Here's what the Earth & Moon look like for a month from eachother This was reconstructed from real images, with night-side Earth made brighter / cloudless so you can see it. Jin can have the one on the right, thanks for sharing science #BTSarmy

Oh and you can add your own music to this and reshare as you please. I generally don't because of copyright fears... and to keep my videos as shareable as possible

FAQ: does the Moon rotate?

Yep! It takes 27.322 days for the Moon to rotate, which is *exactly* how long it takes the Moon to orbit Earth

So, we always see the same side of the Moon because it constantly rotates into our view as it orbits

But why *does* the Moon face us with one side?
The mechanism is called tidal locking, it happens (for example) on the 2 moons of Mars and all the large moons of Jupiter. It's very common!
(read on)

Earth deformed the Moon *very slightly* into an oval shape thanks to gravity pulling the Moon's near-side strongly and the far-side weakly. Before the Moon was locked, Earth's gravity slowed down the Moon's rotation constantly until it stopped (img https://commons.wikimedia.org/wiki/File:MoonTorque.jpg)

Earth's rotation has also been slowing down since pairing up with the Moon -- for example, a day used to be 18 hours long (1.4 billion years ago), and the days are still getting longer... about 0.0016 seconds longer every 100 years :-)

Well done for getting deep down the thread. Usually when I share an animation I make a few thread posts to capture most of the FAQs that I think will come, then later I add more posts to capture most of the remaining ones. So, there's a reason to hit follow, eh.

More info: the Moon is egg-shaped, with the large "pointy" end facing Earth

I should have said the egg butt.
