Reddit mentions of What If the Earth Had Two Moons?

There is a book that explores this and other strange hypothetically not impossible ways to arrange earth-like planets https://www.amazon.com/What-Earth-Had-Two-Moons/dp/B0085SJYRE

It’s really great and covers so much stuff.

Worth the cash, very cool book.

You should definitely read What if the Moon Didn't Exist? and What if the Earth Had Two Moons? by Neil F. Comins. I haven't looked for the first one yet and, uh, only got a few chapters into the second book because it got a bit jargon-y in places and I had a lot going on at the time, but it was really interesting. He included a little short story before each chapter about how a famous event in history might have played out in the different world, and he goes into lots of detail about how the different day/night cycles would affect biological clocks and stuff. Very cool! I'll have to actually finish it sometimes.

Try this book: "What If the Earth Had Two Moons?". It's one of those what-if type books that revolves around how Earthlike planets in non-Earthlike situations would be possible and what life would be like. I actually generally recommend it for scifi stuff - it's very interesting and indepth. You want an Earthlike planet with a thicker crust? Well according to this book, the crust would periodically melt, and life would have evolved to know when the crust is thinning and thus when to run like fuck away from that area of the continent.
