📍 Stand back on the lawn to get the whole figure in frame — at thirty feet it is nearly four times the size of the Sun you started at, which is the last joke this walk plays on you. The real Neptune would be a marble.

About this place

3.6 inches of Neptune, 5.18 miles from an 8.5-foot sundial. Everything between here and the Adler is empty space at this scale — and the emptiness is the part worth walking for.
