Jedha was a small desert moon which orbited the planet NaJedha. Located in the Jedha system of the galaxy's Mid Rim, the moon had a cold climate due to its lasting winter. The historical and spiritual significance of Jedha led the moon to become a world of worship for those who believed in the Force, and a holy site for pilgrims who sought spiritual guidance.
Some time before the Battle of Yavin, the Galactic Empire occupied the moon to control its kyber crystal resources that were once used by the Jedi Order as components for their lightsabers. The occupation later provoked an insurgency to oppose the Imperial tyranny, coordinated by the rebel extremist Saw Gerrera. Jedha's heritage and Gerrera's resistance—the aptly named Partisans—led to it being chosen in 0 BBY for a test of the Death Star's superlaser, a superweapon capable of destroying entire planets. Though Director Orson Krennic had planned to destroy the moon, Grand Moff Wilhuff Tarkin overrode him, stating that the destruction of the Holy City would serve as a sufficient test.
Jedha was a moon located in orbit around the planet NaJedha, situated in the Jedha system of the galaxy's Mid Rim, due galactic west of the Deep Core. 11,263 kilometers in diameter, Jedha was a small desert moon defined by its jagged rock formations, broad mesas, and narrow spires. Frosted by a permanent winter, Jedha had a cold climate and an atmosphere breathable to oxygen-breathers, such as humans. Within the moon's sandstone crust were rich deposits of kyber crystals —Force-attuned crystals that were fundamental in lightsaber construction. Many settlements on the moon, such as the ancient Holy City, sat atop the world's natural mesas. Though Jedha's sands remained parched for much of its year, there were instances of powerful torrents of rainfall, a cause for celebration among the people of Jedha.
Jedha's ancient structures were some of the earliest examples of architecture known to exist in the galaxy. The withered sandstone structures and statues dotted Jedha's landscape, a testament to its ancient past.
Being an antiquated destination, Jedha was surrounded by uncharted systems, making it a reliable replenishment port for travelers.
