There is one in Zurich very similar as well. With the representations of the size of the planets.

Seems there are a whole bunch of them across the planet: https://en.wikipedia.org/wiki/Solar_System_model

Largest one being in Sweden, with a scale of 1:20,000,000 (spanning the whole country): https://en.wikipedia.org/wiki/Solar_System_model

In comparison, both the Zurich and Netherlands one are 1:1,000,000,000

That one in Sweden is huge! Country-wide indeed.
