OK, I am seeing how this all ties together. The polestar for Triton and the polestar for Nereid are, of course, different, and over longish periods of time their respective polestars change, just as ours on earth does. And the polestar for every particular object in the solar system (well, I bet Jupiter's Galilean satellites are all very close or the same) is different.

Is their a nice list of the polestars for all the solar system objects somewhere? I would be very interested in Neptune's and Iapetus' polestars.

This get back to me wondering some months ago if Iapetus' orbital plane about Saturn is rather more closely aligned with the ecliptic (BTW, is the ecliptic the ecliptic, or do we recognize Saturn as having one different from that we define from earth?) and whether or not that alignment to the ecliptic is expected to be stable over the age of the solar system.
