What this measurement describes
The selected line passes through the object from one side to the other. Where a body is not perfectly spherical, the catalog states which diameter is represented.

Betelgeuse
≈1 billion kmA pulsating red supergiant with a surface so diffuse that its quoted diameter changes with wavelength and time.

The number keeps its meaning.
How certain is the boundary?
The physical boundary or individual size can change. Vastoscope uses a documented reference value to make comparison possible.
What the engine actually divides
Vastoscope compares the SI value in metres for this estimated photospheric diameter. A ratio is mathematically valid as a linear span, while the interface identifies when the two selected definitions differ.

something to stand beside.
These anchors are selected by logarithmic proximity from familiar human, engineered, planetary and cosmic references.

Evidence trail
Where this scale comes from.
Vastoscope keeps the displayed number separate from its measurement type and certainty. Representative and model-dependent values are intentionally labelled instead of presented as exact edges.
