Juno spacecraft
NASA’s Juno spacecraft spans approximately 20 m across its three deployed solar arrays and had a launch mass of about 3,625 kg. The span excludes the magnetometer boom beyond one array.
The marked deployed solar-array span is calibrated. Unmeasured illustration details are representative.

Why this measurement?
Why we use 20 m
For comparison, this page uses deployed solar-array span. This is labelled approximate; the central value is useful for comparison, while real values or measurement solutions can vary. The recorded range is 19 m to 21 m.
