Both marked spans share one linear scale. Artwork keeps its proportions; poses and surface detail are illustrative.
A little perspective
The length of 26.2 miles is about 1.87 times the representative mean diameter of Phobos.

26.2 miles
The quantity is exact as entered. Comparisons use the clearly stated specimen, model or nominal measurement.
Phobos
Mars’s larger moon is irregular, about 27 × 22 × 18 km. The 22.533 km comparison diameter is representative rather than a spherical edge.
The marked representative mean diameter is calibrated. Unmeasured illustration details are representative.

Why these numbers?
The visual compares length with representative mean diameter. The records below preserve each value’s basis and caveats.

- Comparing
- Length ↔ Representative mean diameter
- Relative size
- 26.2 miles is larger on this measurement by a factor of about 1.87. 26.2 miles's selected measurement is approximately 87.1% greater than Phobos's.
How to read the visual
The labelled spans and stored measurements determine the scale; unmeasured illustration details do not.
- Phobos uses a 22.53 km central value within a recorded range of 18 km–27 km.
- Phobos is labelled approximate; treat the displayed value as a comparison anchor rather than false precision.
