Its mass.
More mass=more gravity
Also the distance from the planet's center
to its surface, i.e. its radius.

What effects does gravity have on planets orbit?
Gravity, together with the planet's total kinetic and potential energy, completely determines the size and shape of the orbit.
What determines your weight on a planet?
Both it's mass and the force of gravity acting on it
What is the gravity on the planet Io?
Io is a moon of Jupiter, not a planet. Surface gravity is about 18% of the gravity on Earth.
How much more is gravity on the moon than the earth?
The moon has gravity but the earth has more because living people live in the planet.
What happens to the gravity on large and small planet?
Gravity depends largely on mass, the bigger the planet the greater the gravity should be
What determines gravity pull on a planet?
The force of gravity is determined by the masses of the objects and their distance apart.
What determine how much gravity something has?
An object's mass determines how much gravity it has.
What effects does gravity have on planets orbit?
Gravity, together with the planet's total kinetic and potential energy, completely determines the size and shape of the orbit.
What determines the pull of gravity at a planets surface?
It's mainly to do with the mass of the planet, the more mass, the higher the gravitational pull of the planet. The two are related.
How much gravity does planet venus have?
It has about 9/10 of earths gravity.
What determines your weight on a planet?
Both it's mass and the force of gravity acting on it
What determines how strong the force of gravity is at the surface of each planet?
The weight of an object on the surface of a planet depends on ...-- The mass of the object.-- The mass of the planet.-- The distance between the center of the object and the centerof the planet, i.e. the planet's radius.
Does the mass of the planet depend on how much gravity it has?
No. It is the other way around; gravity depends on mass.
Does planet Mars have gravity?
Yes it does but not as much as earth does. Every object that has mass also has gravity.
What property of a planet determines if the planet can have an atmosphere?
The mass of the planet. It's not clear cut, since there has to be gas around in the area to provide the atmosphere, but the planet (or moon) need to be massive enough to provide sufficient gravity for the gas molecules not to escape into space.
What came first the planet or it's gravity?
The particles of rock and dust that the Earth much later would be made from had gravity. Much, much, much later, the planet was formed. Every object that has mass also has gravititational attraction, even your body. Even a sewing needle has gravity.
Is mercurys gravity stronger than earths?
Planet Mercury and Planet Earth are both rocky planets. But Mercury is much smaller than Earth, so has much less force of gravity. Your answer is "No".
