Why do we only ever see one side of the moon? The moon completes one rotation around its own axis in the same amount of time it orbits earth. The two are perfectly in sync! But it wasn’t always that way... When the moon formed, likely from a collision with earth, it was a hot molten object spinning wildly, changing shape, pulled by Earth’s gravity. As it settled into its orbit, Earth’s gravity pulled on its closer edge, making it into an oval shape. This created an uneven pull as it rotated on its axis. Over time this constant tug on the Moon’s bulge… caused its rotation to slow, and eventually match Earth’s… This is “tidal locking,” an effect that’s actually quite common and found in most large moons in our solar system. Because of this, humanity didn’t see the back of our own moon until 1959. And turns out it looks COMPLETELY different!

00:00Why do we only ever see one side of the moon?
00:03It is weird.
00:04The moon completes one rotation around its own axis
00:07in the same amount of time that it takes to orbit the Earth.
00:09The two are perfectly in sync.
00:11But it wasn't always that way.
00:13When the moon formed, likely from a collision with Earth,
00:15the hot, molten, messy object was changing shape,
00:18pulled by Earth's gravity.
00:19And as it settled into its orbit,
00:21Earth's gravity pulled on its lower edge,
00:23making it an oval shape.
00:25And over time, this constant tug on the moon's bulge
00:28caused its rotation to slow,
00:30and eventually to match Earth's.
00:33This is tidal locking,
00:34an effect that's actually really common
00:36and found in most large moons in our solar system.
00:38Because of it,
00:39humanity didn't see the back of our own moon until 1959.
00:43And turns out, it looks completely different.
