    $\begingroup$ You beat me to answering, and with a better answer than mine was going to be. One question though: Since the moon is the same size but the umbra of the earth is larger at the moon's new distance, doesn't that mean total lunar eclipses will occur more often? $\endgroup$

  • $\begingroup$ The diagram is exaggerated, those lines are very close to parallel. The moon currently can fit entirely between the umbra and penumbra, but make the moon bigger and its an extremely tight fit. I'll add a diagram. $\endgroup$

    $\begingroup$ The moon in this question isn't bigger, it's just closer to earth. That means it will fit in the umbra more easily. $\endgroup$

    $\begingroup$ I agree, the moon will appear bigger to an observer on earth, and this will have a significant impact on solar eclipses. However, length of a lunar eclipse is dependent on the opposite: How big does the earth appear to someone on the moon? The bigger earth appears, the bigger earth's umbra at that distance. It may only be different by a small amount due to the difference in earth/moon distance vs earth/sun distance, but the umbra will still be slightly bigger. Combine this with the moon's newly increased speed and you should be getting total lunar eclipses more often than before. $\endgroup$

    $\begingroup$ Sadly, noone will see these megaeclipses, as the closer moon would not have allowed life in the way we know it - tides would also be much more rampant... $\endgroup$
