What is being measured?
Derived by doubling NASA’s approximate 1,740 km radius. This rounded size reference is not a precision lunar shape model.
Use the named object, variant and dimension. A manufactured or natural object can differ from this reference.

Put the length in perspective
One Moon — approximate diameter represents approximately 40,700,000 card lengths measured end to end. This is a length ratio; it does not calculate how the objects pack or fit.
Moon — approximate diameter · 3480000 m
Metre · 1 m · too small to see
Foot (international) · 0.3048 m · too small to see
