The marked time is calibrated. Unmeasured illustration details are representative.
Earth–Sun distance
One astronomical unit is exactly 149,597,870,700 m. It is a useful Earth–Sun orbital scale, not the separation at every instant. Light takes about 8 minutes 19 seconds to cross it.

Why this measurement?
Why we use 3.5 min
For comparison, this page uses time. This is labelled reference interval: an explicit comparison model rather than a claim that every example has the same value.
