Not always. The force of gravity is given by Newton's Law of Universal Gravitation:
F=(Gm1m2)/r2
So if a planet had twice the mass of the earth, and the same radius, gravity would be twice as strong.
However, if you had a huge planet that weighed the same as the earth (let's say it had a radius 3x greater), then gravity would be 9 times weaker at the surface.
The reason big planets like Jupiter have so much gravity is becuase they have A LOT more mass than the earth does.

∙ 12y agoyes they do, for example, Jupitar has more gravity than any other planets because it is bigger. And Pluto has less gravity than any other planets because it is smaller. The bigger the size, the more gravity it has.
Wiki User
∙ 13y agoMass is related to gravity. The more mass you have, the more gravity. Even a small moon or rock will have gravity, but the force of gravity is very weak, so you wont notice it until you have something quite big.

∙ 14y agoIt would depend on the mass; if the small planet were very dense and the large planet were fairly light, the small planet could have higher gravity. In fact, if the large planet and the small planet have the SAME mass, the smaller planet will have higher gravity, because the distance from the surface to the center would be lower.
But in general, a larger planet will have a higher gravity than a smaller one - because the larger planet will have higher mass.
But here's a real-world example. Earth has a mass of 5.97e24 kg and a diameter of 6378 km, while Saturn has a mass of 5.68e26 kg (90 times more!) and a diameter of 60268 km (10 times larger). Saturn's "surface" gravity is 91% of Earth's.
Gravitational force increases as the mass of the body increases - and decreases by the SQUARE of the distance! So to have the same surface gravity, a planet that is 10 times larger must have 100 times more mass.

Wiki User
∙ 11y agoThe strength of gravity of an object is directly proportional to its mass. A larger planet will generally have a greater mass.

Why do the gas giants have more moons than the terrestrial planets?
They are larger and so they have more gravity.
Does larger planets have more gravity than the earth?
It is more accurate to say that more massive planets have stronger gravity. If a planet had the same mass as Earth but a larger radius (i.e. it is less dense) surface gravity would be weaker, as the strength of gravity depends on both an objects mass and the distance from its center.
Is mass larger on bidder planets or smaller?
Mass does not change with gravity. Weight increases on BIGGER planets and decreases on smaller planets.
Why do gas planets have more moons than rocky planets?
Gas planets have mor planets then rocky planets because rocky planets are like earth. Gas planets are just difrent in there own way. If im wrong tell me but im pretty sure that's why. they are larger so the gravity captures more satalites
Which has a more powerful gravity a small planet or a large planet?
It would depend on the mass of the planets. The surface gravity of a planet is directly proportional to its mass and inversely proportional to the square of its radius. If two planets have the same mass but different sizes, the smaller planet will have stronger gravity because the surface is closer to the center of mass. Conversely, if two planets are of the same size, the one with more mass will have stronger gravity. Since larger planets usually have more mass than smaller ones they usually have stronger gravity, though not always.
Why do gas giants have more moons the terrestrial planets?
They are larger and so they have more gravity.
Why do the giants have more moons than the terrestrial planets?
They are larger and so they have more gravity.
Does regular planets have weak gravity?
Generally speaking, the bigger or more massive a planet it, the more gravity it has, since gravity and mass are related. the small planets such as Mars and Mercury have a weaker gravity, while the larger planets have a strong gravitational field.
Why do larger planets have more satellites?
Because since the outer planets are bigger then they have more gravity, drawing more objects toward it.
Why do larger planets have more natural satellite?
Because since the outer planets are bigger then they have more gravity, drawing more objects toward it.
Why do these gas giants have more moons than the terrestrial planets?
They are larger and so they have more gravity.

Why planets do not move away through their orbit?
GRAVITY... gravity means that objects are "attracted" to other objects, and the larger the object, the more GRAVITY will "attract" the object. The sun's gravity is too large for the planets to overcome.
How gravity affects us on different planets?
The larger the planet is, the more amount of gravity you will get. The smaller the planet is, the less amount of gravity you will get.
What is the effect of gravity on the planets?
simple, the larger the planet, the greater the force of gravity.
Which planets have gravity larger than earths?
Neptune and Jupiter
