Sources & method
Circles compare equatorial diameters from the NASA Planetary Fact Sheet. Distances, rings, surface details and volumes are not represented. Values are rounded reference measurements.
Ratio = first value ÷ second value. For areas, side lengths use the square root of the area ratio. Diameter and height use a linear scale.
