The hoax claimed that the gas giant Endor has previously been destroyed in some manner of calamity. This notion was easily refuted by its continued existence in orbit of its star, Ibleam, and of the Forest Moon of Endor's position in orbit of the planet.
Behind the scenesEdit
The planet Endor was never visible in any scenes in Return of the Jedi set on the forest moon's surface. The novelization claims that Endor was destroyed some time earlier, and that the moon now orbits its star in a planetary orbit of its own.
