The size of the star is not as important as the class of the star. A star like the Sun which is classified Gv2, yellow dwarf, has a life span of about 10 to 12 billion years. The Sun is now 4.6 billion years old, which makes the Sun middle aged.
Alpha Centuari B is an Orange Dwarf about the same size as our sun, but is a Kv5 Star, has a life span of 15 to 30 billion years.
What else can I help you with?
Will a star twice the size as the sun have a longer or a short life span?
If a star is bigger than our sun. then it will have shorter life span than our sun.
Do Stars spend most of their life span as main-sequence stars?
Yes Star spend most of their life span as a main sequence star. A star end will depend on its size in life the end of a start can be a red giant to supernova, a white dwarf, pulsar, or black hole.
What is the life span of Rigel A star?
Rigel is a blue supergiant star that is estimated to have a lifespan of around 10 million years. It is currently in the later stages of its life cycle and is expected to end in a supernova explosion within the next few million years.
Which type of star has the longest life span?
A red dwarf.
How big is a 50 million year old star in the sky?
The size of a star does not change significantly over a span of 50 million years unless it is in a different stage of its life cycle. The size of a star in the sky is relative to its distance from Earth; so a 50 million year old star could appear as a tiny point of light or, if it is a particularly large star, it could be visibly larger in the sky.
Will a star twice the size as the sun have a longer or a short life span?
If a star is bigger than our sun. then it will have shorter life span than our sun.
How much bigger is the sun then a star?
the sun is a star. It is of medium size and life span for a star.
What determines all the star's properties such as its temperature size brightness or luminosity and life span?
It's Mass
How do you calculate life span of a star?
The life span of a star is determined by its mass. More massive stars burn through their fuel faster and have shorter life spans, while less massive stars have longer life spans. The life span of a star can be estimated using the mass-luminosity relation and the star's initial mass.
What is the life span of the star Rigel?
2.8 seconds
Do Stars spend most of their life span as main-sequence stars?
Yes Star spend most of their life span as a main sequence star. A star end will depend on its size in life the end of a start can be a red giant to supernova, a white dwarf, pulsar, or black hole.

Rigel is a blue supergiant star that is estimated to have a lifespan of around 10 million years. It is currently in the later stages of its life cycle and is expected to end in a supernova explosion within the next few million years.
Which type of star has the longest life span?
A red dwarf.
What is the life span of a yellow star?
Our sun is a yellow star, and its life span is roughly 9 billion years--on the main sequence. Smaller yellow stars would last longer, while larger ones would burn out faster.
How big is a 50 million year old star in the sky?
The size of a star does not change significantly over a span of 50 million years unless it is in a different stage of its life cycle. The size of a star in the sky is relative to its distance from Earth; so a 50 million year old star could appear as a tiny point of light or, if it is a particularly large star, it could be visibly larger in the sky.
What does the size of a star indicate?
It's temperature when on the main sequence.It's life span (Larget stars use their fule much more quickly)and in some cases (red giants) it's age.
What is the life span of a Star nosed mole?
I have no idea please some one answer this question
