Very cool!

That is cool.
More on Solar System models.
I was going to mention the South Station Jupiter pictured in you link. I’ve seen it many times. I’ve also seen Earth and I think Venus. I’ve never seen Pluto, as that’s a long way away.
When I was in high school we did the model based on a 100 yard sports field. It was a lesson I never forgot. No textbook could convey it like sitting in the stands looking down at the scale model could. That experiment should be mandatory. We had to do the math ourselves, but for younger kids you could just make them measure themselves.
There is a really awesome solar system model in Eugene, Oregon. It has Pluto at 3.7 miles away from the sun. The projec t is described here:

I take this walk (or something very like it) with my kids and usually a couple of their friends every year. It’s good fun.
“curator of the solar system.”
I’d love that job. 
I wonder if there’s any one of these relatively nearby (I live the Netherlands). I’d love to see one.
There’s one here in Sweden (literally cross-country; the Sun is in Stockholm and the marker for the Terminal Shock is up above the Arctic Circle) and there’s one in the Hague.
I wish I’d known about the Sweden Solar System earlier! I’ve been near Mercury and Venus without realizing it.
There was an outfit that was selling bronze plaques of the planets to use on a trail scale model of the solar system. They were meant to be mounted on a post. The Sun was not supplied but was scaled at three feet in diameter, the size of those spheres you see on high tension lines to warn aircraft. Pluto (it was still a planet then) would be several kilometers away.
