How long will it take for our sun to turn into a white dwarf?

Report as

According to scientists, our sun will turn into a white dwarf in 4.5 millions years to come. They predict that this is when the supply of hydrogen will run out in the core. After evolving through the hydrogen-burning phase, the Sun will puff up into a huge red giant star as the hydrogen fuel becomes scarce.

It's 4,5 billion years. So we still have a bit more time move somewhere else. ;-)

I heard the sun doesn't burn out until another 500,000 years
