Our moon holds so many mysteries. Just the very fact that such a large object can be so close in proximity to us while also orbiting is mind boggling.

But the really fun part is described in the link above:
> Tidal interactions cause the Moon to spiral about one inch per year away from Earth. In the distant past, the Moon was close enough to Earth so that it could block the Sun's entire disk and then some. Our prehuman ancestors would not have witnessed the beautiful coronal displays that we now enjoy. And about 50 million years from now, the Moon will be far enough away so that our descendants will only see annular eclipses.
factoid
făk′toid

2. A brief, somewhat interesting fact.
3. An inaccurate statement or statistic believed to be true because of broad repetition, especially if cited in the media.
I assume the definition used here is #2. I’m actually surprised by 1 and 3. I have never heard it used in that context and it’s strange that one word would have 2 fairly contradictory interpretations.
