Theoretically, in 5 billion years, the Sun will still be in the main sequence. 5.4 billion years (estimated) marks the end of main sequence, where it will be in the intermediary point between a main-sequence star and a post-main-sequence red giant, where it will slowly reach over 200 times it's current mass over the course of about a billion more years, at which point it would be classified as an official red giant and be fully burning helium-4 as a main source of fuel as well as burning a hydrogen shell it built up during the main-sequence.
After that point it will eject most of its mass into a planetary nebula and slowly cool as a stellar remnant over the course of a few quadrillion years until it reaches 3K.

What is the sun's lifetime in years?
The sun is estimated to have a total lifetime of about 10 billion years. It is currently in its middle age, about 4.6 billion years old, and is expected to remain stable for another 5 billion years before entering its next phase.
What day is the suns birthday?
The sun "formed" at least 4.6 billion years ago, so it doesn't have a specific birthdate or day of creation.
How long will the suns hydrogen last in seconds?
Total time about 10 billion years = 3.1556926 × 1017 seconds
What stage of the suns life cycle will destroy the earth?
In about 5 billion years, the Sun will exhaust its nuclear fuel and expand into a red giant, engulfing and ultimately destroying the Earth. This will happen during the final stages of the Sun's life cycle when it runs out of hydrogen fuel in its core and transitions into a red giant star.
What is the next stage in the suns evolution?
The next stage in the Sun's evolution is the red giant phase. This occurs when the Sun runs out of hydrogen fuel in its core and starts burning helium. During this phase, the Sun will expand and become larger, eventually engulfing Mercury, Venus, and possibly Earth.
What is the the next stage in the Suns evolution?
red giant
What is the sun's next stage?
The Suns next stage is to get hotter and slightly increase in size.In about 4.5 -> 5 billion years, it will have used up all of it's hydrogen, and will begin to fuse helium in it's core. Due to this, it's outer envelope will have expanded almost to the edge of the Earth.Don't worry - we will all be dead by then.After another billion years, the Sun will shed it's outer envelope as a planetary nebula and settle down to a retirement as a white dwarf for quite a few billions of years.
What will be the next stage in the suns life cycle?
The next stage in the sun's life cycle will be the red giant phase, where it will expand and become cooler. This will be followed by the shedding of its outer layers to form a planetary nebula, leaving behind a white dwarf at its core.
What is the suns total estimated life span?
10 billion years
Where dies the suns nuclear fusion occur?
In about 4 - 5 billion years. I'm pretty sure it's 4.4 billion years.
What is the sun's lifetime in years?
The sun is estimated to have a total lifetime of about 10 billion years. It is currently in its middle age, about 4.6 billion years old, and is expected to remain stable for another 5 billion years before entering its next phase.
When was Under a Billion Suns created?
Under a Billion Suns was created on 2006-03-07.
How many suns is needed to hold a billion earths?
One sun holds about 1,000,000 Earths. A billion is 1,000 millions so it would take about 1,000 suns to hold a billion Earths.
How long is the suns nuclear energy expected to last?
Roughly 6 billion more years. Then the sun will expand and eat the earth.
How many suns do you have in your soaler sysmtem?
In our solar system, we only have 1 sun. It will explode in like a billion years so then we will have no sun.
How many moons does the suns have?
there are about 5.3 billion suns in our solar system, each containing about 4 moons
Is it possible for the sun to get close to the earth?
Wait about 5 billion years and the Suns outer envelope may well touch the surface of the Earth.
