Question

Quizplus · Accepted Answer

The Moon does not crash into Earth because it has a sufficient tangential speed, meaning it is moving fast enough sideways to not fall into Earth's gravitational pull. Earth's gravitational field is strong enough to keep the Moon in orbit, but the Moon's tangential speed keeps it in a stable orbit instead of crashing into Earth. The gravitational pull of other planets is not a significant factor in keeping the Moon in orbit around Earth. The mass of the Moon compared to Earth also plays a role in the stability of the system, but it is not the main reason that the Moon does not crash into Earth.
