Final answer:
The inhabited 'forest moon' Endor in Star Wars Episode VI: Return of the Jedi is an unusual situation because moons in our solar system typically orbit around planets.
Step-by-step explanation:
In the Star Wars movie Star Wars Episode VI: Return of the Jedi, the key battle takes place on the inhabited 'forest moon' Endor, which is said to orbit around a gas giant planet. This situation would be unusual based on what we know about planets and moons in our solar system because typically, moons orbit around planets, not other moons.
