The moon is slowly drifting away from us.
Every year, the moon gets just a little bit farther away from Earth — 3.78 centimeters, to be precise. This is caused by the interaction between its gravity and our oceans, which influence each other in such a way that a small amount of energy is transferred to the moon’s orbital rotation. Over time, those centimeters really add up: The moon is thought to have been thousands of miles closer to us when it was first formed approximately 4.5 billion years ago.
