Some people have claimed that Russia’s land mass is larger than Pluto. Let us take a look at this claim.
When NASA’s New Horizon’s mission buzzed by Pluto in July 2015, the decades-long debate about the dwarf planet’s size was finally answered.
In terms of diameter, Pluto was found to be 2370 kilometers (1473 miles) across, which 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 4000 km.
Using previous estimates, Russia edged out Pluto, at 17,075,200 square kilometers, while Pluto was thought to be 16,647,940 square kilometers.
After the New Horizons mission, Pluto was found to be slightly larger than estimated, making its surface area 17,646,012 square kilometers, which is larger than Russia.
