Moon closer?

There’s a new film out about the Moon getting a lot closer to the Earth. Its by the same director as ‘Independence day’ and ‘the day after tomorrow’ I think?

There is also a video on Instagram showing the Moon closer and instead of being tidaly locked with the Earth (one face always towards us), it’s shown wobbling irregularly.

Thinking about it I wondered what would happen. Unless it was hit by something very large it wouldn’t move closer to us. But if it did I think we would have massive tides and earthquakes. The land rises as the moon passes over it. The question is how close does the video or film represent? The closer, the worse the effects. I know the moon is slowly moving away by a few centimeters a year, its been measured with a laser fired at mirrors left on its surface by the Apollo missions. If it was knocked away the Earth’s tilt would become worse and our spin unstable. Either way not good news…
