You're asking about the force of gravity between an object and the Earth. Here's the breakdown:

The force of gravity depends on two things:

1. Mass of the object: The more massive an object, the stronger its gravitational pull.

2. Distance from the Earth's center: The closer an object is to the Earth's center, the stronger the gravitational pull.

Since we're talking about the Earth's surface, the distance is the same for all objects. This means the object with the greatest mass will experience the greatest force of gravity.

Therefore, the object with the greatest mass will have the greatest force of gravity to the Earth at its surface.

Let me know if you'd like to compare the forces of gravity between specific objects!
