How many Earth diameters fit across Jupiter?
Jupiter dominates the Solar System’s planets, but the exact diameter ratio is more useful than a dramatic illustration alone.
Linear ratio10.97×
Using the stated linear measurements, Jupiter is 10.97× Earth.

Jupiter
139,820 kmThe largest planet, with storms and cloud bands wrapped around a rapidly rotating globe.
The answer
A ratio, an analogy and the definitions behind both.
Using the stated linear measurements, Jupiter is 10.97× Earth.
About 10.97× Earth linear spans fit across the selected measurement of Jupiter.
mean diameter versus equatorial diameter
The metre values can be divided as linear spans, but the two entries do not describe identical kinds of boundary.
Earth is measured; jupiter is measured.
Representative, variable and model-dependent values are useful for perspective only when their status remains visible.
