Because I was curious and had no idea about the relative size of meteors that hit the moon, the one that hit the moon in 2013 and was captured by Spanish astronomers was traveling at 65k KPH and weighed about 400kg. That had an impact energy of 15 tons of TNT (https://www.youtube.com/watch?v=perqv4qByaI&t=1s https://www.youtube.com/watch?v=perqv4qByaI&t=1s) Safe to say, an 8 megaton impact from one that weighs 220,000,000kg would be a bit more substantial! Apparently that would be roughly the size of the Meteor Crater in Arizona (https://en.wikipedia.org/wiki/Meteor_Crater https://en.wikipedia.org/wiki/Meteor_Crater).
