3 types of asteroids come to mind. Asteroids that make up a bunch of rocks
will most likely get back together if we'd use a nuke, if they don't we'll be seeing a nice and big meteor shower. Asteroids that are solid
, are next to impossible to destroy in small enough fragments. It would make a but load of smaller problems out of that single problem. If it's a loose sand/mud like asteroid
, the nuke's impact will be absorbed.
Tunguska was probably a 10-20 meter asteroid, it didn't even hit the earth properly and was able to completely destroy 2,150 square kilometres of land. So even if we'd be able to break up this 270meter asteroid in pieces of varying sizes say... 50 to 1 meter. And one of those fell near a populated area. Those people better be DNR.
That said. I don't think it will hit.
