If the Earth had multiple moons (let's say 10) all equally visible to us and about the same size as our current moon, what effect if any, would that have on our planet?
What to do think about the previous? (Probably disaster. At least a state of constant tremor. More likely constant earthquakes, volcanoes, and tsunamis. One moon stirs the oceans and moans the crust plenty now. ) Do you think that theory can be possible?The answer depends upon the orbits of the moons, not just the moons themselves.
The dramtic tidal effects on Io may explain this to you. Jupiter pulls on Io which causes the crust to crack. It works like our oceans with water but with rock. A Syzygy with many moons would cause the tides to rise quite a but in some areas.Jupiter has 79 moons, so perhaps 1 is strange. There is also no data supporting that earthquakes which cause tsunamis are caused by the lunar phase, and vulcanism is a release of pressure in the Earth as well not lunar in any means.
More moons might also create more stability as the pull of ones gravity could depending upon orbit could actually offset the pull of another moons gravity. On the other hand if these moons orbited together on opposite sides of the Earth the tidal flux would be tremendous exposing ocean bottoms never seen now and covering many mountains, as such land life would be far more difficult if even possible.
It was a dramatic example to explain it to you.Jupiter to Io is not 11 moons the size of ours to Earth
Math works.
Better for some than others.
