Earth has about 5 billion years left.
Explanation:
The lifespan of the earth is wholly dependent upon the aging of the sun. In about 5 to 6 billion years from now the sun is going to reach a point where its core can no longer sustain the nuclear fusion is has been and it will grow into a red giant. That means it is possible the sun could grow enough to engulf the earth itself but even if it doesn't, life will cease to exist on earth at some point during the sun's growth into a red giant.
