What this measurement describes
The selected measurement follows the object’s longest or specifically defined linear direction.

Halley’s Comet nucleus
≈11 kmThe dark icy nucleus behind Halley’s spectacular coma is roughly city-sized.
WonderMost of the visible comet is gas and dust spread far beyond this solid core.

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 representative nucleus length. 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.
