Both marked spans share one linear scale. Artwork keeps its proportions; poses and surface detail are illustrative. A ruler represents the selected distance or unrolled circumference; it is not the physical size of the pictured body.

A little perspective

The distance of Distance to the galactic centre is about 7.97 times the length of 1 kiloparsec.
