Field notes
The comparison view reports diameter, a side-by-side scale, how many smaller bodies fit across the larger one, and the size ratio. A separate scaling control translates a comparison into a size the visitor can choose, while the object directory gives individual diameters and the page offers a five-step guided journey.
