In Florianópolis, Brazil, there's a thing called Projeto Helius where someone has placed plaques along the waterfront showing the locations of the planets, to scale. They start off deceptively close together for the inner planets, just a few minutes' walk apart, but then it really takes a while to reach the outer planets.

I walked as far as Neptune but, like the author of the above blog post, didn't continue on to Pluto. (It isn't depicted on the map, but I just checked and all of these markers are Ingress portals/Pokestops, so it's easy to find other people's maps that show them. Pluto is a little south of the end of the park there.)

- anonymousiam 10y agoPluto's orbit is so eccentric that perigee (the point closest to the sun) is actually inside the orbit of Neptune.
- anonymousiam 10y agoAnd of course I stupidly used the wrong term for perihelion. Perigee refers to the closest point to EARTH not the SUN.
- kbutler 10y agoBut at this distance, it is the same... -- Robert Heinlein A little less the same than Heinlein's original context, though Pluto was involved there, too. Anybody catch the reference?
- metaobject 10y agoYour statement may still be correct, though.
- isostatic 10y agoJust stick with periapsis and thank Kerbel for making it easier to understand basic principles of orbits.
- david-given 10y agoThere's one in Zürich, too; the Planetenweg: https://de.wikipedia.org/wiki/Planetenweg_Uetliberg https://de.wikipedia.org/wiki/Planetenweg_Uetliberg It's the same scale, 1:10^9, and is about seven and a half kilometres long. Each station has a model of the planet, to scale. The sun is a big yellow ball on a post. The gas giants are small balls. The rocky planets are little flecks of material encased in plastic... There are two Plutos, marking the summer and winter extremes.
