It's not about a specific distance where the Moon's gravity suddenly "turns off" and Earth's takes over. Gravity is a continuous force that weakens with distance, but it never truly disappears.

Here's what's really happening:

* Both Earth and the Moon exert gravitational pull on everything around them.

* The strength of gravity depends on the mass of the object and the distance from it. The more massive an object, the stronger its gravitational pull. The closer you are to an object, the stronger its pull.

Therefore, the gravitational influence of both Earth and the Moon is always present. As you get closer to Earth, Earth's gravitational pull becomes stronger, and the Moon's pull weakens.

The point where Earth's gravitational pull becomes stronger than the Moon's is called the "Lagrange Point L1". This point is located about 326,000 km (203,000 miles) from Earth, on the line between Earth and the Moon.

It's important to understand:

* There's no magical point where one force suddenly dominates. The transition is gradual.

* The Lagrange Point L1 is a point of equilibrium. At this point, the gravitational forces of Earth and the Moon balance each other out. This doesn't mean there's no gravity there, just that the two forces are equal.
