The gravity of a planet is directly proportional to its mass, and inversely proportional to the square of the distance from the center of mass. For the gravity on the surface of the planet, the distance is just the planet's radius.
Thus, if a planet has three times the mass, it has three times the gravity. If you are three times as far away, the gravity decreases by a factor of nine.
What else can I help you with?
Why do all the planets have different fields of gravity?
Planets have different fields of gravity because their mass and size vary. The larger and more massive a planet is, the stronger its gravitational pull will be. The strength of gravity on a planet is determined by its mass and radius.
How does the gravity of the planet vary with the planets mass?
The gravitational force on an object at a standard distance is proportional to the mass of the planet.
How does the planets mass vary with the gravity of the planet?
The gravitational force on an object at a standard distance is proportional to the mass of the 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.
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.
Why do all the planets have different fields of gravity?

Where do the planets get gravity?
Planets have gravity because they have mass.
How does the planets mass vary with the gravity of the planet?
The gravitational force on an object at a standard distance is proportional to the mass of the planet.
How does the gravity of planets vary with their mass?
The gravitational acceleration of a planet at a fixed distance from its centeris directly proportional to its mass.
How does gravity of the planets vary with their mass?
The gravitational acceleration of a planet at a fixed distance from its centeris directly proportional to its mass.
How does gravity of planets vary with their mass?
The gravitational acceleration of a planet at a fixed distance from its centeris directly proportional to its mass.
How does the gravity of the planet vary with the planets mass?
The gravitational force on an object at a standard distance is proportional to the mass of the planet.
How does the gravity vary with the planets mass?
The gravitational acceleration of a planet at a fixed distance from its centeris directly proportional to its mass.
Does this planet have gravity?
All mass produces a gravity field. All planets have mass. Therefore all planets have gravity.
Does the sun give planets gravity?
No. Planets have gravity as a result of their own mass.
What planets have large gravity?
Planets with a large amount of mass.
Where does the gravity that holds the planets in their orbits come from?
The gravity that keeps the planets in orbit is the sun's gravity, which is a product of the sun's mass.
