Gravity of Neptune compared to earth?

Answer 1

Neptune has 17 times the mass of Earth, but it is also larger, and gravity diminishes the farther you are from the center of gravity. So, if it had a solid surface, Neptune's surface gravity would only be slightly higher than Earth's (14% greater or 1.14 G). The gravitational acceleration at the point where its atmospheric pressure is equal to Earth's at sea level is 11.15 meters per second squared.

The pull of gravity on the surface a planet or moon depends on two things:

1. The mass of the planet or moon.
2. How far its surface is from the center of gravity.

The related links include a good website that shows you the comparison between the pull of gravity (how much you would weigh) on the surface of all the planets.

Answer 2

Surprisingly, it is only about 1.14 G (Earth=1G)!

This is because its "surface" (the point where its atmospheric density is equal to Earth's at sea level) is more than 20,000 km from its center. So despite having a mass 17 times that of Earth, Neptune's pull of gravity would only be about 14% more at that point. Neptune's solid core is deep within a dense, slushy atmosphere that transitions from a dense gas to an extremely hot mix of ammonia and water.

Answer 3

3 earths would be able to fit inside Neptune so in comparison Neptune's size is big compared to Earth

Answer 4

Neptune's gravity is about 1.19 times the gravity on Earth. An object weighing 100 kg on Earth would weigh 119 kg on Neptune.

Answer 5

Neptune's gravity is 1.14 times greater than Earth's gravity. A person weighing 100 pounds on Earth would weigh 114 pounds on Neptune.

Answer 7

At their respective surfaces, 14% greater on Neptune than on Earth.
