First, I wanted to thank you, Robert: ever since (re?)joining our list,
your posts have been a model of informative and succint communication.
THANKS for participating: I know the amateur meteoricists of the world (or
at least the ones on this list) appreciate it! ;>
Second, I wanted to ask a question on the above: wouldn't it be more
correct to say that the EFFECT of orbital position uncertainty was the same
for mile-wide asteroids and 1 gram meteoroids? After all, aren't some of
the MECHANISMS in the two cases different? I'm thinking for instance of the
Poynting-Robertson effect, or outgassing pressure from comets, etc.
Thanks again, and clear skies to all!
