Why does it take more Delta-V to shoot somebody into the Sun?

1.25K views

I saw a meme that stated that, if you’re mad at someone, it take less Delta-V to launch them out of the solar system than in does to fire them into the Sun.

Why is that? Wouldn’t the attraction of the Sun’s mass be greater and provide assistance?

Oh, I just thought of one other thing. The meme you’re talking about, forgot to account for something: gravity assists.

Sometimes called a “slingshot maneuver,” it’s possible to cheat at this ‘delta-v’ game by taking advantage of moons and other planets, and flying past them at just the right speed and distance so that their gravity will bend your path in the desired direction.
