In the star wars movie star wars episode vi: return of the jedi, a key battle takes place on the inhabited "forest moon" endo, which supposedly orbits around a gas giant planet. from what you have learned about planets and moons of the solar system, why would this be an unusual situation?

This would be an unusual situation because from what I've learned by studying the moon and the planets in the Solar System when a moon it is orbiting around a gas planet, it is uncommon that the moon could have some forms of life, like in the moon from Star Wars. A moon can host forms of life in an easier way when it is orbiting a rock planet.
