Congo River
The Congo River is a major waterway in Central Africa, flowing through dense rainforest and forming an extensive drainage basin.
Also known as: Zaire River, Congo
How big is it?
4,700 km long

Approximate river-system length · approximate
Typical recorded range: 4,600 km to 4,800 km.
A little perspective
About the same scale as Callisto.
Callisto: Callisto is a natural satellite of Jupiter, with a heavily cratered icy surface.

Congo River
The Congo river system is approximately 4,700 km long when the Chambeshi is treated as its remotest source. Choosing the Lualaba by discharge or another centreline convention changes the total.
Encyclopaedia Britannica — Congo River
The marked approximate river-system length is calibrated. Unmeasured illustration details are representative.
Callisto
Rounded mean-radius model of Callisto. 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 4,700 km
For comparison, this page uses approximate river-system length. This is labelled approximate; the central value is useful for comparison, while real values or measurement solutions can vary. The recorded range is 4,600 km to 4,800 km.
The Congo river system is approximately 4,700 km long when the Chambeshi is treated as its remotest source. Choosing the Lualaba by discharge or another centreline convention changes the total.
