The Sweden Solar System

The Sweden Solar System is the world's largest permanent scale model of the Solar System. The Sun is represented by the Ericsson Globe in Stockholm, the largest hemispherical building in the world. The inner planets can also be found in Stockholm but the outer planets are situated northward in other cities along the Baltic Sea. The system was started by Nils Brenning and Gösta Gahm^[1] and is on the scale of 1:20 million.^[2]

The system

The bodies represented in this model include the Sun, the planets (and some of their satellites), dwarf planets and many types of small bodies (comets, asteroids, trans-Neptunians, etc.), as well as some abstract concepts (like the Termination Shock zone). Because of the existence of many small bodies in the real Solar System, the model can always be further increased.

The Sun is represented by the Ericsson Globe (Globen), Stockholm, which is the largest hemispherical building in the world, 110 m in diameter. To respect the scale, the globe represents the Sun including its corona.

Inner planets

Mercury (25 cm in diameter) is placed at Stockholm City Museum, 2,900 m from the Globe. The small metallic sphere was built by the artist Peter Varhelyi.
Venus (62 cm in diameter) is placed at KTH (Royal Institute of Technology), 5,500 m from the Globe. The model, made by the United States artist Daniel Oberti, was inaugurated June 8, 2004, during a Venus transit. The model fell and shattered around June 11, 2011. Due to construction work at the location of the model of Venus it has been removed and as of October 2012 cannot be seen. There is another model of Venus located at the Observatory Museum.
Earth (65 cm in diameter) is located at the Swedish Museum of Natural History (Cosmonova), 7,600 m from the Globe. Satellite images of the Earth are exhibited beside the Globe. An elaborate model of the Moon (18 cm in diameter) is on display in another part of the museum.
Mars (35 cm in diameter) is located at Mörby Centrum, a shopping centre in Danderyd, a suburb of Stockholm. It is 11.6 km from the Globe. The model, made in copper by the Finnish artist Heikki Haapanen, is connected by an "umbilical cord" to a steel plate on the floor having an Earth image.^[3] The globe also features marks that represent some typical Martian chemical elements.

Outer planets

Jupiter (7.3 m in diameter) is placed at the roundabout near Sky City, in Stockholm Arlanda Airport in Sigtuna Municipality, 40 km from the Globe. It is made as a flower decoration, with different flowers representing different zones of the giant gas planet. There are plans to build a 3D model.
Saturn (6.1 m in diameter) is placed outside the old observatory of Anders Celsius, in the so-called Celsius Square, at centre of Uppsala, 73 km from the Globe. Inaugurated during the International Year of Astronomy,^[4] the model is a mat with a picture of Saturn, but will eventually grow to crown a school planetarium at the city. In addition, several schools in Uppsala are to provide moons of Saturn: the first completed was Enceladus (diameter 2.5 cm) at Kvarngärdesskolan.^[5]
Uranus (2.6 m in diameter) was vandalized and the new model is planned for somewhere in Gävle, 143 km from the Globe.
Neptune (2.5 m in diameter) is located by the river Söderhamnsån in Söderhamn, a coast town with tradition of fishing and sailing (which relates to Neptune as the deity of the seas). Placed 229 km from the Globe, the model is made of acrylic and, at night, shines with a blue light.

Dwarf planets

Pluto (12 cm in diameter) and its moon Charon are placed near the southern of the Dellen lakes, in Delsbo, 300 km from the Globe. The lakes are thought to be formed by a meteorite impact 90 million years ago. The two bodies' sculptures are supported by two gravelike pillars (as Pluto is the deity for death), made up with dellenite, a rare mineral formed at that place by the meteorite impact.
Ixion (6.5 cm in diameter), a dwarf planet candidate, is located at Technichus, a science center in Härnösand, 360 km from the Globe. The sculpture is an orb held by a hand with the arm. This plutino was discovered by a team which included scientists from Uppsala.
Eris (13 cm in diameter) is located at Umestans Företagspark, Umeå, 510 km from the Globe. Made by Theresa Berg, the golden model tells the mythical story about how the goddess started a quarrel between other Greek deities, starting with an apple bearing the inscription καλλίστῃ ("to the most beautiful one").
Sedna (10 cm in diameter), another dwarf planet candidate, is located at Teknikens Hus, a science center in Luleå, 912 km from the Globe.

Other bodies

the near-Earth Object Eros is located at Mörbyskolan, a school in Danderyd Municipality (where Mars is located), 11 km from the Globe. It was created as a Valentine's Day project in gold, modeled after Eros, the god of love. The dimensions are 2 × 0.7 × 0.7 mm (0.98 mm³).
the asteroid Saltis is located at Saltsjöbaden's Kunskapsskola, a school near the Stockholm Observatory. The asteroid was discovered by A. Brandeker in 2000, using a telescope at the observatory, and the body was named after the observatory's location, Saltsjöbaden.
the asteroid Palomar-Leiden (0.2 mm in diameter) is located in a park in Alsike, Knivsta Municipality, 60 km from the Globe. It's not a sculpture but a dot on a map of the System, placed in front of Erik Ståhl's monumental cosmic sculptures.
Halley's Comet is located at Balthazar Science Center, in Skövde. Inaugurated on December 16, 2009, there are actually four models of the comet: three placed outdoors, based on schoolchildren's drawings, plus one indoors, consisting of a laser passing through a block of glass.
Comet Swift-Tuttle is placed at Kreativum, a science center in Karlshamn. The comet's orbit is closest to the Globe in inner Stockholm and farthest in Karlshamn, 390 km away.
The Termination Shock is at the edge of the heliosphere, it is the boundary where the solar wind transitions to subsonic velocity. No sculpture currently represents the termination shock, but a foundation for a future sculpture exists at the Institute of Space Physics, 950 km from the Globe, in Kiruna, above the Arctic Circle.
