  Roche limit is quoted (in the Britannica) to be 2.5 diameters of the
primary. The 380 odd thousand kilometers of Luna's orbit are quite outside
the limit.

Ooops.  Ok.  It's my own fault for not checking facts before I sound off.  I
have that nasty habit.  Usually my memory is excellent for trivia of that sort,
and I tend to rely on it to the exclusion of other sources of information.
Hopefully, I will have learned my lesson from this semi-public humiliation  8+)

Seriously, tho, thanks for straightening me out about that.

Paul.
