What is being measured?
Twice JPL’s 6371.0084 km volumetric mean radius. This equivalent-volume diameter differs from equatorial and polar diameters.
Use the named object, variant and dimension. A manufactured or natural object can differ from this reference.

Put the length in perspective
One Earth — mean diameter represents approximately 149,000,000 card lengths measured end to end. This is a length ratio; it does not calculate how the objects pack or fit.
