Jupiter diameter and size comparison
Jupiter uses a mean diameter of 139,822 kilometers. Its familiar bands appear on an idealized sphere here so that one consistent diameter can be compared across the collection.

A little more perspective
JPL’s 71,492-kilometer equatorial radius is larger than its 69,911-kilometer mean radius. The scene deliberately uses the mean field; it does not preserve Jupiter’s actual equatorial bulge or claim a solid ground surface at the visible clouds.
The displayed diameter is 2 × 69,911 km = 139,822 km. Doubling the source radius uncertainty gives ±12 km for diameter. The source defines mean radius through an equivalent-volume sphere. Its review date is not a new measurement date.

For a presentation or a research note, include the subject, the measurement definition, and the measurement used. A picture alone cannot explain those choices. The comparison guide explains how to export an image and its source notes together.
