Astronomers know full well that the sun is very slowly getting brighter, and in a billion or so years time it will make Earth too hot to live on.
One scientist is now proposing a radical solution that will let humans live on this planet for longer – physically moving it away from the sun.
Albert Zijlstra, a professor of astrophysics at the University of Manchester, suggests shifting Earth further back from the sun by about three million miles.
At the moment, Earth is orbiting the sun at a distance of 93 million miles (150 million km) but this needs to extended to at least 96 million miles (155 million km), he says.
This movement would extend a year to 380 days, meaning we'd have to insert an extra 15 days into a calendar year somewhere.
'Earth will get warmer, and warmer – best estimates are that in one or two billion years, the oceans will begin to boil away,' Professor Zijlstra told MailOnline.
How would it work?
When a planet (such as Earth) slows down in its orbit, it moves closer to the sun. Likewise, when a planet speeds up in its orbit, it moves away from the sun.
Therefore, if we want to move Earth away from the sun, the objective is to speed up Earth.
Professor Zijlstra proposes doing this using a gravity assist or 'slingshot' manoeuvre, which are already used to speed up spacecraft after they've been launched from Earth.
It's a little-known fact that gravitational slingshots can also be used to reduce the speed of a spacecraft, which have the opposite effect on the planet - speeding it up.
Rather than a spacecraft - which would be too small - he proposes using a massive asteroid the size of a city.

Killing cows to meet their CO2 quota is just one step towards killing a million humans to meet their CO2 quota
Yeah, but now they need the cows in order to boost Earth to a higher orbit.
It'll be here before you know it.
Yep. There are a lot of them.
The one I referenced was based on a 1933 science fiction novel.
How about we move just the Scientist three million miles farther from the sun?
The calendar would be the least of our problems.
True, in a billion years we may see the RAPTURE before then. Those left behind will go to the place they deserve.
If I were a betting man, I’d bet that some natural or human catastrophe will cause the earth to be uninhabited a billion years from now anyway , except for maybe the cockroaches, and they’re on their own.
You forgot Keith Richards.
First we’re going to control the climate now we’re going to drive the Earth around the universe looking for a cool place to park. Reminds me of “Childhood’s End”.
It’s “tha” science. Embrace it.
What would we do about the moon?
Another wacko idea to “save the earth!”
Remember the 1970s when they wanted to stop “THE COMING ICE AGE” by mining coal, grind it to dust, mix it with oil and spray it on the glaciers and ice caps to increase warming?
I propose that we send spacecraft with giant fire extinguishers to the sun.
LOL!
The same people who can’t stop extended car warranty calls want to move a planet.
What they are admitting is that the cause of GW is the sun
That would go a long way to making the world a safer place. Rounding up the megalomaniacs would be a great help too. It seems that every problem we have today is caused by these megalomaniacs nudging the world to make to their desire.
When the famines hit, few will connect the dots to see it came from global warming solutions.

If things in lower orbits move faster, why does speeding up allow them to leave the orbit entirely?

Kepler’s First Law describes the shape of an orbit.

The orbit of a planet around the Sun (or a satellite around a planet) is not a perfect circle. It is an ellipse—a |flattened| circle. The Sun (or the center of the planet) occupies one focus of the ellipse. A focus is one of the two internal points that help determine the shape of an ellipse. The distance from one focus to any point on the ellipse and then back to the second focus is always the same.
