My understanding is that the steam released from the flash boiling of water vapour in the rock would be enough to push an asteroid off course enough. As long as it was sufficiently far away.

Infinitesimal chance of rocket exploding that could never even set off the nuclear chain reaction, vs possible planet killing asteroid impact.🤔

If you pick it up from far enough away, it wouldn't take much to knock an asteroid off course. Pop a nuke next to it and knock it off course by a degree, and it would miss us by 1000's of Km.

Easier for a space faring species to get those from asteroids and comets than from a planet.

It depends on if the planet has left or right based dna and/or sugars.
A planet could seem perfectly habitable on the surface, with regards to temp, oxygen levels etc, but be completely useless to an invading species due to incompatible flora and fauna.

Unless it's was a solid metal of some kind, I believe it is a given that any rock based asteroid would have some level of moisture/ice in it.
