I'm guessing this isn't a great physics question, but I just can't find an answer with Google. If the galactic plane is perfectly horizontal at what angle and rotation will the ecliptic plane of our Solar System be?

  • $\begingroup$ Are you asking for the angle of inclination of the solar system's ecliptic plane with respect to the galactic plane? $\endgroup$

  • $\begingroup$ @David: I think so. I think he's also asking for the precession speed of our SSEP with respect to the galaxy's reference frame. $\endgroup$

The answer seems to near 60 degrees. Additional description here

I have found this mathematica description of the ecliptic plane relative to the galactic plane.

    $\begingroup$ @space_cadet Well the 1st image certainly isn't real (as in to scale) $\endgroup$
