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.
every planet
There is gravity on all planets. The strength of that gravity varies depending on the size and mass of each planet.
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.
The size of a rugby player does not affect gravity in any way.
The effect is very small.
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.
No. The surface gravity of a planet depends on its size and mass, not its distance from the sun.
Size does not but mass does.
The larger the mass of the planet, the greater the force of its gravity.
Yes, gravity affects your weight on different planets. Weight is a measure of the gravitational force acting on an object, so on planets with stronger gravity, you would weigh more, and on planets with weaker gravity, you would weigh less compared to your weight on Earth.
Two factors that affect a planets revolution are distance from the sun and size.
You know that no planets actually orbit the earth right? ...?
