    By far the coolest and most unique aspect of the Earth-Lunar system is solar eclipses. The size and orbital distance is just right to allow for the spectacle we get today.

    This is even more true when you consider that the Moon’s average orbital radius is increasing by 3" (76mm) each year. In a million years, the Moon will be too far away to fully cover the Sun. A few million years ago it was close enough to fully cover the corona

      Honestly, whenever I think about this, I get my tinfoil hat moment. Life being created by statistical probability and chance, well ok. Life being created and people with conscientiousness rising up at exactly the time this one planet has this perfect orbital distance - give me that tinfoil.

        That’s just our bias talking. There’s certainly many other wonderful events we missed by a couple million years. We just think the moon size is special because of this coincidence.

        Earth’s orbital distance has pretty much always been “perfect” though. It hasn’t really changed much since it’s formation 4-5 billion years ago.

        Unless you mistyped and you’re talking about the moon’s orbital distance? In which case, it’s actually kind of the opposite of what you’re claiming. It’s estimated that life first popped up pretty close to when the planet and moon finished forming, at which point the moon’s orbital distance would have made it appear larger than the sun and probably fully obscure the sun + it’s corona during an eclipse.
