      Earth is predicted to end when our sun’s lifetime is up, which is in about 7.5 billion years, when it balloons into a red giant engulfing our solar system.

      Life is predicted to end much sooner than that though – in around 600 million years when our atmosphere is likely to change because of the increasing energy of the sun which will kill plants, and therefore all other life that relies on oxygen.

      Or a meteorite could hit earth instead…..
