Measurements, assumptions & sources +
Rhine
The Rhine is commonly described as approximately 1,230 km long from its Alpine headwaters to the North Sea. Headwater choice and channel-centreline conventions affect the total.
Encyclopaedia Britannica — Rhine River
The marked approximate main-channel length is calibrated. Unmeasured illustration details are representative.
Charon
Rounded mean-radius model of Charon. The derived area and volume describe a sphere; surface terrain and flattening are omitted.
NASA JPL — Planetary satellite physical parameters
The marked mean diameter is calibrated. Unmeasured illustration details are representative.

Why this measurement?
Why we use 1,230 km
For comparison, this page uses approximate main-channel length. This is labelled approximate; the central value is useful for comparison, while real values or measurement solutions can vary. The recorded range is 1,200 km to 1,250 km.
The Rhine is commonly described as approximately 1,230 km long from its Alpine headwaters to the North Sea. Headwater choice and channel-centreline conventions affect the total.
