>The sun only has 2.4 billion years left
According to this[1], you're off by a few billions years. The sun has enough hydrogen to burn for another 5 and a half billion years. After that, it has enough helium to burn for another billion years.

- debt 12y agoYeah but the Earth will be unable to sustain itself during the end of the Sun's life. Maybe I should say the Earth has 2.4 billion years left, not the Sun.
- bashinator 12y agoYes, but the sun is also getting hotter over time. This will push the habitable zone past Earth's orbit in somewhat less than two billion years[1]. [1]http://online.liebertpub.com/doi/abs/10.1089/ast.2012.0938 http://online.liebertpub.com/doi/abs/10.1089/ast.2012.0938
