Both marked spans share one linear scale. Artwork keeps its proportions; poses and surface detail are illustrative.

A little perspective

The mean diameter of Mimas is about 1.98 times the length of 200 kilometres.

Measurements, assumptions & sources +

The quantity is exact as entered. Comparisons use the clearly stated specimen, model or nominal measurement.

Saturn’s moon Mimas is about 396 km across and dominated visually by Herschel crater. The diameter is a mean for an imperfect sphere.

The marked mean diameter is calibrated. Unmeasured illustration details are representative.

Comparing: Length ↔ Mean diameter
Relative size: Mimas is larger on this measurement by a factor of about 1.98. Mimas's selected measurement is approximately 98.2% greater than 200 kilometres's.

The labelled spans and stored measurements determine the scale; unmeasured illustration details do not.

Mimas uses a 396.4 km central value within a recorded range of 395 km–398 km.
Mimas is labelled approximate; treat the displayed value as a comparison anchor rather than false precision.
