The moon above which the [Death Star II]
? was constructed in the
Star Wars movie [The Return of the Jedi]
?. Home to Ewoks, the cute (some say too cute) furry deziens who help the Rebel Alliance defeat the forces of the Empire. Interestingly, all life on Endor should have been snuffed out shortly after the end of Ep 6. See

The moon's name comes for the Elven word for Middle-earth in The Lord of the Rings, probably an allusion to the similarity between the moon's tall foliage and the mallyrn of Lothlórien?.
