The Observatory Moon existed as a moon, revolving around a gas giant world. It housed an observatory managed by Kh'ymm. In approximately 9 ABY, Jod Na Nawood, known to Kh'ymm as Crimson Jack, transported a collection of stranded younglings to this moon with the expectation that Kh'ymm could direct them toward their home planet, At Attin. Kh'ymm aided the children; however, she also summoned two New Republic X-wing starfighters to apprehend Nawood, prompting him and the children to flee, taking the supposed coordinates of their planet with them.
The Observatory Moon was featured in "Very Interesting, As an Astrogation Problem," the third installment of the Star Wars: Skeleton Crew live-action series on Disney+, which was broadcast on December 10, 2024.
