Only 12 miles across. So small. Incredible, though that a solid rock would be 12 miles across, so large!
It’s 8 times the volume of the Chicxulub impactor. :’o
I live on the side of a big hunk of granite in N. Idaho that is about 10 miles running south to north and about 3 miles east to west and who knows how deep it goes. It has probably never been to space but it IS part of the Kaniksu lobe of the Idaho batholith.
I would NOT want to be a resident of a planet that got hit with this rock travelling about a gazillion MPH. Unless it landed on Washington, D.C. That might be worth it.
