Enjoy this great little video about an asteroid hit as viewed by a dinosaur on ancient Earth.  The one in the video is 10Km wide and it’s the size of the one that killed the dinosaurs at the end of the Cretaceous-Paleogene period 66 Million Years ago.  For reference, the Asteroid BL86 that passed by us this week was 300Km wide, a true killer! Sadly there’s no explosion, but hey, if we were able to see it we would be instantly vapourized so we wouldn’t be watching it anyway.
