Just to clarify. The Schrodinger Impact Basin, which the article
refers to, is 312 km across. This is 50% larger than the Cicxulub
Crater the ended the dinosaurs, which was crated by an impactor
10 km across.

The current asteroid, 2024 YR4, is about 60m across, and about
one five millionth the mass of the Chicxulub impactor. Its a city
killer, not something that would cause a mass extinction.

Silly question perhaps, but could a standard ICBM be fired into space
and have a hope in hell to (when detonated) turn a collision into a
near miss?
(Am pretty sure I read an SF story where this was a theme)
No, not really. ICBMs are not made to reach escape velocity to start.
