Does neptune have stronger gravity than earth?

Answer 1

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... :)

Answer 2

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.

Answer 3

Neptune is a gas giant. The inner rocky worlds (Mercury, Venus, Earth, Mars) are all denser than any of the outer gas giants.

Answer 4

Neptune is the most dense.

• Uranus has a density of 1.27 g/cm³
• Neptune has a density of 1.638 g/cm³

Earth for comparison has a density of 5.515 g/cm3

Answer 5

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.

Answer 6

Yes. The gravitational force of Neptune is 11.15m/s2, which is greater than Earth's gravity which is 9.81m/s2.

Answer 7

Yes, Neptune has a stronger gravitational pull than Earth due to its larger mass. Specifically, Neptune's gravity is 11.15 m/s² compared to Earth's 9.81 m/s².

Answer 8

Yes.
