What planet has a density less than water?

Answer 1

Saturn has a density of 0.7 g/cm^3. This is less than the density of water, which is 1.0 g/cm^3.

Answer 2

Saturn has an average density less than water, about 30 percent less to be exact. If you could get a big enough tub of water, the planet will float in it.

Answer 3

Saturn meets that criteria, but the problem is Saturn is cold as all get out and would freeze any water you tried to float it upon in a heartbeat. I chuckled at the old chestnut response about leaving a ring around the tub. Har, Har. There are "real" people out there after all.

Reminds me of the feller that asked when we were going to send a Lunar Lander to Saturn....Heh, Heh, Heh, just a little detour, right?

Answer 4

The mean density of Saturn is 700 kg/m^3; all the rest are at least 1300 kg/m^3.

Answer 5

Saturn. It is a smaller gas giant, and its average density is less than water.

Saturn would float in a bathtub.

Answer 6

The gas giants (Neptune, Uranus, Saturn, And Jupitur) are concept/primary to be much less dense than water. The humorous element is that it somewhat is expected that deep interior neptune, father than we are able to pass, there is meant to be an ocean of water!

Answer 7

There's an old chestnut. My astronomy professor always joked that if you had a bathtub big enough, you could float Saturn in it -- but it would leave a huge ring.

Answer 8

Saturn!!!

If you could put Saturn in a bathtub, it would float.

The big ones

Answer 10

Pretty much all the gas giants
