aw man, the first time in my life that I'm wrong and wouldn't you know, toseek is there! :wink:

j/k. thanks for the correction. I'm going to do some googling and see what the complete history of the cape is. I'm not aware of any mechanism that would change the inclination of an orbit except for interation with another body, and tidal forces. When you say the moon's inclination changes, are you sure you're not thinking of libration?
