest star to the furthest star, it's about 4.2-525 light years away.
