What else can I help you with?
Is Mars a low density cloud of gas or something more substantial?
Something more substantial - a planet quite similar to Earth, in the sense that it has a solid surface. Mercury, Venus, and Mars are similar to Earth, in that they have a solid surface. Jupiter, Saturn, Uranus and Neptune are gas giants. They do not have a solid surface like Earth.
Is Neptune more gaseous than Earth?
Yes, Neptune is more gaseous than Earth. Neptune is a gas giant made mostly of hydrogen and helium, while Earth is a terrestrial planet with a solid surface and a thin atmosphere composed mainly of nitrogen and oxygen.
Does neptune have high or low gravity?
Everything has gravity. Some examples include: every planet every star every moon every fish every speck of dust every drop of beer every shred of lint
Is there more or less gravity on Neptune than on Earth?
If Neptune had a solid surface, it would have slightly more gravity at that point than on the surface of the Earth. But it is a gas giant, with a deep atmosphere that becomes crushingly dense and incredibly hot as you near the rocky core. At the point where the atmospheric pressure is equal to the sea level pressure of Earth, the gravitational attraction is about 14% more than on Earth, and the associated acceleration would be about 12% more. Neptune has 17 times the mass of Earth, but the location of this measurement is more than 20,000 km from its center, and gravity decreases as you move farther from the center of mass.
Does Neptune have a weaker gravity force than Earth?
As you may know, gravitic force is measured from the center of the body or mass. So . . . Nepune is 17 times more mass-ive than Earth (heavier), but any point on its surface is 3.8 times farther from Neptune's center than a similar location on Earth. Gravitic force lessens by 4 times when you move another mass 2 times farther away from it. The result is that, despite being huge in comparison to Earth, Neptune's force of gravity at its surface is only 1.14 times the force of gravity on earth's surface. So, if you weighed 150 pounds on earth, you would weigh 165 pounds on Neptune, if you could manage to stand on its surface. (Its surface is not solid like Earth's)
How much stronger is Neptune's gravity than earth's?
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.
How much more gravity is there on Neptune than there is on Earth?
The 'surface' acceleration of gravity on Neptune is 11.15 m/s2 . That's about 14% greater than on the Earth's surface. If you weigh 200 pounds on Earth, then at the depth in Neptune's gaseous mantle where the pressure is equal to Earth's sea-level atmospheric pressure, you'd weigh about 228 pounds.
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.
Gravity of Neptune compared to earth?
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:The mass of the planet or moon.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.
What is naeptune's surface gravity compared to earth?
When compared to the surface gravity of Earth, Neptune has approximately 14% more gravitational pull. This is a small difference when compared to other planets in the solar system.
Is there more or less gravity on Neptune then on earth?
Neptune has slightly more gravity than Earth. It is believed that the gravity is 17% greater than Earth's.
Is there any planet having more gravity than the earth?
In our solar system, Neptune, Jupiter and Saturn all have higher surface gravities than earth.
