Bar length measures mass, not physical size.
A little perspective
1 solar mass and Sun have approximately the same mass.

1 solar mass
The quantity is exact as entered. Comparisons use the clearly stated specimen, model or nominal measurement.
Sun
Our star, modelled with the IAU nominal solar radius. “Surface” means the visible photosphere. The core is much hotter; this is not a solid surface.
The marked mass is calibrated. Unmeasured illustration details are representative.

Why these numbers?
The visual compares mass with mass. The records below preserve each value’s basis and caveats.

- Comparing
- Mass ↔ Mass
- 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.
- Sun is labelled approximate; treat the displayed value as a comparison anchor rather than false precision.
