Over billions of years. On this scale, the details are blurry, but the overall picture is clear. The sun will continue to heat up and eventually undergo changes to its size and structure, producing a climate on Earth hot enough to evaporate the oceans and make life impossible. Eventually, the sun will shrink and start to fade, with the solar system reaching its cold “final configuration” in around 12 billion years.
