[edit] IAU definition

Does the definition used by the IAU change with the Earth's precession? Also, is there any plan to extend it to other solar systems? Wnt (talk) 19:36, 1 June 2008 (UTC)

[edit] Galactic poles

This article could probably use some discussion and explanation of the galactic coordinate system which uses the IAU definition of north and south galactic poles, of course. I've sometimes wondered about the right-hand rule with regard to rotation (the Milky Way is upside down in this regard, as is the Earth with regard to its own magnetic field), and I'm sure people who research the galactic magnetic field have their own questions. arkuat (talk) 10:47, 13 June 2008 (UTC)
