How many more years worth of hydrogen does the sun have left?

The sun has about 5 billion years worth of hydrogen left before it exhausts its supply and evolves into a red giant star.

It depends on the current year. Subtract the current year from 2112 to determine how many years are left until 2112. For example, if the current year is 2021, then there are 91 years left until 2112.


How long before the sun burns out?

The sun will not "burn out" in the sense of a fire burning out. It has about 5 billion years of life left before it will exhaust its hydrogen fuel and enter a phase of expansion as a red giant. After that, it will eventually collapse into a white dwarf.


Would it be possible to see the star Betelgeuse even if that star had died hundreds of years ago?

When we look at stars, we are seeing the light that they are emitting. That light could have left them many years ago. The light from Betelgeuse takes over 640 years to reach us. So if it exploded today, we would not see that explosion for over 640 years. So it is possible that it is already gone, but the light that left before it went is still coming towards us.


Will the sun ever fail?

The Sun is 4.6 billion years old and about halfway through the phase where is shines as it does now due to fusion reactions that convert hydrogen into helium. The Sun will continue this phase, with some variability, until it is about 10 billion years years old. About 5 billion years from now, the Sun will enter a red giant phase and expand greatly. This lasts for hundreds of millions of years before it blows off its outer layers creating a planetary nebula. In the next several billion years, what is left of the core of the sun will fade to a white dwarf and then continue to cool further forever. The Sun does not have enough mass to explode as a supernova.
