Hey, IAttack....
Good info!
Regarding satellites, in formation. You are absolutely correct.
As observed from the surface of the Earth, the satellites in question would (mostly) have to be illuminated by the Sun in order to be seen, right?
And secondly, if they were at variously different 'heights' in their respective orbits, their speeds would obviously vary. Not that it would be
obvious to the casual observer, in the course of a few minutes, as they happen to pass overhead.
To clarify.....three objects, deployed in an orbital path, at the same 'height' above the surface...and assuming no relative motion between the
three....would, assuming no interference, stay in relative position for a very long time. Of course, after many, many years, there might be a
gravitational attraction to each other, and they will tend to creep towards each other....but not in a human's lifetime, if they are far enough apart
to begin with.
But....as think as Earth's atmosphere may be at those heights...it is still, while thin, they're in LEO (Low Earth Orbit). So, eventually over
time, anything in LEO will find its orbit degrade to the point that it will decelerate, and eventually re-enter. To burn up.
