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 diameter of Betelgeuse is about 1.3 times the length of 5 astronomical units.

5 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.

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
- Betelgeuse is larger on this measurement by a factor of about 1.3. Betelgeuse's selected measurement is approximately 30.2% greater than 5 astronomical units'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.
