If the surface is that soft, the thruster would have to be carefully designed to have a large surface area so that it doesn’t drill straight through.

When I look at the surface, I realize that they could never hit such an object with a kinetic weapon or nuclear bomb. It would just shatter into a billion projectiles. It would take dozens of years perhaps hundreds before the majority of the objects, captured by gravity in elliptical orbits, crash into the earth or moon.
The movies made it seem a simple problem to solve, just blow it up. It appears the only rational solution is to keep the comet intact.
I like the proposal of landing a thruster on its surface, and gently nudge it on a new course. For this to work, we are going to need to locate potential near earth comet and astroids far ahead of time when a small nudge can move it out of danger. We start by creating many eyes and radar stations in orbit.
The best place for great observations and triangulation is on the far side of the moon. Four or more bases stationed where at least two can identify an object and track it at a great distance.
It wouldn’t hurt to install a very large permanently maned science station with huge telescopes and listening ears outside the atmosphere of earth. It would advanced our knowledge of the universe a hundred fold in one generation.
It would only take one of these Comets glancing off the moon to destroy the satellites and set us all back to a time before the space-age… for a very long time.
This must be prevented if we can. We have too much to lose, the technology is within our grasp. Mars is interesting, but it can wait.
