Docked rotating entities will show up in the planet sector as an orbiting entity if the station they are docked to is in the 26 sectors surrounding the planet.
Procedure:
- make a station with a constantly rotating docked entity, located in one of the 26 sectors forming a box around the planet, not the planet sector itself
- target the entity
- enter the planet's sector while still targeting the rotating entity
You should now see the entity constantly orbiting.
