Why is the earth supposed to move thus far?
Warning, spoilers ahead.
In the film The Wandering Earth, the earth is supposed to move to another solar system, because the sun is getting stronger and larger over a short period of time.
However, why is the earth not only moved a little more out to the outer planets, instead of actually tried to "wander" to another system?
Is there an in-universe explanation I missed?
Best Answer
This is explained in the first five minutes of the movie: in less than 100 years the Sun will engulf Earth, and in 300 years our solar system will no longer exist. Considering that we need a sun for warmth etc., Earth needs to be moved to another sun, i.e. out of our current solar system.
The Sun is rapidly degenerating and expanding. At this rate, the Sun will engulf Earth in 100 years. Within 300 years, the Solar System will no longer exist.

Why does the Earth have to move?
[+] Much like all the planets in our Solar System, Earth orbits the Sun at a much speedier clip than its rotational speed. In order to keep us in our stable orbit where we are, we need to move at right around 30 km/s.Why is the Earth moving away from the Earth?
The sun's weaker gravity as it loses mass causes the Earth to slowly move away from it. The movement away from the sun is microscopic (about 15 cm each year).Is Earth really moving?
The earth rotates once every 23 hours, 56 minutes and 4.09053 seconds, called the sidereal period, and its circumference is roughly 40,075 kilometers. Thus, the surface of the earth at the equator moves at a speed of 460 meters per second--or roughly 1,000 miles per hour.Why do we not feel the Earth move in when we are moving?
We do not feel any of this motion because these speeds are constant. The spinning and orbital speeds of Earth stay the same so we do not feel any acceleration or deceleration. You can only feel motion if your speed changes.Why Can't We Feel The Earth Spinning (Explained)
