Charon1,212 kmMean diameter · approximate
Both marked spans share one linear scale. Artwork keeps its proportions; poses and surface detail are illustrative.
A little perspective
The mean diameter of Charon is about 1.21 times the length of 1,000 kilometres.

- Comparing
- Length ↔ Mean diameter
- Relative size
- Charon is larger on this measurement by a factor of about 1.21. Charon's selected measurement is approximately 21.2% greater than 1,000 kilometres's.
How to read the visual
The labelled spans and stored measurements determine the scale; unmeasured illustration details do not.
- Charon is labelled approximate; treat the displayed value as a comparison anchor rather than false precision.
