The Thousand Moons system is identified as a star system. During the Separatist Crisis of 22 BBY, Senator Padmé Amidala and the Jedi Anakin Skywalker acted as refugees originating from this system. This was part of a plot to protect Amidala from an assassinate attempt. While traveling from the planet Coruscant to the planet Naboo aboard the AA-9 Freighter-Liner Jendirian Valley, Amidala wore a yellow headress that was styled after the Thousand Moons system to maintain her disguise.
The canon of Star Wars mentioned the Thousand Moons system in the "Starship Fact File" section of the 2015 publication Star Wars: Build the Millennium Falcon 50, authored by Tim Veekhoven. The system's origins are in the Star Wars Legends community, specifically the 2002 reference book Star Wars: Attack of the Clones: The Visual Dictionary, penned by David West Reynolds.
