What planet would float on water?

Answer 1

Saturn

Volume 8.27×10^14 km^3 (763.59 Earths)
Mass 5.6846×10^26 kg (95.162 Earths)
Mean density 0.6873 g/cm^3 (less than water)

Answer 2

I doubt any would. What we see as a gas giant very likely has a dense core that creates enough gravitaional force to keep the gas around it from escaping into space. While the average density of the planet, including it's atmosphere, may be lower than water, the core's density is likely to be greater than lead because of the intense gravity. If it were possible to place that core in an earth ocean, it would sink and the gas would become part of the earth's atmosphere. Earth would then become a gas giant.

Answer 3

Saturn. The average density of the planet is less than water, so if there were an ocean large enough to hold it, it would float.

Answer 4

A newly discovered planet has one-quarter the density of water and would float if placed in a bathtub large enough to hold it.

"It's lighter than a ball of cork," said study team leader Gaspar Bakos of the Harvard-Smithsonian Center for Astrophysics (CfA).

Called HAT-P-1, the planet is about half as massive as Jupiter but about 1.76 times wider—or 24 percent larger than predicted by theory.

The finding, to be detailed in an upcoming issue of Astrophysical Journal, could force a revision of planet formation theories as astronomers struggle to explain what is causing the planet to swell.

HAT-P-1 belongs to a class of planets called "hot Jupiters" that are so named because they orbit much closer to their stars than Jupiter does to our Sun, despite being roughly the same size.

Answer 5

Saturn it has a very low density

Answer 6

Saturn because it has a very low density.
