Re: Planets and Moons

This was supposed to go to the list, but it went to Barry Garcia, instead.
Some people's systems are set up so that the listserv makes them, instead of
the listserv, the primary returnee.  Ray's complaint.  So here it is again:

I enjoyed looking at these pages, too, but I didn't find any information
among them for constructing a system where two Earth-sized planets revolve
around each other.  Maybe it's an impossibility.  I was especially
interested to learn that the denser the planet, the closer it had to be to
its object of orbit.  The pages give examples with moons:  the less dense
the moon, the further it has to be from the planet in order to revolve
around it.  I wonder why this is.  But it obviously explains, doesn't it,
why our gaseous planets are further away from the sun while our rocky
planets are closer.  Right?  :)   This is interesting in light of recent
discoveries of gaseous planets (or at least their traces) in distant
systems.  It could mean that we can't see rocky planets closer to the star.
