This is a composite image of Saturn's moon Phoebe comparing it in size with the Netherlands. Phoebe is, from top to bottom, 220 kilometres in height and 110 kilometres wide.
The whole image of the Netherlands is 154 kilometres left to right, and 225 kilometres top to bottom. From the top of the fourth island to Hoek van Holland (north of where the delta starts), this distance is 220 kilometres.
But from Maastricht in the south (not in the picture) to its northernmost point, the Netherlands is 300 kilometres in length in total.
