There's an episode on "Space & Beyond" where they show all the planets in scale to the realworld on an actual football field.
Then to show Planet 9 distance they have to get in a car and drive a few miles.
That worked for me.

It communicates the scales really well, while only taking up a little over a foot of bookshelf space when not being "navigated". I have two heavy metallic retro looking rocket bookends for it.
