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.)

Why weight would be different on planets by talking about gravity?
Weight is the force of gravity acting on an object's mass. Because gravity varies from planet to planet, an object would weigh different amounts depending on the gravitational pull of that planet. For example, an object would weigh more on a planet with stronger gravity, like Jupiter, and less on a planet with weaker gravity, like Mars.
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.
Does moon europa have gravity?
Yes. Everything has gravity. Larger and denser objects have more gravity than smaller objects that are less dense.
Astronauts weight the same as they would on other planets?
Astronauts' weight would vary on different planets due to differences in gravity. Their weight is determined by the gravitational pull of the planet they are on, so they would weigh less on a planet with weaker gravity and more on a planet with stronger gravity.
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.

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, gravity does depend on the planet you are on. The force of gravity is determined by the mass of the planet and your distance from its center. Therefore, gravity will be different on each planet based on these factors.
What conclusion you make about the mass and gravity of planet?
more mass = more gravity

Would a smaller planet than earth with the same shape and size have more gravity?
No, the gravitational force experienced on the surface of a planet is determined by both its mass and radius. A smaller planet with the same shape and size as Earth would have less mass, which would result in weaker gravity compared to Earth.
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.
Astronauts weight the same as they would on other planets?
Astronauts' weight would vary on different planets due to differences in gravity. Their weight is determined by the gravitational pull of the planet they are on, so they would weigh less on a planet with weaker gravity and more on a planet with stronger gravity.
Does the earth have more gravity than mercury?
Yes, the bigger the planet the more gravity.
