Question on the Oort cloud.

As a bit of testing for myself, I've had a look at whats called the evolution cruncher.. Basically its a pretty large list of misinformation, straw mans and just plain lies.So I'm slowly working my way through it, knowing that a lot of the questions asked by new creationists will probably come from this "cruncher".
And I come upon the question about the oort cloud..
So I've been looking over the internet about the oort cloud but I can't really find any solid information..Theres little bits of data here and there, can anyone point me to a book or article that seems to have more precise and conclusive data on it.. Most pages I visit give a lot of "we aren't really sure, but it might indicate or might prove" without any backing real information.Can anyone help me out with this one ?

Ahhh, didn't see that, thank you for that link, I shall ask my question there ^^
