The Only Planet That Can Float On Water Is

Saturn, the second-largest planet in our solar system, is unique for its ability to float on water due to its low density of approximately 0.7 grams per cubic centimeter, which is less than that of water at 1 gram per cubic centimeter. This gaseous giant, primarily composed of hydrogen and helium, would remain buoyant if placed in a sufficiently large body of water, unlike the other planets in our solar system.
