The Wanderer
The evening sky was set alight
As the nomadic satellite
Took station at its settled height
Discovered in the subtle light
Of autumn sun
Thus the coruscating orb it
Acquired geocentric orbit
Concealed by clouds that absorb its
Transmitted data bytes or bits
So alien
Attracted by earth’s gravity
It had a strange propensity
For exploiting the parity
Of nearly matching density
As round it spun
Acquiring a trajectory
Swirling in strange symmetry
Passing through it’s perigee
Defiant of astrometry
Then moving on.

Simplified, astrometry is part of the discipline of astronomy that measures the movements of stars and other celestial bodies.
