This one's actually true. Sometimes we don't find asteroids until after they've narrowly missed us.
What never made sense to me was how Nightfall passed between Earth and the Sun the way it did but was still on a collision course. The geometry just doesn't work. Maybe I'm not accounting properly for the Earth's gravitational pull on it, but it seems like the writers just didn't think it through. ::end rant::
