If you collected all of Earth’s water into a sphere, how big would it be?

Our water sphere would have a diameter of 1,385 kilometers (about 860 miles), and span the distance from Salt Lake City, Utah to Topeka, Kansas. A sphere this far across would have a volume equal to about 1,386 million cubic kilometers (roughly 332,500,000 cubic miles).

By comparison, the Earth measures a staggering 12,256 km in diameter, dwarfing the little blue sphere — a “little blue sphere” that contains more than enough water to cover over 70 percent of our planet’s surface, and fill every life form on Earth with H₂O molecules. (Those looking for a similar size comparison at home can use a basketball to represent the dry Earth, and a nickel to illustrate the diameter of our water sphere.)
