<p>For me, it makes a lot of sense. However, I’d add one more layer:
I would suggest a separate `/3` subnet just for planets
(unfortunately other planets than earth) and another `/3` for
other objects (like asteroids or Pluto, which isn’t actually a
planet). Addresses for natural satellites would fall within the
address space of their respective planets.”</p>
