Copernica is a land of make-believe and fairy tales, where the citizens are all dizzy from simultaneously spinning around the Poles, the Sun, the galactic center, the local cluster center, etc. Copernica is covered with perpetual darkness, as the dwellers therein ? love the darkness more than the Light.? Copernica borders closely with Darwinia and Einsteinovia. The planets are secondary satellites of Earth, since their primary object, the Sun, is itself a primary satellite of Earth. That is, they are satellites of a satellite. Phobos and Deimos are tertiary satellites of us ? satellites of a satellite of a satellite. This is the hierarchy of the universe He created.

Or is that another planet? What is the difference between a primary orbit of a planet and a secondary orbit of a planet? Mystified.. Phil
