LOL, please, you infer something is wrong with a source rather than show it. Nice.

www.lpi.usra.edu... is that affiliated with NASA?
I don't have to give you the odds of the earh capturing anything. The moon( or your fantasy, errr I mean craft) was formed from a process of aggregation from impact of both the impactor, surrounding debris and the earth. Are you unaware of the masses of materials that are observed floating through the universe. Are you unaware of comets and meteors, asteroids and such. Can you not agree that this is a possible cause of the moon?
Can you give me the odds of an object the size of our Craft..err Moon ... finding itself 'captured' by our planet - over say our Suns pull?
LOL. Sure. Spare me the act.
I'm pretty uneducated, as you can tell - never passed an exam to get into the field of Astronomy...
No, I could not say that. But can you please show me where you know all there is to know about your fanta...err craft.
So you could also say us Earth dwellers know all about the Craft...err Moon (sorry - dunno why I keep doing that!) and that's that?
Or would you say there are still a few oddities that can't be explained on our Craft ...Moon (old habits you know) such as "classified" things and the such - I mean you sound like you know it all - I am all for learning something *new*
Wrong-Leonard, on page 195-196 in SEOM took it from ISAAC ASIMOV, not ASMOVIV. Asimov wrote the the quote below in his works Asimov on Astronomy. He wrote this as a group of short essays. Asimov was a brilliant writer of sceince fiction. He was a biochemist, brilliant writer, but somehow I think you know that.
Taken from George H. Leonard - Somebody Else Is On The Moon, 1976.
What Asimov is talking about here is Issac Newtons garvitational attraction equation. With this you can work out a field where satelites(like your craft) sit in relation to the gravitational pull between the Sun and the Planet that the satelite Orbits..
"Isaac Asmoviv says there are nine moons in our solar system that have been captured: one of Neptune, o...........iter, which has a ratio of 1.03. He calls the other satellites "true satellites."
Do you know what a true satelite is? Just because the moon sits outside of a definition of a true satelite does not mean it was put there by ET's. Did Asimov include all factors involved in determining orbits? No. He did not.
And then he comes to our Moon. It is important to quote him:
It is a shame that one small thing remains unaccounted for; one trifling thing I have ignored so far, but - WHAT IN BLAZES IS OUR MOON DOING WAY OUT THERE? It's too far out to be a true satellite of Earth, if we go by my beautiful chain of reasoning -
Asimov is challenging the conventional thoughts on the Moon as a captured body. Asimov is right not to abandon Newtonian physics, but by only presenting one possible reason for the moon, the theory that it was captured, is poor science.
which is too beautiful for me to abandon. It's too big to have been captured by the Earth. The chances of such a capture having been effected and the Moon then having taken up a nearly circular orbit about the Earth are too small to make such an eventuality credible.
See, how he challenges the reader to pose an answer. You insert Craft here, I insert impact, aggregation theory.
There are theories, of course, to the effect that the Moon was once much closer to the Earth (within my permitted limits for a true satellite) and then gradually moved away as a result of tidal action. Well, I have an objection to that. If the moon were a true satellite that originally had circled the Earth at a distance of, say, 20,000 miles, it would almost certainly be orbiting in the plane of Earth's equator and it isn't.
But, then, if the Moon is neither a true satellite of the Earth nor a captured one, what is it?...
Only from the perspective that it was a captured object- the ratio is towards the sun if we give the gravitaional influence of the Sun preferance, but it does not work that way.
he goes on to conclude the tug-of-war ratio for the Moon: 0.46. We would lose the tug of war with the sun. We - Earth - attract the Moon half as strongly as does the Sun.
It is actually Isaac Asimov. Asimov on Astronomy. He was a biochemist who wrote alot of stories. This book was one on popular science and his interpretations for a general audience.
