Jupiter and Earth: comparing diameters

Both dimensions are volume-equivalent diameters. The outer atmospheres and satellite systems are not part of the measurement.

Jupiter: a dimension about 10.97 times that of Earth using the adopted values.

Dimensions adopted for the calculation
ReferenceDimension
Jupiter139,820 km
Mean diameter ≈ 139 800 km
Earth12,742 km
Mean diameter ≈ 12 740 km

Calculation: 139,820 km ÷ 12,742 km, after conversion into the same unit. The ratio calculated from the catalogue data is about 10.97.

Both illustrations use a common factor for the stated dimension. Positions aid reading and do not represent physical separation.

Check the conventions

Jupiter

Mean diameter calculated from the volume-equivalent radius in the NASA/JPL table. Rings and the outer atmosphere are excluded.

Approximate catalogue reference; a source is provided, but the measurement has not been individually audited.

Earth

Mean diameter calculated from the volume-equivalent radius in the NASA/JPL table. Rings and the outer atmosphere are excluded.

Approximate catalogue reference; a source is provided, but the measurement has not been individually audited.

Choose another reference

Replace an object in the explorer, keep the common scale factor and try predicting the new ratio before reading it.
