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.

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 do all the planets have different fields of gravity?
Gravity is a function of mass. All the planets have different mass, so different gravity.
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 the gravity of planet mercury vary with its mass?
Gravity is directly proportional to 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 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 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 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 vary with the planets mass?
The gravitational acceleration of a planet at a fixed distance from its centeris directly proportional to its 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.
Where do the planets get gravity?
Planets have gravity because they have mass.
Does this planet have gravity?
All mass produces a gravity field. All planets have mass. Therefore all planets have gravity.
Why do all the planets have different fields of gravity?
Gravity is a function of mass. All the planets have different mass, so different 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.
