The answer is gravitational attraction. It is the attractive force between all objects that have mass. It's between you and me, you and your PC, and between everything.
Gravity
gravitational attraction.
Considering the mass of the two objects should answer that question.
A natural force of attraction exerted by the Earth upon objects that pulls the objects towards Earth's center
It's the mutual forces of gravitational attraction between the Earth and each object.

gravitational attraction.
The gravitational forces of attraction between two objects is greater when the product of their two masses is greater. That's why a person with greater mass weighs more when he stands on the Earth's surface.

Any two objects with mass will have a gravitational force. The orbit of planets around stars depends on the gravitational pull of the star. The Earth exerts a gravitational pull on its moon but the moon also exerts a pull on the Earth.
Yes, tides are caused by the gravitational attraction that the moon exerts on the Earth and its bodies of water.
It's the mutual forces of gravitational attraction between the Earth and each object.
