Both marked spans share one linear scale. Artwork keeps its proportions; poses and surface detail are illustrative. A ruler represents the selected distance or unrolled circumference; it is not the physical size of the pictured body.
A little perspective
The length of 30 astronomical units and the distance of Neptune’s orbital distance are approximately the same.

Neptune’s orbital distance
A rounded 30.11 AU semi-major-axis reference, not today’s distance.
Defined examples — our methodology
The marked distance is calibrated. Unmeasured illustration details are representative.

- Comparing
- Length ↔ Distance
- Relative size
- The two selected measurements are approximately equal.
How to read the visual
The labelled spans and stored measurements determine the scale; unmeasured illustration details do not.
- Neptune’s orbital distance is labelled rounded reference; treat the displayed value as a comparison anchor rather than false precision.
