Betelgeuse6.511 AUDiameter · rounded model
Both marked spans share one linear scale. Artwork keeps its proportions; poses and surface detail are illustrative.
A little perspective
The length of 10 astronomical units is about 1.54 times the diameter of Betelgeuse.

10 astronomical units
The quantity is exact as entered. Comparisons use the clearly stated specimen, model or nominal measurement.
Betelgeuse
A deliberately rounded red-supergiant model. Its apparent edge varies with wavelength and the star changes over time.
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.
Betelgeuse
6.511 AUDiameter · rounded model
A deliberately rounded red-supergiant model. Its apparent edge varies with wavelength and the star changes over time.
- Comparing
- Length ↔ Diameter
- Relative size
- 10 astronomical units is larger on this measurement by a factor of about 1.54. 10 astronomical units's selected measurement is approximately 53.6% greater than Betelgeuse's.
How to read the visual
The labelled spans and stored measurements determine the scale; unmeasured illustration details do not.
- Betelgeuse is labelled rounded model; treat the displayed value as a comparison anchor rather than false precision.
