The milky way galaxy is about 200,000 light years in diameter, but only about 200 light years thick.
Given this thickness, I imagine you'd need to look beyond the 200-light-year range to notice a significant influence of the plane of the galaxy on the distribution of stars (and planets).

Every eighteen year-old suburbanite[1] has already been pretty well socialised by local interactions in the context of a global system of local interactions, performed massively in parallel.

- IanCal 11y agoI love this galactic orbit measure of things. Dinosaurs like the Iguanadon were alive ~125mya, which means that the impressive thing when looking at a fossil is not that it's old, it's that it came from the other side of the galaxy. You can go and pick up a trilobite that's coming up to its third orbit. Yes, I know, it's still from Earth, but I do think it's a weird way of looking at dinosaur fossils.
