How did the Moon end up with an orbit the perfect distance to cause total eclipses?
In: 1369
It’s a complete coincidence. The moon’s original orbit was much closer to the Earth, and it has been moving ever so slowly further away ever since. Eventually, the moon will be too far away for total eclipses to happen at all. So, it’s not so much that the moon’s orbit just happened to work for eclipses, but rather that we happened to be alive at the right part of the moon’s life to be here to see them (although earlier in time, they all woulda been total).
