What happens in 7.6 billion years time?

Well, according to these articles arising from work done at Sussex Uni our sun will have swollen to a size greater than the Earth’s current orbit and swallowed it up.

No need to worry, though: life will already be gone long before then as the approaching surface of the sun boils the oceans away and blasts it into space on solar winds.

On the up side, however, the sun will lose mass during this process and its gravitational influence on our planet will be diminished. It is possible that this phenomenon, together with ‘nudges’ from passing asteroids, might allow the Earth to move further away from the sun – to increase the radius of its own orbit – and escape being engulfed.

But there still won’t be any oceans.
