We do not. An object will fall toward the center of gravity only if it begins at rest. Asteroids do not begin at rest; they are already in motion. That's why they don't fall straight down
I'm not sure what the phrase is for the logical fallacy you're employing, but it's there. It also took me a bit to figure out where you were finding an extra 4700 kilometers, until I realized you were hung up on thinking that the barycentric center of gravity of the Earth-moon system is in any...
The idea is that the moon's gravity changes the trajectory of asteroids whose path would otherwise cause them to strike the Earth. But that works both ways: the moon's gravity is every bit as likely to change the trajectory of other objects which would have missed the Earth, curving them into a...
If I were given to fanciful interpretations of geological (Arelogical?) features, I'd be more interested in these "Nazca lines" about 1.5 km to the southwest:
