What this measurement describes
Distance measures separation between positions. Comparisons count linear spans; they do not turn the gap into a physical object.

The number keeps its meaning.
How certain is the boundary?
This is an observed measurement. The displayed precision follows the cited reference and should not be read as infinite accuracy.
What the engine actually divides
Vastoscope compares the SI value in metres for this Sun-to-star distance. A ratio is mathematically valid as a linear span, while the interface identifies when the two selected definitions differ.
Familiar scale bridges

something to stand beside.
These anchors are selected by logarithmic proximity from familiar human, engineered, planetary and cosmic references.
Galactic · GalaxiesProxima distance ↔ Milky Way23,593×Our barred spiral galaxy, containing the Sun and hundreds of billions of stars.
Stellar · StarsProxima distance ↔ Sun28.79 million ×The star containing almost all the solar system’s mass and powering nearly every surface ecosystem.
Planetary · Solar systemProxima distance ↔ Earth3.15 billion ×Our ocean world, measured by mean diameter — the anchor for familiar planetary comparisons.
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.
