Something like five billion years more.

∙ 11y agoNo star will EVER convert ALL of the hydrogen to helium via nuclear fusion (the process that powers the star) because when the star is less than about 50% hydrogen, the helium gets in the way of the fusion reaction and the star begins to die out. The star will begin to shrink as the star's own gravity now is more powerful than the nuclear reaction, and the star will get more dense and will heat up.
If the internal temperature and pressure gets high enough, the star will begin fusing helium into even heavier elements, becoming a red giant.
The speed of this reaction depends on the original mass of the star.

In the fusion reaction on the sun what happens to hydrogen that does not convert into helium?
It just stays there waiting to be used-the sun has enough to last many billions of years and luckily for us the rate of burning has stayed fairly constant so far, but eventually it will run out of hydrogen and die.

How many more years worth of hydrogen does the sun have left?
Approximately 5 billion years left
How many times longer does a 1.5-M star fuse hydrogen in its core than a 15-M star?
200 times longer
Why is Jupiter a gas planet?
Jupiter is a gas planet. it has no solid surface. Instead, the planet has a small, rocky core surrounding by immense layers of gas. Jupiter is gas because its mostly made out of hydrogen and helium.It just is...?Because it is made up of many different gases like hydrogen,heulim.
How many years will the hydrogen in the suns core last?
millions of years
How many years will the hydrogen in the sun's core last?
1 billion years
How many protons in a atom core?
that depends on which element it is. Hydrogen has 1. Uranium has 92.
How many feet is it through the Earth's core?
about 6370km from the earths surface,convert now to feet

Why does the sun not run out of hydrogen?
It will eventually. In about 5 billion years the sun will deplete the hydrogen at its core. Afterward it will continue to alternate between fusing helium in the core and fusing hydrogen in a shell around the core before it finally dies.
How many years is one million minutes?
Divide the number of minutes by 60 to convert to hours, then divide the result by 24 to convert to days, and finally divide that by 365.25 to convert to years.

Will the sun ever go out AND WHY?
Yes. The sun is powered by nuclear fusion as it converts hydrogen into helium in its core. This hydrogen will run out in about 5 billion years. It will expand to many times its original size before contracting again and fusing helium. After that it will shed its outer layers and leave behind a small remnant called a white dwarf.
Can a car run on hydrogen and why?
yes but the idea was lost many years ago
