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

Question

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?

Answer 1

Earth orbits the Sun at more than 100000 km/h. That velocity (or at least a big part of it) needs to be gone in order for an object to “fall” into the Sun. This assumes the object has already left Earth and Earth’s orbit, which also requires changes in velocity.
