The Sweden Solar System

The Sweden Solar System (SSS) is the world’s largest model of our planetary system. The Sun is represented by the Globe in Stockholm, the largest spherical building in the world, and the planets are lined up in direction north from here.

Distances and sizes are scaled according to 1:20 million, and the inner planets are all in the Stockholm area. The outer planets follow in the same direction with for instance Neptune in Söderhamn and the dwarf planet Pluto in Delsbo, 300 km from the Globe. A number of minor planets and comets also populate SSS, which now extends from the very south to the very north of Sweden. There is a host institution for each model. SSS is a pedagogical instrument and conveys a direct feeling of the enormous distances in space, and how small the planets are compared to the Sun. Art, mythology and science merge in this project, and SSS connects many different places and different type of activities around Sweden.

NEWS: A new model of the planet Venus was inaugurated outside the House of Science (Vetenskapens Hus) on May 9, 2016.

The Globe Arena in Stockholm is the largest spherical building in the world, and it represents the Sun in the SSS. This picture shows the Globe lit by an animation, which included a sequence showing flares on the solar surface, during the inauguration of the International Year of Astronomy 2009.

The model of Mercury is heated to symbolize its closeness to the Sun. Craters are depicted, and on the support structure various symbols are seen, like for the orbital drift in accordance with Einstein’s theory of relativity. The museum is now under reconstruction, and the model is stored at the moment until a new temporary place has been found.

A new model of Venus was inaugurated on May 9, 2016 in the park outside the House of Science (Vetenskapens Hus), AlbaNova University Centre, Stockholm. The model is sculpted by Peter Varhelyi, and on five plates surrounding the model are schematic descriptions of: Venus in the sky as morningstar, Venus in its orbit, Venus’ phases, the greenhouse effect on Venus, and names of the goddess of love from different cultures.

The Observatory museum in Stockholm is closed, and its Venus model has been moved to the upper floor in Vetenskapens Hus.

The plans to create a nice model of Saturn are advancing. In 2010 an artistic model of the moon Titan was inaugurated in central Uppsala at the Celsius House, where the 18th century astronomer Anders Celsius worked. In addition, several Saturn moons have been given form by pupils in school classes in the area.

A symbolic and playful outdoor model of Uranus was inaugurated in Oct 2012 (see picture) in Lövstabruk south of Gävle. The model was built in steel by Forsmark Mechanical Workshop at the Forsmark nuclear plant located close to Lövstabruk, and where the element Uranium plays an important role. The unusual tilt of Uranus’ axis is marked.

Neptune, symbolizing the god of the water and the sea, is located in the central park of Söderhamn, a coast town with long traditions of fishing and sailing. The model is lit from inside by blue light in the night.

Pluto and Charon are supported by two tomb-like pillars reminding of the mythological meaning of Pluto (Hades), the god of the underworld. One can also be reminded of the meteorite impact that took place here 90 million years ago, when all life became extinct over a large area, and from which the Dellen lake system formed.

Pluto is not classified as a planet anymore. It is a dwarf planet.

The model of the dwarf planet Sedna, created by Arto Koskitalo, was inaugurated in 2005 at the science centre ”Teknikens Hus” located in Luleå in northern Sweden, not far from the arctic cirle. In arctic mythology, Sedna represented the ”goddess of the frozen sees” from where she supplied the eskimos with seals and whales. Sedna is comparable to Pluto in size, and belongs to a distant swarm of minor planets called the Kuiper Belt
