For that matter the out gassing from coming near the sun has a
much greater influence than this impact ever will. One grain of
sand does not make a beach.

Ellis, temple1 doesn't approach the sun. Mars and jupiter play catch with
it. But 1000 kilometers a year difference is going to put an end to it.

The whole point of a stable resonance is that
any small perturbation such as is produced by
outgassing tends to change the distance at the
next close encounter to the planets in a way
that causes a correction to the motion to
restore the object towards the original path.
Otherwise it would have drifted out of the
pattern long ago. Since the delta_V from the
impactor will be less than the cumulative effect
of outgassing, there is no risk of changing its
orbit permanently.

Temple one isn't going to be a anomaly any more it's now back to space
debris for it. condemned by NASA.

Like firing a .22 at a snowman, the risk of
explosion is "low".
