In about 6 or 7 billioin years our sunh will become a red giant and swallow up the inner planets.
After this… and I’m not sure exactly how long after… the sun will become a white dwarf… shedding its outer layers. The graviational pull on the outer planets will be less, so the outer planets will start driting out through the solar system. When they hit the asteroid belt, everything will probably get shredded.
They’ll last as long as the Sun does, which is another 5 billion years before it becomes a red giant. The outer planets like uranus and nepture may even survive this in some form.

So does Neptune survive and stay out in the open?
