“O friend and companion of night, thou who rejoicest in the baying of dogs and spilt blood, who wanderest in the midst of shades among the tombs, who longest for blood and bringest terror to mortals, Gorgo, Mormo, thousand-faced moon, look favourably on our sacrifices!”  
  How do we model an orbit?  
  Well, we have a mass, say the earth, 5.98e10^24 Kg.  
  The radius of the earth is 6,378,495m.  
  Gravity = GM/r^2  

cent = v^2/r

  v = radial velocity  
  n = Nyarlathotep  
  c = Cthulhu  
  Azathoth = v*r  

the vast majority of mankind, are terrified by the obvious and trivial truth of the next great religion: Cosmicism, but haven’t the imagination to run howling into the night, screaming at the moon, and praise the embodiment of humanities utter irrelevance and the utter irrelevance of all human concerns and understanding in the face of the vast emptiness of the universe: Cthulhu.

They seek a belief that makes them special, a secret knowledge that grants them a perceived meaning in the face of their personal perception of meaninglessness and total impotence in the face of worldly events, much less cosmic disasters and the ultimate fate of the universe.

Some would say Fear Not, for your salvation is at hand, but they lie, that they might maintain their illusions of significance.

There is no salvation from reality, the infinity of the cosmos and unending time that ends in total oblivion and the extinction of all being which never, ever, ever ends when every individual particle in the universe moves beyond the observable horizon of every other particle as is inevitable.
