It is impossible to really find out because we cannot measure the mass and volume of a planet, but the most possible is gas planets because gas should not be too dense.

Saturn, because it has an extremely low density, can "float on water if you can find a pool big enough". ~Ripley's Believe it or Not 2010 Special Edition.

Saturn, although you'd have to find a way to keep the atmosphere on it.

How light is the planet Saturn?

So light it would actually float on water.


Which planet is less dense and can float?

Saturn is a gas planet, and if it were possible to place it in water it would float. Not sure if the rings would float, but, the planet itself would.


Which planet could float on a giant planet?

The low density of Saturn would allow it to float in liquid water.


What planet is so light it would float in water?

SATURN.


Does Anorthite sink or float in water?

It will float. Its a rock. It actually depends on how much water you have, if you you tried float it in the ocean, it would obviously sink. But if you tried to float it on a gladd or bowl or water, it would float,


Which planet is known for system of rings and would float in a tub of water?

Saturn. The planet is less dense than water.


Would Uranus float in water?

No, the density of Uranus is 1.27 g/cm3 (the density of water is 1.00 g/cm3), therefore Uranus would sink. The planet that would float in water is the planet Saturn which has a density of 0.687 g/cm3.


Which planet is the least dense and would float?

Saturn is that planet. It's less dense than water so would float in theory, but it's not a very practicable idea.


What what would happen to Saturn if it were placed in water?

Theoretically, the planet Saturn would float when placed in water because it has an average density that is less than the density of water. On the other hand, there is probably not enough water in the solar system to permit the experiment to be performed. If you choose not to consider the planet as a whole, the atmosphere would float on the water but the rocky core would sink like a stone.


What planet would float on water in a giant bath tub?

Saturn..... amazing isn't it!


Which planet is the the only planet that would float on water?

Saturn. Obviously it's not a very practical idea, but Saturn is less dense than water.


Would Saturn float?

Saturn (the planet) would float if you could find anything large enough for it to float in. The density of Saturn is 0.687 g/cm³ which is less than water. However, the density of Saturn (the planet) is always calculated as the "mean density", indicating that the mass of the core, water, and gasses are all combined to provide the total mass of the planet, and the volume, including the gas mantle is used to calculate mean density. Naturally the gas mantle will float, since it is significantly less dense than water, but if the planet were placed in a theoretical container of water, the gas would no longer be a significant part of the process, and the core of the planet would sink. So... it depends on how you're deciding whether the planet will float. Are you putting a large balloon around it then putting it into the theoretical container of water? Yes, it will float if that's what you're doing. But if the gas of the planet is allowed to act as a gas, everything changes... you decide. Saturn (the vehicle) would float briefly, while the windows and doors are closed, but as air is displaced, water would fill the inside of the vehicle and it would sink. If you wanted to fill the interior with beach balls or something else that would hold air... it would probably float.
