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... :)
Neptune is less dense than the Earth. Neptune's density is 1.638 grams per cubic centimeters and Earth's density is 5.513 grams per cubic centimeters.
Neptune is a gas giant. The inner rocky worlds (Mercury, Venus, Earth, Mars) are all denser than any of the outer gas giants.
Neptune is the most dense.
Earth for comparison has a density of 5.515 g/cm3
Uranus is a gas planet (ice giant) and will be less dense than any of the "rocky" planets.
Uranus has a density of 1.27 g/cm³ whereas the Earth has a density of 5.515 g/cm3.
Yes. The gravitational force of Neptune is 11.15m/s2, which is greater than Earth's gravity which is 9.81m/s2.
Yes.
neptune's surface gravity is 1.14 times stronger than that of earth...but it is a planet made by gas..so you won't feel this gravity as you will sink in through gaseous layer
Surprisingly the gravity at Neptune's nominal "surface" is only 14% greater than it is on Earth. This is because, while Neptune is 17 times more massive than Earth, it is also nearly 4 times Earth's diameter, putting the "surface" farther from the center of mass.
Neptune has slightly more gravity than Earth. It is believed that the gravity is 17% greater than Earth's.
Jupiter and Neptune are the only planets in our Solar System that have more gravity than the Earth. Jupiter's gravity is about 236% that of the Earth, and Neptune's gravity is about 112% that of the Earth. Edit: Because of uncertainties and different definitions you can get data that says Saturn and/or Uranus also have slightly stronger gravity than Earth's.
It is estimated that the gravity on Neptune is 12% greater than Earth
it is stronger
Neptune's gravity is stronger, and is equal to 11m/s2.
Yes it is.
yes
It isn't clear what you mean with "stronger or weaker". Neptune's gravity is stronger than that of Earth, if that's what you mean, since Neptune has a larger mass.
About 17 percent stronger (it's more massive).

Neptune-114% Jupiter-254%
No, because of the great volume the gravity on Neptun is barely stronger than on the Earth.
