Endor is a fictional moon in the Star Wars universe, known for its endless forests, savannahs, grasslands, mountain ranges, and a few oceans. The moon was the site of a pivotal battle depicted in Return of the Jedi. Homeworld of the sentient Dulok, Ewok, and Yuzzum species, as well as the semi-sentient Gorax and Wistie species. The Endor solar cycle was 402 GSC days orbital, with a breathable earth-like atmosphere conducive for humans and 8% surface water. It is the gravesite of Darth Vader.

The moon orbits Tana—the Ewokese word for Endor's host planet—a gas giant located in the Endor system, a binary star system positioned in the Moddell sector of the galaxy's Outer Rim Territories.[1][2] Located in grid square H-16 on the Standard Galactic Grid, it was connected to Cerea and Bakura by a hyperspace route.[3] The planet was orbited by nine moons, the largest of which was known as the Forest Moon of Endor or "Sanctuary Moon".[4] The ocean moon of Kef Bir was also one of these moons, and is the location where the second Death Star crashed after it exploded over Endor in Return of the Jedi.[5] It also had two suns: Endor Prime I and Endor Prime II.

The Forest Moon of Endor first appears in Return of the Jedi, in which it is the body in whose orbit the second Death Star is constructed, and is the home of a race of furry aliens called Ewoks. The moon later appears in the original Star Tours Disney theme park attraction, Ewok TV movies The Ewok Adventure and Ewoks: The Battle for Endor, as well as the animated Ewoks and its Marvel Comics tie-in series.

Various descriptions of the Endor system exist in various media. Special effects storyboards for Return of the Jedi refer to a distant orb in the system as "Planet Endor". According to the Return of the Jedi novelization, the planet disappeared in an ancient cataclysm. The Ewok television films depict a gas giant in the sky, and novels such as The Truce at Bakura and Dark Apprentice also mention a planet visible from the moon. The planet is called "Tana" in the Ewoks animated series, which also depicts a binary star system (while other sources depict only one sun).[6]
