[He Rides A White Horse]

There was an asteroid labelled 2009 DD45 that passed by earth approximately 45,000 miles away. That is close even for the moon which is a mean distance of some 250,000 from earth.

I don't think the size difference is what matters. I would guess that when you take into account the vast distances in the cosmos and the solar system, it is probably the same chance.

I might say that if you played a lottery with a billion to one odds, buying four tickets would not increase your winning potential four-fold.

Yes it would. Learn some math.

Good point. The difference in the odds is so infinitesimally small as to be unworthy of note.
