Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
The moon orbits our Earth. The opposite would never be true; the Earth would never orbit the moon. One reason is due to the force of gravity. The object ____ has a greater gravitational force and that determines what satellites orbit around it.
A
with the greater mass
B
containing mostly water
C
with a thicker atmosphere
D
with the greater diameter
Explanation: 

Detailed explanation-1: -The moon revolves around the earth in a similar way but due to the velocity with which the moon got hooked onto the earth’s gravity keeps it from falling onto the earth. This keeps the moon in a pretentious orbit around the earth even though it is moving further away from our planet by an ever so little margin.

Detailed explanation-2: -The greater an object’s mass, the more gravitational force it exerts. So, to begin answering your question, Earth has a greater gravitational pull than the moon simply because the Earth is more massive.

Detailed explanation-3: -The mass of the Moon is less than that of the Earth.

Detailed explanation-4: -However, the reason the Moon stays in orbit is precisely because of gravity–a universal force that attracts objects. With the right combination of speed and gravity, satellites can fall around, instead of into, the body that they orbit.
