Rankle #30 answer: solar system object distance from Sun (nearest to farthest)

The answer

Rank by solar system object distance from Sun (nearest to farthest)

1. 1Mercury57.9M km
2. 2Earth149.6M km
3. 3Neptune4.5B km
4. 4Pluto5.9B km

Why this order

Ranked nearest to farthest, Mercury (57.9M km) goes at the top and Pluto (5.9B km) at the bottom.

The closest call is Neptune (4.5B km) against Pluto (5.9B km), about 31% apart. That is the swap most likely to cost a point.

The biggest gap is between Earth and Neptune, about 30 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 100.

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

Difficulty: medium, judged by how close the tightest pair is.
