Largest scale model of the solar system

The largest representation of the Solar System is a 1:20-million-scale “model” that stretches 950 km across Sweden, with planets, minor planets and comets represented by scaled globes or artworks at their relative distances apart. When the Stockholm (now Ericsson) Globe Arena opened in Sweden in February 1989 as the world’s largest hemispherical building, it gave Swedish academics Nils Brenning and Gösta Gahman an idea: if the 110-m-wide building was considered a scaled-down representation of the Sun, how far away would the planets lie, and what size would each one be?
