Both marked spans share one linear scale. Artwork keeps its proportions; poses and surface detail are illustrative.
A little perspective
The length of 10,000,000 light-years and the diameter of Local Group are approximately the same.

10,000,000 light-years
The quantity is exact as entered. Comparisons use the clearly stated specimen, model or nominal measurement.
Local Group
A rounded 10 million light-year span for the neighbourhood of galaxies. Galaxy groups have no solid edge.
Defined examples — our methodology
The marked diameter is calibrated. Unmeasured illustration details are representative.
Measurement details
Why these numbers?
The visual compares length with diameter. The records below preserve each value’s basis and caveats.
Local Group
3.066 MpcDiameter · rounded reference
A rounded 10 million light-year span for the neighbourhood of galaxies. Galaxy groups have no solid edge.
- Comparing
- Length ↔ Diameter
- Relative size
- The two selected measurements are approximately equal.
How to read the visual
The labelled spans and stored measurements determine the scale; unmeasured illustration details do not.
- Local Group is labelled rounded reference; treat the displayed value as a comparison anchor rather than false precision.
