Cuz it's far away and big and thus appears to be moving with you, rather than away from you.
This is also true if you're driving on a highway and look to your left through the window and see a distant ridge with some trees on its lip poking
into the sky. They appear to be moving slowly while the trees nearby seem to whip by. I'm not versed in all of the math, but an object that's real
close and you pass it by within a time span of 0.5 seconds, will have crossed a greater anglular motion than an object far away, even if it's
equivalent in every way except distance.
I would think photographers or 3d-game programmers would get it immediately since they're familiar with thinking in terms of angles and math because
they use them so mcuh in their work.
I am thinking of those projectors they use in classes or during talks.
As a matter of fact, the other day I was walking to the store and thought about how we can see shadows and rays of light through trees and how we can
see our reflection in water. I was thinking about how people hundreds of years ago must have thought about light? Did they think it was a substance or
an energy? Well, they must have seen shadows and rays of light and reflections, so they knew that light somehow must travel from point A to point B
and/or be obstructed by something in-between. And yet you can't touch light like you can touch a rock or a tree, neither does it make noise. They
couldn't store it in buckets like with water. A fun intellectual exercise.
