Scale the Solar System
Build a tabletop or outdoor Solar System scale model. Planet diameters and orbital distances share a scale, which makes the large gaps between planets visible.
Your inputs
Start with the example values, then replace them with your own. For tables, keep the vertical bar separators and use a dot for decimals.
This simplified educational calculation has stated assumptions. Do not use it for navigation, engineering safety or other safety-critical decisions.

How it works
Use mean diameters and orbital semimajor axes, scaled by model Sun diameter / real Sun diameter. Orbits are not shown as current positions.
Worked example
These sample results use the original example inputs in the form. They do not change when you edit your inputs; your own result appears in the workspace.
- Model Sun diameter: 10 cm
| Celestial body | Diameter cm | Orbital distance m |
|---|---|---|
| Mercury | 0.035 | 4.1581 |
| Venus | 0.0869 | 7.7694 |
Read the result carefully
Results depend on the values and assumptions shown above. Change one input at a time to see its effect. A blank or unavailable result means the data does not support a calculation; it is not zero.
