How would the Earth be effected if it had more than one Moon?

Answer 1

The moon is a hughe mass. It attracts everything on the earth, less than the sun that is millions times bigger (even if farther) but still...

You don't notice it but you are lighter when the moon is just over you head and heavier if it is at the opposite side of earth.

The most visible effect is the tide. But everything is attracted, the atmosphere, and even the ground.

So to answer correctly your question, you may consider:
* how many more moons,
* how big are they (consider their mass),
* how far from the earth,
* are they spinning at the same speed....

It might be catastrophic !!!

Answer 2

too many ways to interpret this. At face value - if the earth did have a second satellite of exactly the same dimensions, mass, and orbit of the 'moon' , and if it was exactly opposite to the position of the current moon - two things - the tidal forces on the Earth would result in 70 foot tides where 7 would now be the norm. And by the way - the increased gravitational influence would play hob with the Earth's internal makeup - continents drifting, volcanism, just little things ya know. IF the earth had two similar sized moons we (hey, include life in general, from microbes to dinosaurs) would NEVER exist - the ball we live on would be an unstable seething mass of rock, with no atmosphere. Earth is unique in having an association with a relatively large body of (relatively) no mass commensurate with its size. In place of the Moon, a stable system of smaller satellites might exist - but that is physically unlikely to have left the Earth unscarred. So - our large captured satellite, the 'Moon' is likely unique in a local planetary configuration.
To sum up - two 'moons' to start with, no life would have developed, Earth would need far more mass to avoid tidal force on the crust (6 to 8 X I figure). Extra moon shows up - during gravitational capture IF it did not hit our moon - well - you're dead anyway.

Answer 3

It would cause massive floods and winds... same as if our moon were any closer than it is now... based upon what is called the inverse square law... the gravitational pull the moon has on Earth, would exponentially increase causing disaster.

Answer 4

The tides would be different. It can affect the height of organisms.
Moreover there will be another Neil Armtrong and Moon II Missions

Answer 5

Tides, and depending on the speed of revolution and rotation, possibly a shadow. Our Moon always comes at night, the new one might come at day, provide an eclipse of the sun more often than our current one if it comes at day.

Answer 6

than we could have had plans to pollute more moons by bringing humans to it by private flights and make the already rich people more rich and then we would have had a space war with usa sayin no this is our territroy and russia sayin ok but the other one is ours and iran sayin ok well 3rd one is ours then usa would find oil in iran's moon and bomb it. and then the moon since its made of cheese would get destroyed and big pieces of cheese will fall on earth and then cheese would be free for all and even the skinny people would get fat and fat people would get more fat and then we would all die from heart diseases...
wow! i have got imagination

Answer 7

the tides would be different. there would possibly be more quakes. more full moons(not human of course!). the cliche once in a blue moon would be a figment of the imagination!

Answer 8

Depending on how close the moons were to each other it might cause flooding.

Answer 9

Depends the size, and orbit direction of the other moon...

Answer 10

In a month there were 4 full moons and 4 new moons..... hehehe!!!!!!!!!!!
