What will happen in the next 5 billion years?
But that’s not all. Beginning around 5 billion years from now, the Sun will expand, becoming a swollen star called a red giant. By 7.5 billion years in the future, its surface will be past where Earth’s orbit is now. So the expanding Sun will engulf, and destroy, the Earth.

Earth. While the sun may have 5 billion years left before it runs out of fuel, life on Earth will likely be wiped out long before that happens. And, when the sun does turn into a red giant, the Earth will also be vaporized — perhaps just a few million years after Mercury and Venus have been consumed.
