ANSWER
The earth
Step-by-step explanation
We want to know the celestial body that exerts a greater force on the other.
The gravitational force is a non-contact force of attraction is a force that acts between any two bodies that have mass. This means that once two objects have mass, they are attracted to one another by the force of gravity.
Because the force of gravity is a force that depends on the mass of the objects, a body with greater mass can exert a greater force of gravity on another body.
This implies that the greater the mass of the body, the greater the force it exerts on the other body.
Hence, the earth exerts a greater force.
