An episode of Star Trek TNG had a spacecraft in what was
apparently a stationary orbit over the north pole, which just
about turned me inside out. BAD physics to the max!

The notion that bodies orbit the center of mass is so ingrained
in me that it seems completely intuitive. I can't remember a
time when I didn't know it. Certainly I knew it when I traced
John Glenn's flight in Friendship 7 around my new globe.

Everything falls toward the center of mass.
