Pluto doesn't have a moon in the real sense. Pluto and Charon orbit a
common center of mass
that lies beyond Pluto. Our moon and earth orbit a center of mass that is
located within the earth. Ergo, Pluto and Charon are not directly linked
gravitationally....

Try not to be so stooopid Thomas. Any two bodies gravitationally bound
orbit a common center of mass. The laws of mechanics could care less
where that center of mass is with respect to the surface of one or both
bodies. You want a link?

Try to learn to spell..it's stuuuupid... not stooooopid. And no, I don't
want a link
I want your personal mathmatical explanation
Of course they are gravitationally bound but not as directly as if the COM
was inside Pluto.
The earth wobbles around the COM and it's innards slosh around and the tides
come in as the moon orbits.
What is the exact nature of a center of mass or fulcrum? Balance..a
question of balance.

That is one of the best pieces of nonsense I've read in a very
long time. The barycenter of the Solar System does not lie
within the Sun, thus by your reasoning the Sun doesn't have
planets, either.

That's for today's Earth-Moon system ...
As the Moon recedes, you're saying Earth is no longer linked to the Moon
gravitationally? that the Moon is no longer a satellite? (The Moon already
orbits the Sun; what more do you want?)
The real issue is if it's cleared out it's area of gravitational
competitors, not where the barycenter of the bodies' rotation lies.
HAve fun,
Frank

There seems to be a few here that can't read. Maybe my words are wrong but I
said
INDIRECTLY. And this is only about the planet-moon argument.

No, there seems to be one person here who is missing some fundamental
physics. There is no such thing as being "directly linked
gravitationally", nor indirectly. The physics of two bodies in orbit
around each other (barycenter outside of both) is exactly the same as
the physics of one body in orbit around another (barycenter inside of
the more massive).
Certainly your words _are_ wrong. Unless you can come up with better
ones, or explain yourself more clearly, there is no option but to also
conclude that your ideas are wrong.

you're exaggerating. way out out there bud! go work out the Earth - moon
system then come back.

Whoops. Good start, but you stumbled on the conclusion ...

The operative word here is directly as like the earth moon system. That
should be obvious

Holy Hilda! That means there are no planets at all! Woooooooooops.
The Sun is a crystalline sphere afterall, orbiting vestal virgins!
