weight
The gravitational force exerted on an object is called weight. It is the force exerted by gravity on the object's mass.
gravitational mass
Gravitational force F = mass x g where g is the gravitational acceleration.
There is no minimum mass at which point an object (celestial or otherwise) begins to have a gravitational force. Any object with mass has an associated gravitational force. The magnitude of that force is proportional to to the mass of the object - lots of mass results in lots of gravitational force; little masses result in only little gravitational force.
The greater the mass, the greater the gravitational force.
The mass of an object does not change when the gravitational force changes. Mass is a measure of the amount of matter in an object and is independent of the gravitational force acting on it.
Gravitational force is the strongest when you are the closest to a mass.
More mass will cause more gravitational force.
You can increase the gravitational force between two objects by increasing the mass of at least one of the objects. Gravitational force is directly proportional to the mass of the objects involved, so the greater the mass, the stronger the gravitational force between them.
The strength of the gravitational force between two objects is directly proportional to the product of their masses. This means that the greater the mass of the objects, the greater the gravitational force between them.
The area where objects feel a gravitational force is called a gravitational field. This field is created by the presence of mass in space and determines the strength and direction of the force experienced by objects within it.
Your weight. Weight is the definition of the force between the earth and other objects. Thus you weight is the gravitational force acting on you from the earth.
