What would it take to have the moon crash into Earth?

it is interesting you should ask that.....just the other day a few friends and I got together and talked about that....here's what we thought.

there is a comet coming towards earth.....it is supposed to come really close to earth but not hit us......what we thought might happen if the comet passed threw the space between the earth and the moon it JUST might cause the moon to shift its gravity towards the earth.. and that MAY cause the moon to crash into the earth witch MAY destroy the earth or at least throw it off its axes.

but hay, it was a bunch of people that got together and just talked about stuff like that... I find that fun..

have a great conversation about that with some of your friends.

The moon is actually currently going AWAY from the Earth. It would take a very big asteroid to hit the moon to move it even a little. Maybe then, it would be near enough to be attracted faster into the Earth. But small space rocks will just poke the Moon and it will not do anything serious.

Usually, earth satellites slowly (very slowly) fall nearer and nearer toward the Earth.

You asked interior the Astronomy & area classification so the respond is none. There are no astronomical circumstances of the moon falling into the Earth. How might desire to there be, whilst the moon is actual receding from the Earth on the cost of roughly 4 cm consistent with year. Your examples are of video games and works of fiction, so which you will possibly be able to get diverse solutions in case you ask in Gaming or entertainment or Literature.

Technically, the moon is always falling towards the center of the Earth, it's just got enough tangential velocity to keep it falling in a nice elliptical path.

You could just eliminate the tangential part of the velocity (it's moving mighty fast around the earth (Pi*475,000 miles) / 28 days = 53,000 miles per day = approx. 2000 miles / hour.)

That'd take a mighty big rocket...

No gravitational force needed...

U need only two thigs-

1) Huge amount of money for buying a Huuuuuuge rocket propulsion Unit

2) Even bigger Jackass to fit that on moon

It doesn't need moon crash to bring us to doom's day, just an asteroid with 300- 400 meter width is enough to zip a country (http://archives.cnn.com/2002/TECH/space/01/07/kill...

The moon diameter according to wikipedia is 3,476 kilometers.

10,000 times bigger than above mentioned asteroid.

Of course the speed it hit us is also a big factor in how much damage will result.

Anyway we won't feel anything when it happened especially when we are asleep.

Wouldn't the sun have to be eliminated? Isn't the Earth's gravitation pull being contradicted by the Sun's? I don't know. Just guessing. ;)

i guess if no form of gravity existed in space, to hold the bodies in place, the the moon WILL crash into the earth

without the moon, there would be no gravitational force.

Some really, really bad luck.
