the phibìc Pole of every planet.
We also assume the the direction is no at 90° perpendicular to the axis of any kind of two planet.
Assume we now define an stimulate on the collection of world by saying that world A ≥ B, when removing every the other planet from space, the north pole B, is visible from A.

If we refer to the direction the the planet in the diagram, we discover that,
1, A ≥ A
2, If A ≥ B and also B≥ A,
Then A = B
3, If A ≥ B, and also B ≥ C , climate A ≥ C
4, one of two people A ≥ B or B ≥ A
It should also be provided that the variety of order over has a distinct maximal facet (M). This is the only planet whose phibìc Pole is not visible native another.
