The density of Neptune is 1.638 kg/m3.
Answer
Neptune's density is 1.638 g/cm³. That means that in every cm cubed it weighs 1.638 grams.

∙ 11y agoNeptune does not have any oceans. Or water for that matter.
Neptune is a gas giant. Which means it doesn't even have a solid surface.
Neptune looks like an ocean because of the blue light spectrum from the dim sunlight being reflected off the methane gasses in the atmosphere.
It is impossible for water to exist on a planet that doesn't have a solid surface. It is possible for it to have ice particles however.

Does Neptune have a mean density of 1.2?
No. Neptune's mean density is 1.638 g/cm³.
What planet is the smallest of the gas giants?
Of the four gas giants; Jupiter, Saturn, Uranus and Neptune, Neptune is the smallest. Uranus is the least massive though, bigger than Neptune but lower in density and mass.
Would Neptune float or sink in water?
There is no exact answer to this. If you could somehow get a large enough body of water to test it in, many of the gases in Neptune's atmosphere (e.g. ammonia) would rapidly dissolve in the water. Also Neptune is likely to have a dense stony or metallic core under its thick atmosphere, so different parts of Neptune might do different things. However if Neptune had a homogeneous, insoluble in water, not chemically reactive composition, a sample of it would have a density less than the density of water an so would float, but Neptune does not have such a composition.
What planets have lower density?
Saturn, Uranus, Jupiter, and Neptune have the lowest densities. Generally, the gas and ice giants have the lowest densities. Saturn has the lowest density of 0.687 g/cm³ which is less dense than water, whereas Neptune has a density of 1.638 g/cm³ The Earth for comparison has a density of 5.515 g/cm3
How much does neptune the planet weigh?
The volume of Neptune is 6.254 E13 cubic kilometers. The mass of the planet is 1.0243 E26 kilograms, giving it an average density of 4.638 grams per cubic centimeter.

No. Neptune's mean density is 1.638 g/cm³.
Does Neptune have any density?
Of course. Anything that is material has some degree of density.
What planet is the smallest of the gas giants?
Of the four gas giants; Jupiter, Saturn, Uranus and Neptune, Neptune is the smallest. Uranus is the least massive though, bigger than Neptune but lower in density and mass.
Density of Neptune?
1.638 g/cm (then the little three thing above cm)
What are Three planets that are relatively large gaseous and low of density are?
Jupiter, Saturn, & Neptune.
What is Neptune's atomsphere?
Neptune has a low density,only about 1.6 times the destiny of water. Neptune is the eighth planet from the biggest star "The Sun". Neptune revolves arround the sun in a nearly circular orbit at a mean of about 2.8 billion miles{49 kilometers}.

Does Neptune have little gravity?
No. Neptune is far more massive than Earth, but its lower density also gives it a much greater radius. As a result, gravity at Neptune's "surface" (defined as where pressure is 1 bar) is about 14% greater than it is on Earth.

Does neptune have stronger gravity than earth?
This is a question that arose from another question I asked earlier today, but why is Neptune more dense than Uranus despite being close to the same size, but further from the sun? As I understand it, heavier elements should have been concentrated closer to the sun during the formation of the planets. The only theory I have heard is that Neptune somehow formed closer to the sun than Uranus, and drifted to a further orbit, but I received no explanation as to how that would happen. Another theory I heard is that it formed from a larger amount of less dense material, and that mass compressed it, but as I understand it, larger volumes of less dense materials make for larger, thus less dense planets. For example, Jupiter despite it's huge mass is still less dense than any of the inner four planets. hop this is what you needed... :)
What is the average density of Pluto?
The average density of Pluto is 2.03 g/cm3. This figure differs significantly from the 1.64g/cm3 density of Neptune or the 687.00 kg/m3 density of Saturn.
