The statement that "Saturn can float on water" is based on its average density. Density is the measure of how much mass is packed into a given volume, calculated as:
Density
=
Mass
Volume
Density=
Volume
Mass
Saturn’s Density:
Saturn has an average density of 0.687 g/cm³, which is less than water’s density (1 g/cm³). This makes it the least dense planet in the solar system.
What Floating Means:
An object floats in a liquid if its density is lower than the liquid’s density. Since Saturn’s average density is lower than water’s, in theory, it could float.
Why It’s Not Practical:
Saturn is huge: Its volume is over 760 times that of Earth.
There’s no bathtub big enough: To float, Saturn would need an ocean large enough to hold it—something impossible on Earth.
Not a solid object: Saturn is a gas giant, mostly made of hydrogen and helium. If placed in water, it wouldn’t stay intact but would likely compress and react with the water.
So, while Saturn theoretically has a low enough density to float, in reality, this is just a fun fact about its composition rather than a physically possible scenario.
