Hi all -

Everybody loved Clyde, so they don't want to take the
honor of discovering a planet away from him. But for
the future, making him the discoverer of the first KBO
would not be that much of a demotion, and might be a
raise - that is the FIRST KBO.

Minor Planets are those located between Mars and
Jupiter at some point in their orbits, plus a few that
are betweeen the Earth and Jupiter.

I hope this clears everything up.

Now while they're all together there, do any of these
guys and gals know where the 64 fragments of
Schwassmann Wachmann 3 are going to be in 2022?

good hunting,
Ed
