What else can I help you with?
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.
What percentage of earths density does Neptune have?
None. There is no water on Neptune.For water to form, a planet needs volcanic activity. The the steam from volcanoes evaporates and falls back down to the planet, forming lakes and oceans.This is impossible on Neptune, because Neptune:Is a gas giant. It has no surface or plates. Which means no volcanoesIt is too far from the sun for water to remain in liquid stateNeptune looks like an ocean planet because of the methane gasses in its atmosphere which reflect the blue spectrum from the dim sunrays back into space.
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.
Which is heavier Neptune or Earth?
because neptune has more gravity than earth, so, idf you were to go there, the atmosphere of mathane, hydrogen, and helium would puch down on you and you would weigh more.
Does Neptune have a mean density of 1.2?
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.
What planet may have a density of 0.69 g cm3?
Neptune is the planet with a density of about 0.69 g/cm³. Its density is lower than Earth's due to its composition, which includes a large amount of gases like hydrogen and helium.
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... :)
