Jupiter at South Station, part of Museum of Science, Boston scale model. This was also used in FETCH! with Ruff Ruffman

Solar system models, especially mechanical models, called orreries, that illustrate the relative positions and motions of the planets and moons in the solar system have been built for centuries. While they often showed relative sizes, these models were usually not built to scale. The enormous ratio of interplanetary distances to planetary diameters makes constructing a scale model of the solar system a challenging task. As one example of the difficulty, the distance between the Earth and the Sun is almost 12,000 times the diameter of the Earth.

If the smaller planets are to be easily visible to the naked eye, large outdoor spaces are generally necessary, as is some means for highlighting objects that might otherwise not be noticed from a distance. The objects in such models do not move. Traditional orreries often did move and some used clockworks to make the relative speeds of objects accurate. These can be thought of as being scaled in time instead of distance.


One scale model, designed to be easily replicated, is called The Thousand-Yard Model [1] and spans about a kilometre. In it, the Earth is represented by a peppercorn. A school class building this model might tape the peppercorn to an index card to make it more visible. Another scale model is the 1:10 000 000 000 model, in which 100,000 km is represented by 1 cm. In this model, the Sun is 600m from the Kuiper belt and dwarf planet Pluto. The largest scale model in the world is the Sweden Solar System. Binomial name Piper nigrum L.

A model based on a classroom globe

A classroom globe

Relating the size of the Solar system to familiar objects can make it easier for students to grasp the relative distances. Most classroom globes are 41 cm (16 inches) in diameter. If the Earth were reduced to this size, the Moon would be a 10 cm (4 in) baseball floating 12 metres (40 feet) away. The Sun would be a beach ball 14 stories tall (somewhat smaller than the Spaceship Earth ride at Epcot) floating 5 kilometres (3 miles) away. While a complete model to this scale has never been built, here is what a solar system built to that scale would look like. The scale is approximately 1:31,000,000.

If the scale of the above model is increased to 1:310,000,000, i.e. all distances and sizes reduced by a factor of 10, then the Earth and Venus can be modeled by ping pong balls, the Moon and smaller planets by various size marbles or lumps of modeling clay, the gas giants by balloons or larger playing balls, and a circle the diameter of the Sun can be drawn on the floor of most classrooms. The scale distance to α Centauri would be 1/3 of the way to the Moon.

A model based on a sports field

Relating the size of the Solar System to familiar objects can make it easier for students to grasp the relative distances. Most American schools have a football field associated with the high school (100 yards or 92 meters long). Other schools may have a soccer field nearby (90 to 120 m long). If the Sun was reduced to slightly less than one inch (21 mm), Pluto would be a 0.002 inch (0.05 mm) speck floating 100 yards (91.4 meters) away. Jupiter would be less than three-thirty-secondths of an inch (2.38 mm) in diameter and would sit on the 13 yard (11.88 m) line. Uranus would be less than one-thirty-secondth of an inch (0.79 mm) sitting nearly on the 50 yard (45.72 m) line. At that scale, the speed of light would be about 1 inch every 5 seconds (5 mm per second). Light takes about 5.5 hours to go from the Sun to Pluto. Here is what the Solar System built to that scale would look like. This complete model would be simple to make with scale planets taped to wood stakes or metal rods. The scale is approximately 1:64,700,000,000. United States simply as football, is a competitive team sport that is both fast-paced and strategic. ...

Misleading models

Major features of the solar system, distances of centers of the planets to a scale. Terrestrial planets are 10 times enlarged.
Major features of the solar system, distances of centers of the planets to a scale. Terrestrial planets are 10 times enlarged.

The models sketched here are an eye opener to many people interested in, but not knowing much about astronomy. They are far cry from the drawings of the solar system one usually sees in books or in the net, such as the one to the right. Even if it is stated in the text that the layout is not to scale, it is often difficult for the reader to fully comprehend how discrepant the scale of the distances in the image is compared to the sizes of the objects depicted.
