Here's something that I've been pondering, and was wondering if anyone on the BABB might have insights on.
As I understand it, the ecliptic plane for our solar system is (very roughly) perpendicular to the disk of the Milky Way. But what about the other solar systems that we are finding nowadays? How are their ecliptics oriented with respect to the Milky Way.
I would expect that the orientation would be entirely random, but I haven't seen any data about the extrasolar planets' orbits to support this. Mostly because I haven't been getting the data from the primary sources (mostly I get it in digest form). I don't know that I'd be able to interpret the figures if I saw them in any case.
So: is there any sort of pattern in the orientations of the various ecliptic planes, or is it a random assortment as I suspect?
