World’s largest model of planetary system

The Sweden Solar System is the world’s largest model of our planetary system, built at a scale of 1:20 million and stretching the entire length of the country. The Sun is represented by the Ericsson Globe Arena in Stockholm, the largest spherical building in the world. Sculptures of the planets are placed and sized according to scale, with Mercury, Venus, Earth and Mars in Stockholm, Jupiter at Arlanda Airport, Saturn in Uppsala, Uranus in Gavle, Neptune by the River Söderhamnsån and Pluto in Delsbo, with known asteroids, comets and exoplanets along the way. It all ends with the Termination Shock (the boundary where solar wind transitions to subsonic velocity) at the Swedish Institute of Space Physics in Kiruna.
