A little perspective
Volga vs Moon: length comparison
The main-channel length of the Volga is about 1.02 times the mean diameter of the Moon.
The Volga is a river in central Russia, running from the Valdai Hills to the Caspian Sea.
The Moon is Earth’s natural satellite and the brightest large object in Earth’s night sky.
Both rulers start at the same zero and share one linear scale. Artwork keeps its original proportions.
Measurements, assumptions & sources +
Volga
Approximate main-channel length: 3,530 km; approximate; range 3,500 km–3,550 km.
The Volga is commonly described as approximately 3,530 km long from the Valdai Hills to the Caspian Sea. Reservoir routing and channel-centreline conventions affect the total.
Encyclopaedia Britannica — Volga River
The marked approximate main-channel length is calibrated. Unmeasured illustration details are representative.
Moon
Mean diameter: 3,475 km; approximate.

Why this measurement?
Why we use 3,530 km
We compare the main-channel length of the Volga. This is an estimate; check the notes for its rounding and uncertainty. The recorded range is 3,500 km to 3,550 km.
The Volga is commonly described as approximately 3,530 km long from the Valdai Hills to the Caspian Sea. Reservoir routing and channel-centreline conventions affect the total.
