1,000,000 solar masses
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 mass is calibrated. Unmeasured illustration details are representative.
Measurement details
Why these numbers?
The visual compares mass with mass. The records below preserve each value’s basis and caveats.
Betelgeuse
15 M☉Mass · rounded model
A deliberately rounded red-supergiant model. Its apparent edge varies with wavelength and the star changes over time.
- Comparing
- Mass ↔ Mass
- Relative size
- 1,000,000 solar masses is larger on this measurement by a factor of about 66,700.
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.
