One Day You'll Only Be Able To See The Moon From One Place On Earth

Whether you're in Australia, Belize, or Canada, you're eventually going to see the moon in the night sky. And that just makes sense—the moon orbits the Earth, so of course it will cross the night skies of every hemisphere. But actually, it doesn't have to happen that way. The Earth is spinning in addition to being orbited by the moon, so there's no reason why the moon's orbit wouldn't just lock in with one particular side of the planet and always be visible overhead from there. Because of how gravity works, that's eventually exactly what's going to happen. Watch the videos below for more.

Key Facts In This Video

  1. Tidal forces cause high tides twice a day: once when the moon is overhead, and once when it's on the other side of the Earth. 00:20

  2. Eventually, the Earth will spin slowly enough that the same side will always face the moon. 01:06

  3. If the moon was too close to Earth, tidal forces from the Earth would cause the moon to disintegrate. 01:21
