Saturn vs Jupiter
What are they, and what does the difference actually look like?
Two things. One honest scale.

What these two things are
Jupiter
Jupiter is a giant planet composed mainly of hydrogen and helium, orbiting the Sun beyond the asteroid belt.
139,800 kmMean diameterJupiter has about 1.2 times the mean diameter of Saturn.
Both marked spans share one linear scale. Artwork keeps its proportions; poses and surface detail are illustrative.

Saturn
Mean-radius spherical model for Saturn; actual shape is not perfectly spherical. Gravity refers to a conventional atmospheric level, not solid ground.
NASA JPL — planetary physical parameters
The marked mean diameter is calibrated. Unmeasured illustration details are representative.
Jupiter

Why these numbers?
The visual compares mean diameter with mean diameter. The records below preserve each value’s basis and caveats.

- Comparing
- Mean diameter ↔ Mean diameter
- Relative size
- Jupiter is larger on this measurement by a factor of about 1.2. Jupiter's selected measurement is approximately 20.1% greater than Saturn's.
How to read the visual
The labelled spans and stored measurements determine the scale; unmeasured illustration details do not.
- Saturn is labelled approximate; treat the displayed value as a comparison anchor rather than false precision.
- Jupiter is labelled approximate; treat the displayed value as a comparison anchor rather than false precision.
