I'm working on building a fantasy world where the moon is in a lower orbit. I've already worked out the effect on tides; 4x stronger high tides slightly further apart, increased coastal erosion, more coastal towns like Le Mont St Michel isolated at high tide. I've also calculated that the orbital period of the moon would be 9.64 days meaning shorter "months". But I'm struggling to work out how regularly eclipses would occur and how they would be different.
If the moon was closer, the Earth's wobble would decrease, would this along with the increased size of the moon in comparison to the Earth and Sun mean there is a lunar eclipse every full moon and a solar eclipse every new moon?
I believe a total lunar eclipse would leave a ring of the moon visible around the shadow of the earth and a solar eclipse would be complete darkness with no corona visible, is this correct? How long would each last?
