It may sound like a lot of fun to lose a little weight every time the moon passes over you, but bear in mind tides. Gravity's pull weakens with distance. The distant side of the Earth, for example, now feels less gravity from the Moon than the side facing it. As a result, the far side of the Earth weighs more than the near side. This effect is called "gravitational self-weight". It's what causes objects to sink to the bottom of a lake or ocean, for example. Without this force, there would be no reason for ships to float or fish to swim upward toward the surface of the water. Gravity also decreases as you get farther away from a massive body (such as the Sun). Because of this, any object in orbit around another body will eventually fall back to Earth due to gravity's own effects. The Moon's influence on the Earth's oceans is what makes gravity decrease as an object gets farther away. If the Moon were not present, then gravity would remain constant regardless of distance. This means that any object in lunar orbit would never fall back to Earth because there would be nowhere for it to go. Of course, we don't want anything in lunar orbit because that would be very dangerous. If a rocket crashed into the Moon, for example, its fuel might cause global warming or pollute the environment.
