First. The orbit of the Humanity Star is above where the airframe of an ICBM would ever get. Stage 3 separation of a Minuteman III missile occurs at about 55 miles, +- depending on the target. The orbital altitude of Humanity Star is much higher than that to allow it to even maintain orbit for the nine month mission.
Second. After Stage 3 separation the Propulsion System Rocket Engine will burn for a few minutes or less to adjust velocity and trajectory before separation of the re-entry vehicle (RV). Once the RV is released it will finally end up intersecting the orbital height of the Humanity Star and the probability of collision is astronomically small. If they did collide the speed of the RV combined with the speed of Humanity Star would destroy both immediately. The kinetic energy of even a glancing blow would be so great as to destroy them and the pieces of the RV, due to the initial trajectory, would not be able to travel far enough to clear the Pacific Ocean.
If somehow they just grazed each other and remained intact the RV would still not have the energy or trajectory to do anything but hit the ocean.
Next thing I suppose you’re going to try to convince me is that guy riding the bomb in “Dr. Stranglove” was fake!
After I wrote it I did sort of figure that the orbits would be way off.
“If they did collide the speed of the RV combined with the speed of Humanity Star would destroy both immediately.”
I do find THAT to be interesting! I suppose the speeds are so much more than what I think they are, and would overide the mass of the larger object. (F=mA, with A >>>>>> m?)
