A little perspective
Put two worlds beside each other. Discover how big they really are—and how small the familiar can become.
Body diameters to scale. Positions and surface artwork are illustrative; Saturn’s rings are excluded.
A change of perspective
10.973× the diameter. See how the two worlds measure up.
Diameter is a distance across an object. Volume grows with the cube of that distance.
Choose a size to bring this comparison down to Earth.
Earth: Twice the source mean radius; body diameter only, excluding rings.
Jupiter: Twice the source mean radius; body diameter only, excluding rings.
How we measure size →Choose two objects, compare their true diameters, or shrink them to a scale you can hold in your hand. There is no finish line. Just another way to see our place in things.
