Nothing in the Universe is static. In the milky way, billions of stars orbit the galactic center.
Some, like our sun, are pretty consistent, keeping a distance of around 30,000 light years from the galactic center, completing an orbit every 230 million years.

This dance is not an orderly ballet - more like a skating rink filled with drunk toddlers. This chaos makes the galaxy dangerous. Our solar neighbourhood is constantly changing, with stars moving hundreds of kilometers every second.

Only the vast distances between objects protect us from the dangers out there. But we might get unlucky in the future. At some point we could encounter a star going supernova. Or a massive object passing by and showering earth with asteroids.

If something like this were to happen we would likely know thousands, if not millions of years in advance. But we still couldn’t do much about it.

Unless… we move our whole solar system out of the way.

    Imagine leaving our Sun and entire Solar system one day (close to its death) for another. Being sad for leaving humanity's home behind and excitement for a new world ahead. What a mixed feeling could it be. Don't know if I am glad or not I'm not going to experience it.

    When we power the thruster to move the Sun imagine Mars being right in the Sun's direction of travel. This will bring Mars closer to the Sun (the Sun doesn't repel planets, their speed and distance gives them an orbit that keeps them away) thus Mars orbit will now be an ellipse instead of a circle and by the time it goes half a turn (behind the Sun's direction of travel the gravity pull will be less and Mars will just arc away, Long story short every planet will either crash into the sun or get left behind (rogue planets drifting)

    So then, does this mean that no passing star could ever eject the earth out of the inner solar system? We could just move the sun out of the way which would then pull the earth and everything else in the solar system along with it...
