Every year the moon moves 3.8cm away from the Earth, this is caused due to the tidal effects, and consequently Earth is slowing in rotation by about 0.002 seconds per century.
There’s a theory that scientists discovered which suggests that the moon was created over 4.6 billion years ago by an object the size of Mars.
You can buy parts of the moon, how cool is that! I don’t really know who the money would go to though, because nobody really owns the moon do they? I know that was kind of, off topic, but its still cool.
