If the sun were 4 pixels wide, how large would a to-scale poster of the solar system be? About 4 feet. This poster provides visual reference to the data in NASA’s planetary fact sheets.
The black dot representing the sun in this graphic is about 1/2mm wide (at 200 DPI, 4 dots). All distances are shown to scale. At this scale, Jupiter would be less than a dot wide and so the planets are not shown to scale. To print each planet at one dot or greater, this poster would have to be about a quarter mile in length. The distance scale has been placed into perspective space in order to fit on a 3 foot wide page.

- Sun: The sun makes up 99.86% of all mass in the solar system.
- Mercury: This planet moves so fast that Einstein’s theory of relativity is required to accurately predict its orbit.
- Venus: Relative to other plants, Venus rotates opposite and is nearly upside down.
- Earth: Axial tilt is the reason for the seasons.
- Mars: No planet has taller mountains or wider canyons.
- Jupiter: The planet of mosts: most mass, most volume, most moons (63). 88 times bigger and it would have been a star. Tatooine, anyone?
- Saturn: The least dense planet in the solar system.
- Uranus: Only one spacecraft has ever visited this planet, which spins on its side.
- Neptune: Like Jupiter, Saturn and Uranus, Neptue has a complex ring system.
