  REMARKS
Wolf 359 will prove to be a well placed hub for several further destinations.
NOTABLE EXCEPTION: Lalande 21185 might be the second closest neighbor; however, both W..359 and L..185 are about same distance from Sol (≈ 13 LY). Thus, W..359 makes no sense for L..85; though, it works well for the others.
