Rankle #68 answer: diameter (smallest to largest)

The answer

Rank by diameter (smallest to largest)

1. 1Mercury4,879 km
2. 2Mars6,779 km
3. 3Earth12,742 km
4. 4Jupiter139,820 km

Why this order

Ranked smallest to largest, Mercury (4,879 km) goes at the top and Jupiter (139,820 km) at the bottom.

The closest call is Mercury (4,879 km) against Mars (6,779 km), about 39% apart. That is the swap most likely to cost a point.

The biggest gap is between Earth and Jupiter, about 11 times apart, so that boundary should be the easiest part of the order to get right.

From top to bottom the figures span a factor of roughly 29.

These are the figures the game reveals after you submit. They are rounded; only the order is scored.
