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 4.25 light-years and the distance of Distance to Proxima Centauri are approximately the same.

- 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.
- Distance to Proxima Centauri is labelled approximate; treat the displayed value as a comparison anchor rather than false precision.
