If a planet has 4 times the density but half the diameter of earth is it's gravity stronger or less?
No, the gravity of this planet will not be greater than that of earth. If the new planet has a mass equal to that of earth, its total gravity will be the same. There is a little ambiguity regarding 4 times earth density and half the earth's diameter if the idea is to keep the mass of this proposed planet the same as the earth. But setting that aside and assuming that the mass of the new planet is the same as earth's, the gravimetric field will be the same. Gravity is proportional to mass, and identical mass yields identical gravity. Now to the good part! The surface gravity of the new planet will be considerably higher than the surface gravity of earth. Both planets have the same mass and the same gravity, but a person standing on the surface of the new planet will be experiencing a whole lot more force pulling on him. All the mass of the new planet is beneath this person, but he's a lot closer to the center of gravityand will weigh a whole lot more.
What else can I help you with?
If two planets have the same mass but different diameters Which planet has the stronger gravity at its surface?
The smaller diameter. Because the formula is G* m1 * m2 / r^2 . The gravity is negatively correlated with square of the distance between mass centers of the objects. When the distance increases the gravity decreases.
What planet has stronger or weaker gravity than earth?
All of them do. There's no planet where the gravity is the same as on Earth.
What are the characteristics that cause a planet to have less gravity?
The force due to gravity of a planet is dependent on the mass of that planet (and to a lesser extent the radius/diameter). If a planet is less massive then it will have a lower gravitational force.
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.
The earths gravity compared to Saturn's?
Earth's gravity is significantly stronger than Saturn's. The gravitational acceleration on Earth's surface is about 9.81 m/s², while Saturn's gravity is approximately 10.44 m/s². However, because Saturn is a gas giant with a much larger diameter, its gravitational pull is felt differently; you would weigh less on Saturn due to the difference in density and the lack of a solid surface. Overall, while Saturn's gravity is slightly stronger, the experience of gravity differs due to the planet's composition.
Is gravity on a planet affected by the mass on a planet?
Yes, but also on its diameter. Or density if you prefer.

Is the gravity force on the other planets stronger or weaker than the force on earth?
It varies. It is stronger on some planets and weaker on others. The strength of gravity on any planet depends on its mass and diameter.
How would your weight differ if you went to a planet twice the diameter of earth?
It depends upon the density of the planet. Another Answer: A person's weight is their Mass multiplied by the Force of Gravity of that particular planet. Your Mass should never change unless you gradually become skinnier or the opposite. So it prominently depends on the Force of Gravity not necessarily the diameter of the planet.

What planet is giant with strong gravity?
Well if you're speaking about our solar system, Jupiter is the biggest giant planet with strongest gravity.

Which planet has the most greatest gravity?
Jupiter has the strongest gravity. The bigger the planet, the stronger the gravity. The moon is kind of small, so it's gravity is weaker.

What features of a planet affect gravity?
mass and density
What dictates gravity density or size?
The force of gravity is determined by (a) the masses involved, and (b) the distance between the masses. Of course, in the case of a planet for example, you can determine the mass if you know its average density and its size. Note that for a homogeneous sphere, the force of gravity on an object outside the planet is the same as if all mass were concentrated in the center.
