Saturn passes the float test. Sort of.

Here's the strange part.

Saturn wins the imaginary bath-time contest. Its average density is about 0.7 grams per cubic centimetre, below water's roughly 1. That is the whole trick behind the claim that it would float. It is a memorable way to compare densities, not a realistic proposal to lower an enormous gas planet into an even larger tub. (NASA StarChild)
