An investigation into the effects of momentum transfer deflection methods, specifically kinetic impact and nuclear detonation, on the rotational state of a deflected object is presented. Initially, a simplified model is developed and applied on ellipsoid analogs. The model is then expanded to, and applied on, polyhedral asteroid shapes. The results show the presence of deflection side effects to rotation, introduction of precession, and change in angular velocity magnitude, with the existence of a lever arm between the deflection direction and deflection interface location with respect to the body’s center of mass. At times, these rotational side effects can lead to structural instability that might counteract the deflection or completely disaggregate the object.
