The mean diameter of Jupiter is about 1.2 times the mean diameter of Saturn. Selected basis: approximate values.
Both rulers start at the same zero and share one linear scale. Artwork keeps its original proportions.
116,500 km - Mean diameter; approximate.
Saturn is a giant planet made mostly of hydrogen and helium, distinguished by its extensive ring system.
Mean-radius spherical model for Saturn; actual shape is not perfectly spherical. Gravity refers to a conventional atmospheric level, not solid ground.
