Rankle #48 answer: solar system rocky planets (smallest to largest diameter)

The answer

Rank by solar system rocky planets (smallest to largest diameter)

1. 1Mercury4,879 km
2. 2Mars6,792 km
3. 3Venus12,104 km
4. 4Earth12,756 km

Why this order

Ranked smallest to largest diameter, Mercury (4,879 km) goes at the top and Earth (12,756 km) at the bottom.

The closest call is Venus (12,104 km) against Earth (12,756 km), only about 5% apart. That is the swap most likely to cost a point.

The biggest gap is between Mars and Venus, about 78% apart, so that boundary should be the easiest part of the order to get right.

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