Well educate me on how I wasn't right then.

My take on this is if the Moon felt the Suns gravity more than the Earths then it would soon be ripped away (This is the upper Roche limit if I'm correct)

So since it's in a stable orbit around the Earth, then it feels the Earths gravity the most.

Cruithne on the other hand isn't in a stable orbit around the Earth. The Sun has the greater gravitational influence on it.

I was merely pointing out these differences.

But the moon and Cruithne are different. Obviously the moons is mostly effected by the Earth's gravity, whereas Cruithne is mostly effected by the Sun's gravity.

Actually do you have any articles on those proofs? I've had plenty of arguments on this, and I can never think of anything that proves that the speed of light is constant.

Another interesting question: let's forget another moon, but let's move our present moon nearer the Earth. How near it would come that it's orbit would be stable and it would not yet disturb Earth's revolving around the Sun. If the size of our Moon would be smaller, it's minimum distance could of course be smaller.

Can't you just use Newton for this? (to a good approximation)

Just work out at what point the moons gravity is larger than the suns gravity and you have the point of perturbation.

I know it's rough, but its a start and it doesn't have you dealing with the three body problem

you mean theres no way the gravitational pull of earth can stablize the satellite?

First post here, but I think I have the hang of this whole science thing

There are five points in space (at least that I can remember) where the gravitational pull of earth and moon cancel each other out. So at these points, yes the earths gravitational pull will correct for it.

Anywhere else though, no you need rockets to correct for this.
