What Will Happen to Earth in 5 Billion Years? Discover the Shocking Future of Sun
If Earth avoids this, it will be much cooler, like KMT-2020-BLG-0414.

In about five billion years, our sun will run out of fuel and change into a white dwarf.
Before that, it will grow into a red giant and might swallow up Mercury, Venus, and maybe even Earth and Mars.
If Earth avoids this, it will be much cooler, like KMT-2020-BLG-0414.
Stars shine for a long time by using hydrogen and helium. When they run out of hydrogen, they start using helium, which makes them bigger and turns them into red giants. This can cause them to take in nearby planets.
In 2020, astronomers found a special system near the middle of the Milky Way.
They discovered a brown dwarf and a planet twice the size of Earth using a method called gravitational lensing.
Scientists aren’t sure if life can exist when the sun is a red giant, but some think that people might find a home on icy moons like Europa and Enceladus.
These moons could become water worlds as the sun gets bigger.
