0 kgToo small to resolve at this scale; the locator is not the bar width.
Bar length measures mass, not physical size. Both bars start at zero kilograms (kg). Pictures identify the objects only.
A little perspective
1 × 10¹² solar masses is about 6.67 × 10¹⁰ times the mass of Betelgeuse.

1 × 10¹² solar masses
Mass: 1 × 10¹² M☉; definition.
The quantity is exact as entered. Comparisons use the clearly stated specimen, model or nominal measurement.
Betelgeuse
Mass: 15 M☉; rounded model.
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.

How to read the visual
The diagram uses the recorded measurements. Details outside the marked spans do not set the scale.
- The mass of Betelgeuse: This is an illustrative comparison value, not a claim that every example is the same.
Mass is distinct from weight: an object’s mass stays the same as gravity changes.
