What is the surface area of Pluto?
18 million km². Don't let the 'dwarf' label fool you—its surface area is even larger than Russia, the largest country on Earth!
How close would your guess have been?
In the game we ask it like this: “What is the surface area of Pluto, the planet that was demoted, in million km²?”
