It's big, it would do much damage if it hits, but no planet killer. The one that hit chixaclub was about 6 miles wide, this one about 1/12 the size. Explosive yield equal too about 10 Gigatons creating a crated 4 miles across and about a half mile deep. So, I'd want to be a survivor. It would be bad, but not on order of the one that 86ed the dinosaurs.
