The Sun is about 4.6 billion years old and is estimated to have a total lifespan of about 10 billion years. It is currently in the middle of its main sequence phase where it is converting hydrogen into helium through nuclear fusion. It is expected to continue shining for another 5 billion years before evolving into a red giant and eventually a white dwarf.

Is our sun a middle aged star?
Our sun is just about in the middle of its lifespan. It will die in roughly 5 billion years.
How long would main sequence star last if twice as massive as the sun?
A main sequence star that is twice as massive as the sun would have a shorter lifespan than the sun. It would burn through its nuclear fuel more quickly and have a lifespan of about 5-6 billion years, compared to the sun's estimated lifespan of around 10 billion years.
If a star is twice as massive as the sun how will its lifespan compare?
The life expectancy of a star (E) depends on its mass (M), roughly following the model of E = M-2.5. For a star with a mass twice that of our sun (enter 2 in place of `M`), then the lifespan will give 0.177. Our suns lifespan is around 10 billion years, so this would equate to 1.77 billion years.
What is the sun's lifespan?
The sun is currently about halfway through its main sequence phase, which is expected to last about 10 billion years. It is currently about 4.6 billion years old, so it is estimated to have about 5 billion years left before it expands into a red giant and eventually becomes a white dwarf.
By Orion huddleston age 12 how old is the sun?
The sun is about 4.6 billion years old. It is roughly halfway through its life cycle, with an estimated total lifespan of about 9-10 billion years.
What is the lifespan of a star that is the size of the sun?
About the same as our Sun. About 10 billion years.

What is the lifespan of the Sun and it's fusion process?
um... the lifespan of the sun is 12 billion years, we are about half way to the 12 billion mark. (a little less). I think about 4.2 billion years old. The sun will engulf mercury and venus in the last 2 billion years of its life span, then it will either burn out or explode. If it has a higher mass, then it would explode then turn into a black hole! whopee...
How long will sun last for?
The Sun has been living for approximately 4.57 billion years , and is expected to last for roughly 5 billion more, as it's lifespan is about 10 billion years. :D
What is a unique cahracteristic of the sun?
One unique characteristic of the sun is that it is 109 times wider than the Earth. It has already reached its mid-point in its lifespan and will burn for 500 billion years more.
What is the average lifespan of a star in our solar system?
There is only one star in our solar system, the sun. It's due about another 5 billion years or so. The Sun is about half way through its life. Stars the size of the Sun (and the sun) live about 10 billion years.
When will the sun stop to shine?
The lifespan of the Sun is still in debate. Some say it will continue in its present state for millions of years to come - others say it will expand into a red giant in as little as 6,000 years !
