I wonder how often perpendicular to the ground impacts occur? I seems that they could only occur if an asteroid approached in a head on collision with our orbit or perpendicular from a higher or lower orbit as it passes or is passed by the earth. That makes it statistically unlikely, doesn't it?
- chongli 3y agoThe statistical likelihood depends entirely on the timeframe. Within our lifetimes? Extremely unlikely for any large impact. Over the next billion years? A lot more likely!

- golemotron 3y agoNope. I was referring the likelihood of perpendicular collisions out of the set of all possible collisions. No time dimension.
