This is interesting it's a star like our sun going red giant expanding into the orbits of the planets, some scientists wondered that when the sun goes red-giant if the orbits of the planets will push outward as the sun gets bigger, guess not.

Actually Earths end will come before the 5 Billion year mark, at around 3-4 billion years from today the sun will be so big, hot,& bloated that Earth will be more or less a charred cinder the oceans would of boiled away already. Then in another billion years the sun will likely engulf Earth, no one is sure how big the sun will get, but they do know that Mars will suddenly become warm and Titan the moon of Saturn will warm up- it's a hydro-carbon world with oceans of liquid methane & some ethane the warm up will turn those liquid oceans into a gas - the moons of Jupiter will also get warm, one of Jupiter's moons is believed to have a ocean of liquid water under it's ice, that ice will thaw out.
However 5 Billon years is really an eternity, humans can't really imagine that big of a time frame, the universe is 13.5 billion years old, so 5 billion years is almost half of the age of the universe.
