Are two planets adjacent when the border between them is thin?
The rulebook states this directly.

Yes. Systems sharing a thin border are adjacent, including planets in different clusters across the oval edge. Only a thick, irregular border blocks adjacency, and a border that is thin along any part still lets ships cross.
