Would Saturn float in a big enough bathtub?
Yes, as a density comparison. Saturn's average density is lower than water, though no bathtub could hold it.
FLOATING?
The Claim
Saturn is less dense than water.
The Answer
NASA lists Saturn's average density as below one gram per cubic centimeter. The popular bathtub version is playful shorthand for density, not a practical scenario.
Why This Is Surprising
It sounds like the kind of claim that races around social feeds without context. The source trail matters because the best version of the wonder is the verified one.
How We Checked It
We looked for an authoritative primary source, checked the wording against at least one credible secondary source when available, and recorded the last review date.
