用英语表述一个你想象得到的将地球搬离太阳系的方法

When people learn that energy output from the Sun is increasing, and will boil away the planet’s oceans within a billion years, they wonder if there’s any way to stop the process. Obviously, we can’t stop the Sun from shining and increasing its energy output. But is there a way humans could move the Earth further away from the Sun?

The answer is yes. Well, it’s theoretically possible. Not with today’s technology, and not without an enormous amount of energy, but the laws of physics say it’s possible. In fact, nature does it all the time.

The trick is to replicate a natural process called a 3-body interaction. This is what happens when you have nice orbit perturbed by a 3rd object. In this case, we’ve got the Earth nicely orbiting the Sun. But if we could have an asteroid pass by the Earth in just the right way, its gravity would pull our planet out of its orbit just a tiny bit.

Instead of its current elliptical orbit, the Earth would start to spiral
