They have had a psyker move a planetoid out of it's course before in "The Serpent beneath"

Then again physics are a thing, too.

1. Wasn't the Vengeful Spirit locked inside the Eye of Terror, where the laws of physics become malleable?..

2. In a 0g environment, it should be easier to move because you have neither gravity  nor "air resistance" working. There is the point of action = reaction and so on, though.

3. All legions used Librarians on Terra, only after the Primarchs made their influence felt,did that change.
