I do not believe “topology is orbital mechanics” is true for IP routing.  Yakov’s law is specifically about the IP routing topology, not about either geography on earth or orbital mechanics in space.  

As a contrived counter-example, communications between Venus and Mars could go directly between those planets without needing to traversing Earth, even though Earth’s orbit is at a distance farther than Venus from the Sun and closer than Mars from the Sun.
