I didn't mean to say that the Sun doesn't affect the Moon. "If what J-P 
wrote were true, the Moon would not orbit both the Sun and the Earth, as 
it does, but only orbit the solar system's center of gravity (if we 
ignore the rest of the universe)." Is that better?

You can't choose your words too carefully when there are Ada language 
lawyers in the audience. :-)
