I learned recently from a Lemmy comment that it's easier to launch something out of the solar system than into the sun. I guess it makes sense, because escape velocity from Earth is only about 16km/s, while the Earth is moving around 30km/s relative to the sun, and you'd have to slow a thing down closer to 0km/s to deorbit it.

I think sometimes it's worth it to make the extra effort, though, in order to send the right message.
