Want to take a road trip through our solar system? Warm up your Volvo and point yourself toward Stockholm, where a 950-km scale model of the solar system begins. You can tour Sweden while getting a sense of our solar neighborhood's scale.
The Sweden Solar System runs from Stockholm to Kiruna up in the northern part of Sweden, a trip that Google Maps estimates takes 15 hours, even if you aren't stopping to gawk at all the models of celestial bodies along the way. At a 1:20 million scale, it's the largest scale model of the solar system, and it all starts at the Ericsson Globe Arena in Stockholm, which is the world's largest spherical building. The rest of the solar system is represented by sculptures, with Mercury, Venus, Earth, and Mars all sitting in the Stockholm area, Jupiter in Sky City, and Pluto way up in Delsbo, with known asteroids, comets, and exoplanets along the way. It all ends with the termination shock, which sits, appropriately, at the Swedish Institute of Space Physics in Kiruna, where you can not only say you've mapped the fake solar system with your car, but also visit the observatory and lay your eyes on the real thing.
At the moment, however, the solar system is incomplete. The model Uranus, which was located in Gävle, was vandalized and had to be removed. I was not able to find any photos of the graffiti, but I fear it was punny.
