more mass = more gravity
The larger the planet mass, the bigger force of gravity it has.
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.
Where there is mass there is gravity.
No that is impossible. Gravity is related to mass, so while a planet still has mass it still has gravity.
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.
Its mass
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.
A planet gets its force of gravity from its mass and the distance from its center. The more massive the planet, the stronger its gravitational pull will be. Gravity is a fundamental force of nature that attracts all objects with mass towards each other.
Objects have a gravitational pull proportional to their mass.
Linearily.
No. The strength of gravity on a planet depends on its size and mass.
Its mass. More mass=more gravity Also the distance from the planet's center to its surface, i.e. its radius.
