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 50 astronomical units is about 1.66 times the distance of Neptune’s orbital distance.

- Comparing
- Length ↔ Distance
- Relative size
- 50 astronomical units is larger on this measurement by a factor of about 1.66. 50 astronomical units's selected measurement is approximately 66.1% greater than Neptune’s orbital distance's.
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.
