Its not so much density that would give an object a higher gravitational pull, but overall mass.
Take the sun as an example, its overall mass is 99.85% of the total solar systems mass and with that has a huge gravitational pull, keeping all of the planets and other objects in orbit around it. At the surface, the pull is around 28g, 28 times that of earths surface gravity.
The average density of the sun is only around 1.4 g/cm3 though, compared with Earths average density of around 5.5 g/cm3, since the sun is mainly made from hydrogen and helium, while the earth contains a high percentage of iron, nickel and other dense elements.
The sun clearly has a higher gravitational pull though, its not really the density, but the shear amount of mass that determines the gravitational pull (earths mass is only about 0.0003% of the total solar systems mass.)

Does moon europa have gravity?
Yes. Everything has gravity. Larger and denser objects have more gravity than smaller objects that are less dense.
What determines how much gravity on a planet has?
Its mass. More mass=more gravity Also the distance from the planet's center to its surface, i.e. its radius.
Which planets have the largest accelerations of gravity?
The planet that has the largest acceleration of gravity is Jupiter. The planet with the least amount of gravity is Mercury. Actually, Pluto has less gravity than Mercury, but Pluto is not classified as a planet any more.
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.
Do larger planets have more gravity?
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.
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.
How would your weight change on the surface of an earth sized planet whose mass was greater the earths Why.?
Your weight is directly proportional to the mass and gravity of the planet, if the planet has a greater gravity and mass, you will weigh more.
Does gravity depend on the planet you are on?
YES! The bigger or more dense the planet is, the higher the force of gravity.
What conclusion you make about the mass and gravity of planet?
more mass = more gravity
Does moon europa have gravity?
Yes. Everything has gravity. Larger and denser objects have more gravity than smaller objects that are less dense.
How would your weight change on the surface of an earth sized planet whose mass was greater than earth why?
Your weight is directly proportional to the mass and gravity of the planet, if the planet has a greater gravity and mass, you will weigh more.
Can planet grow without gravity?
Gravity comes with mass so since a planet has mass there is some gravity. the bigger the planet the more mass it has. smaller planets have less gravity. so either way there is always some gravity on a planet.
How would jupiters gravity compare to that of venus?
Jupiter is more massive then Venus, so Jupiter has more gravity. (the more massive a planet is, the more gravitational force it has on other objects)
Does the earth have more gravity than mercury?
Yes, the bigger the planet the more gravity.
Is gasoline more denser than seawater?
Nope; specific gravity is lower
What determines how much gravity on a planet has?
Its mass. More mass=more gravity Also the distance from the planet's center to its surface, i.e. its radius.
What role does gravity play in the shapes of planets?
the bigger the planet the more gravity.the smaller the planet the least gravity
