Relative to the Earth, any planet with less mass density or volume. If a planet is smaller in all of these respects gravity will decrease. a lot of times with only two and very occasionally with only one. the planets in our solar system that do are venus mars and Mercury.

∙ 11y agoLess density than Earth have the Jovian or gas planets:
Jupiter, Saturn, Uranus, and Neptune.
The gas planets are composed primarily of hydrogen and helium and generally have low densities, rapid rotation, deep atmospheres, rings and lots of satellites.
Also, Mercury Venus and Mars are less dense than Earth. So you can see that of all the planets, Earth is the densest.

∙ 9y agoEarth has the highest average density of any planet in the Solar system, so "all of them".
There are extra-solar planets with densities far higher than Earth's. Theory says that Jupiter is just about as big as it's possible for a body that isn't a star to be ... when you add mass to something the size of Jupiter, it doesn't get bigger, it gets denser, until the density becomes so high that compression ignites fusion in the core (which then heats the body up and causes it to expand). Planets intermediate in mass between Jupiter and a brown dwarf star (about 80x the mass of Jupiter) can be much denser than Earth is; the exoplanet COROT-3b is about the same diameter as Jupiter but over 20x more massive, so it's over four times as dense as Earth.

Would the gravity on the planet Mercury squash someone?
No. The gravity on Mercury is less than half that of Earth.
What planet has one sixth gravity less than earth?
It could be mars.
Would a smaller planet than earth with the same shape and size have more gravity?
If the planet is smaller, then it can't have the same size. If you assume that a smaller planet has the same density as Earth (and therefore less mass), its surface gravity will be smaller. If you assume that a smaller planet has the same mass as Earth (and therefore more density), its surface gravity will be greater. This is because we would be closer to the planet's center - or to the planet's matter in general.
Will you float away on the planet mercury?
No. Mercury's surface gravity is less than that of Earth, but it will still hold you to the surface.
Is the farther a planet is from the sun have less gravity it has?
No. The strength of gravity on a planet depends on its size and mass.
Which planet has less gravity earth or mars?
Mars has less gravity.
Does planet Uranus have more or less gravity than earth?
The "surface gravity" is less on Uranus.
Is there more or less gravity on your planet than on earth?
No. My planet (and presumably yours as well) is Earth.
Why does this planet have less gravity than the Earth?
because it has less mass.
How much time less then gravity of the moon as compare to the earth?
moon's gravity is (1/6)th of the earth's gravity
What planet has a gravity pull of less than half of earth?
the sun
Would the gravity on the planet Mercury squash someone?
No. The gravity on Mercury is less than half that of Earth.
What planet has one sixth gravity less than earth?
It could be mars.
Why is there gravity on earth but almost none in space?
On Earth, gravity comes from the planet. The farther you go into space and away from Earth, the less gravity there is. Until you get near an large object, like a star, or a planet, or a moon, or a black hole. Then you will feel the pull of gravity again.
Why does the weightyou havechange from planet to planet?
the bigger the planet the more gravity it has, the smaller the planet the less gravity it has, so if you weigh, lets say, 5 stone here on earth, you go to Jupiter and you weigh alot more as theres more gravity pulling on you, go to mercury and you'll weigh less as theres less gravity pulling on you.
Is mercurys gravity stronger than earths?
Planet Mercury and Planet Earth are both rocky planets. But Mercury is much smaller than Earth, so has much less force of gravity. Your answer is "No".
Why the gravity of some planet is less or more than the gravity of the Earth?
More Mass = Greater "surfacegravity".But also alarger diameter = Less "surface gravity".So, for example, if the planet is larger than Earthand has more mass then the gravitational force at its surfacecould be greater or lessthan Earth's.
