While the average size of a zero magnitude cometary meteoroid is "pea
sized" there are others as large as a football (that would make a nice
sight in the sky) and those smaller than peas. It is the tremendous
velocity (up to 40 miles per second) that makes these tiny objects
visible as bright flashes from so far a distance.

The chances are slim that a Leonid particle will actually collide with a
satellite causing damage. Even during "meteor storms" these particles
are several miles apart (on average) and space is still quite empty.
Should the unlikely occur and a Leonid meteoroid strike a satellite, the
damage would not be from a puncture since the density of a Leonid
particle is much like ash. Rather the damage would be to the electrical
circuits on board due to the kinetic energy released during this
I hope this helps!
