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 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.
Does a larger planet have greater or less acceleration of gravity?
A larger planet has a stronger gravitational force.
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.
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.
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.
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 has stronger or weaker gravity than earth?
All of them do. There's no planet where the gravity is the same as on Earth.
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
How does Jupiter swallow in planets?
because of jupiter's gravity Bigger the planet stronger the gravity
Does a larger planet have greater or less acceleration of gravity?
A larger planet has a stronger gravitational force.
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.
Why is gravity in some planets more some not?
Gravity is stronger on some planets because the planet's core is much more dense. Making it's gravitational pull stronger. Which is making gravity stronger. that is sortof true
Does ceres the dwarf planet have weaker or stronger gravity than earth?
weaker
Is a planet with stronger gravity more or less likely to have an atmosphere?
More likely.
