I was thinking local perspective, as seen through a telescope. To be more precise, any number of extra-solar planetary orbits that are perpendicular to our line of sight could have several orientations around the Z-axis (the axis of the line of sight).

The planets of our solar system inherited much of their angular momentum from the sun as they condensed. I was wondering if stars had a similar relation to the galaxy as a whole. Kepler is looking at a spot on the galactic plane, so that variable is at least removed.

Our solar system does not, and it seems there's no way to tally up other ones until we figure out a more comprehensive method of detecting planets.

It's likely that the galaxy as a whole has a lot of chaos that has intervened with stellar orientations, much like some of our outer planets have been tweaked a bit since their formation.
