Pluto Is About the Same Surface Area As Russia

Pluto was discovered in 1930 and was originally classified as the 9th planet in our solar system. In 2006 the International Astronomical Union demoted Pluto to a dwarf planet, making it one of the largest dwarf planets.

In terms of diameter, Pluto is only 2,390 km across. For comparison, that's about 70% the diameter of the Moon and only about 18% of Earth's diameter. It would easily fit within Russia's largest east-to-west width of 10,000 km. It would also fit within the largest north-to-south size of 4,000 km.

In terms of volume, Pluto has 6.39 x 109 km3. Even though it sounds like a huge number, it's only 0.59% of Earth's volume. Pluto's mass is 1.3 x 1022 kg, about 18% the mass of the Moon and only 0.2% of Earth's mass. Needless to say, Pluto doesn't have much mass, having only about 6.7% of Earth's gravity.

The surface area of Pluto, at 16,647,940 km2 (6,430,000 mi2), is about 3.3% of Earth's surface area. Pluto is about the same surface area as Russia, the largest country by land mass on Earth, with a surface area of 17,098,322 km2 (6,601,699 mi2).
