So, here are a few potentially interesting locations:"Oort Edge" is the rough outer limit of the Oort cloud, and hence the a good a place as any to declare the edge of the Solar System. Alpha Centaur...

This topic has come up once or twice before, but I don't think it has had its own thread yet. The issue, as I see it, is that the "size" of each toposophic level is much larger than the one below it....
