21.0975 kilometres
The quantity is exact as entered. Comparisons use the clearly stated specimen, model or nominal measurement.
Neutron star
A 20 km, 1.4 solar-mass teaching model. The precise radius depends on stellar mass and the uncertain behaviour of dense matter.
The marked diameter is calibrated. Unmeasured illustration details are representative.

- Comparing
- Length ↔ Diameter
- Relative size
- 21.0975 kilometres is larger on this measurement by a factor of about 1.05. 21.0975 kilometres's selected measurement is approximately 5.49% greater than Neutron star's.
How to read the visual
The labelled spans and stored measurements determine the scale; unmeasured illustration details do not.
- Neutron star is labelled representative; treat the displayed value as a comparison anchor rather than false precision.
