That's what I meant with eccentric path though: As far as I know Pluto is not always that far out, there are points in time where it's closer to the sun than Neptune - which should be a good moment when either Uranus or Neptune could be used to aerobreak.

Edit: but only when they also line up correctly, which is why I think it would take hundreds of years of waiting.

Edit2: After watching the linked video, Uranus would be out, since Pluto is never close to it, but Neptune might work at some point in time when these planets are close.

The Neptune-Pluto alignment is one that might be interesting to explore on a solar system simulator. I suspect you might have to wait a fair fraction of a thousand years for that though, at a minimum.

I actually tried to find a good simulator for that reason, but all the web simulators I've found didn't have a reasonable time slider UI.

There's a KDE astronomy simulator I've used that seems pretty good, though I haven't played with it for a while. Celestia IIRC: http://www.cyberciti.biz/tips/celestia-astronomy-linux-progr...
