A little perspective
Seine vs Enceladus: length comparison
The main-channel length of the Seine is about 1.54 times the mean diameter of Enceladus.
The Seine is a river in northern France that passes through Paris and flows into the English Channel.
Enceladus is a natural satellite of Saturn, with an icy surface and plumes of water vapour erupting from its south pole.
Both rulers start at the same zero and share one linear scale. Artwork keeps its original proportions.
