The images on this page represent a scale model of the solar system. The sun, the largest object in our solar system, is displayed in the background. Please be patient as the images load, then try clicking o
n each planet's image to learn a bit more! The sizes of the planets, in
proportion to the sun, are as follows:
| Object | Scaled Diameter (inches) | Actual Diameter (miles) |
| Sun | 12 | 865,000 |
| Mercury | .0419 | 3,032 |
| Venus | .1043 | 7,523 |
| Earth | .1098 | 7,928 |
| Mars | .0582 | 4,222 |
| Jupiter | 1.2028 | 88,748 |
| Saturn | 1.0038 | 74,580 |
| Uranus | .4046 | 32,567 |
| Neptune | .3916 | 31,355 |
| Pluto | .029 | 1,554 |

Most solar system models show either the relative sizes of the planets - like the model here - or the relative distances of their orbits. Chances are you've never experienced a true-scale model that shows both. The Museum of Science has built just
such a model in the Boston area called the Community Solar System.
