The distance between a planet and an object affects the gravitational force between them. That means the size of a planet affects the value of the "surface gravity" for that planet. The greater thedistance from the surface to the center of the planet, the smaller the gravity at the surface (for the same planet mass).
An example is the fact that Mars and Mercury have almost exactly the same
surface gravity. Mars has more mass than Mercury, but this is balancedby the fact that Mercury hasthe smaller radius.

What is gravity and how does it affect planets and the oceans?
gravity is something that can affect the planets.
What are the planets that affect gravity?
every planet
Why is why is there gravity on some planets but not on others?
There is gravity on all planets. The strength of that gravity varies depending on the size and mass of each planet.
How does gravity affect the galaxy?
Gravity holds everything together in the galaxy. (planets)
Does gravity affect your weight on different planets?
yes it does
Does earth have strong or weak gravity?
Because of Earth's size, and considering it as one of the smallest planets, it has a weak gravity compared to the OTHER planets. Most planets have greater gravity because of their size. Earth has a stronger gravity compared to mars, mercury, and venus.
How does the size of a rugby player affect gravity?
The size of a rugby player does not affect gravity in any way.
What affect does gravity have on the planets?
The planets' own gravity has made them spherical. Also there are other effects such as their ability to retain an atmosphere, etc. The Sun's gravitycauses the orbits of the planets.
How does Earth's gravity affect the planets?
The effect is very small.
Is it true that the closer the planets are to the sun then the less gravity the planets have?
No. The surface gravity of a planet depends on its size and mass, not its distance from the sun.
Does size affect gravity's strength?
Size does not but mass does.
How is the planets size related to the pull of its gravity?
The larger the mass of the planet, the greater the force of its gravity.
